Version 0.9.3.9, December 12, 2001
----------------------------------

XML:    Added support to the Schema Object Model for a number of XML Schema
        attributes / properties such as elementFormDefault, form, 
        attributeFormDefault, abstract, id...etc that were previously not
        read in from the XML Schema. Validation still needs to be updated,
        as well as the source code generator (kvisco - 20011129, 20011205)

XML:    Added QName support in the marshalling framework (when used via the mapping or via
        the Source Code Generator) (Arnaud)


XML:    Added special code to prevent creating a default XML name when using the "matches"
        attribute for bind-xml element in the mapping file. (kvisco) 20010815

XML:    Fixed bug with introspector...first character of field name was not being
        decapitalized. This caused a bug in the "auto-complete" feature.
        (kvisco) 20010815

XML:    Fixed bug with "auto-complete" when specifying an identity field, the field
        descriptor was not being set. (kvisco) 20010814

        (andrew.fawcett@coda.com, Andrew Fawcett)

XML:    Fixed problem in Schema unmarshalling (when using both xsd:include and xsd:import),
        allowing a given schema to be  parsed a second time, resulting in duplicate type errors.
        (andrew.fawcett@coda.com, Andrew Fawcett)

XML:    Added an option (default is off) to expose the names of each attribute and element described in the class descriptor.

XML:    Fix a bug when handling attibutes in the UnMarshallerHandler (bug reported and
        patch submitted by Marcin Chalotowski <Marcin.Chalotowski@3dart.com>) (Arnaud)

JDO:    Fixed a old values appears in new result problem.
        (reported by Jim Branecki [Jim_Branecki@sparta.com]
         and Steven Lee [steven@lee-home.com])

JDO:    Added setAutoStore to JDO and DataObjects (necessary for use in EJB environment). (oleg)

JDO:    Fixed the rs.next() called more than one problem. (yip)

JDO:    Fixed IllegalStateException when TransactionManager calls
        afterComplete( Status.ROLLEDBACK ), without calling
        beforeComplete() first. According to the JTA specification,
        rollback can be one-phase.
        (reported by Richard Monson-Haefel [Richard@intalio.com]
         and Matthew Jensen [mmj@ceg.net])

JDO:    Made the BatchUpdateSQL utility to take small letter "go" as end
        tokens of a statements. (yip)

JDO:    Added special care for Double/Float type to workaround a oracle's problem. (yip)

JDO:    Splitted create() phase into two phases: markCreate() and create().
        In the markCreate() phase, the object to be created is walked and all
        objects that should be created are marked. Then, the marked object is
        created in the order that is determined by getPriority(). After the
        creation, object cache that related to other is updated.
        (similar changes was made to update())
        - The change is introduced to solve several problems related object creation.
          (The old apporach try to delay the creation of dependent object to preStore
          state, so that the master object is always created first. The master generated
          key would be ready when dependent object are created at transaction prepare.)
          bug 1: dependent's related object is not automatically created,
                 even if autStore set true. (with key gen used both side)
          bug 2: 1:1 dependent relationship is not always done right, depends on which
                 side is the foreign key placed. (with key gen used both side)
          bug 3: in some tricky suituation, created object cache is not updated. (yip)

JDO:    Fixed a bug in the FieldMolder.isStored() method. (yip)

JDO:    Fixed the problem with two 1:N relations between the same two tables (reported
        by CORMONT Cedric <cedric.cormont@softeam.fr>). The solution is to use aliases
        (when needed) in outer joins generated by SQLEngine. (oleg)

JDO:    Restricted JDO to eat only ObjectNotFoundException now to workaround
        inconsistent reference in database. (yip)

JDO:    Fixed a NPE in TransactionContext.load().
        (reported by Naveen Sharma [sharmn@sdd.comsat.com])

JDO:    Fixed bug in JDBCQueryExpression.getSelect() that previously
        was hidden in ancestors. (oleg)

        to be thrown in ClassMolder.
        (Bug reported by (Naveen Sharma [sharmn@sdd.comsat.com]))

JDO:    Added type convertor of BigDecimal<-->Short and BigDecimal<-->Byte. (yip)

JDO:    Fixed a deadlock problem.
        (Reported and submitted by Holger Krug [hkrug@rationalizer.com])

JDO:    Treated an SQL generation issue temporarily. When users write an OQL
        contains two or more conditions on the same one-to-many relation,
        s/he expects OQL to return the union of the two conditions, but it
        is returning the intersection now.
        (Patch submitted by Rehor Petr [petr.rehor@decros.cz])

JDO:    Fixed a StackOverflowException. The Exception was caused by an infinite
        loop in getPrority().
        (Submitted by Mark Lamb [Mark.Lamb@spirent.com])

JDO:    Fixed a problem causing unexpected ObjectModifiedException being thrown
        when an object in one side of 1:1 relationship is being added via a long 
        transaction. (yip)
        (Reported by Sharma, Naveen [Naveen.Sharma@lmco.com])

JDO:    Fixed the default value not being used for primitives bug. (yip) 20011025

JDO:    Fixed the 1:1 dependent object not being created when the it is newly
        link, or replaced to the master object in both long and short 
        transaction. (yip) 20011025

JDO:    Added support of read-only field for Castor JDO. Read only can be
        enable setting read-only attribute to true inside sql element in
        the mapping file. (eg. <field><sql read-only="true".../></field> )
        20011029
        (Patch submitted by Jakob Braeuchi [jbraeuchi@hotmail.com])

        [reported by BEDNARIK,LASLO laslo_bednarik@hp.com]

JDO:    Fixed a problem that causes Castor JDO always requesting writeLock for a
        data object with a lazy-loaded collection. (yip) 20011126
        (bug reported by Dominik Baranowski [dbaranowski@saltare.com] and
        Ned Wolpert [ned.wolpert@knowledgenet.com])

JDO:    Fixed a problem that causes <field set-method="..."/> doesn't work.
        20011130

        patch submitted by Jakob Braeuchi [jbraeuchi@hotmail.com])

JDO:    Fixed the integrity problem with many-to-many relationship.
        (reported by many users...) (yip) 20011130

        file does not work. 20011203
        (Bug reported and fix submitted by ryoder@q-markets.com)

JDO:    Fixed a potential problem with lazy collection consistency.
  
        If an object is removed from database, and the lazy collection
        still link to it at the end of transaction, the cache would
        still "think" the object is in the database in the next
        transaction.

        Although the test can detect that in some case, it is not
        recommended to depends on this behavior. Always dis-link it,
        before calling db.remove(). (yip) 20011204

JDO:    Added sqldate and sqltime as supported field type. (yip) 20011204

        (Submitted by Todd V. Jonker [tjonker@inpathsol.com])

JDO:    (doc) Added a FAQ for pass-thru SQL.


JDO:    (test) Added a 2 second sleep in between the creation of the first
        and second object. This is needed to make the test case run properly.
        Because, some database stored time in less precision, and it causes
        the test to fail. (yip)

JDO:    (test) Used a new SQL connection in the inner class of the test to
        workaround a problem in Solaris. (yip)

        (Kim Madsen <kim.madsen@inceptor.com>)

JDO:    Added SQL Direct Interface. Syntax:
        "CALL SQL <sql expression> AS classname". The fields that are returned
        with you sql query must be the same, as the equivalent OQL Query would do.

        This option only affects JDO if transactionManager is set and
        a transaction is associated with the thread that call
        getDatabase(). If jdo Database pooling is enabled, JDO will
        first search in the pool to see if there is already a Database
        for the current transaction. If found, it returns the database;
        if not, it create a new one, associates it will the transaction

        on March 8th, in the version 1.45 of DescriptorSourceFactory. (kvisco)

XML:    Added fix for enumerated simpleTypes. When a simpleType restricted another
        simpleType, if both types defined an enumertion facet with the same value
        Castor wouldn't handle this properly. Bug reported by Stephan Goetter.
        (kvisco)

XML:    Added fix for generating source code using the element-method. Classes
        were no longer extending their abstract type definitions. (kvisco)

XML:    Add a command line property for the Source Generator to use the generated files in
        the Castor Testing Framework(Arnaud)

XML:    Add a property in castorbuilder.properties to generate a clean 'equals' method (Arnaud)

JDO:    Fixed bug: dependent collections with key generator where updated incorrectly
        (reported by Ivica Rimac <ivica.rimac@KOM.tu-darmstadt.de>)

JDO:    Added possibility to use in a query condition object references that correspond to sql field.
        In this case the object of a persistence capable class should be bound as a parameter. (oleg)

        (David J Snowsill <david.snowsill@calibreft.com.au>, oleg)

Version 0.9 February, 15 2001
-----------------------------

XML:    Adding a new feature for handling all types of content and not only TEXT content (Arnaud)

XML:    Change the read method name for arrays (Arnaud)
        (bug reported by thebuledirt@yahoo.com)

XML:    Several bug fixes in the SourceGenerator concerning the attribute string value (Arnaud)

XML:    Added improved grouping support. Grouping support is not finished,
        but is definately improved over Castor 0.8.11. 1st-level choice is
        now supported. (kvisco)

XML:    Added enumerate() method to generated enumeration types. (kvisco)

XML:    Added support for specifying certain properties of the Introspector, such
        as whether primitives should be treated as attributes or elements, and
        default naming conventions. (kvisco)

XML:    Updated mapping.xsd_sg to be compliant with latest XML Schema. (kvisco)

XML:    Added support for DOM in Marshaller.java and Unmarshaller.java
           (Andrew Fawcett andrew.fawcett@coda.com)

XML:    Added setPolymorph method to Marshaller.java. This can be used to force all field values
           to be marshalled as their field types rather than their instance types.
           (Andrew Fawcett andrew.fawcett@coda.com)

XML:    Changed the default behavior of the Xerces Serializer to preserve space
        by default.
        (Sebastien Gignoux <gignoux@intalio.com>)

XML:    Added support for restriction in simpleContent and enhanced complexType support
        (Arnaud <blandin@intalio.com>)

XML:    Added the command-line option '-nomarshall' which aims at preventing the
        generation of the marshalling framework specific methods (marshall, unmarshall, validate)
        (Arnaud <blandin@intalio.com>)

XML:    Added setNSPrefixAtRoot method. When used in conjunction with setNamespaceMapping this
        will insert the namepsace declarations at the root node.
        (Andrew Fawcett, andrew.fawcett@coda.com)

XML:    Fixed collection handling for introspected class.
        (Sebastien Gignoux <gignoux@intalio.com>)

XML:    Bug fix for using addXxx methods.
        (Fix submitted by Michael Thyen <mthyen@excite.com>)

XML:    Bug fix in the handling of 'Map' collection. Now we use the abstract
        'Map' interface rather than 'HashMap'.
        (Fix submitted by Ron Smith <rsmith7209@yahoo.com>)

XML:    Added some logic to avoid unnecessary use of 'xsi:type' when
        marshalling. The logic check if Castor is able to find the proper java
        class to instantiate from the mapping file information.
        (Sebastien Gignoux <gignoux@intalio.com>)

XML:    Solved a performance bug for unmarshalling of primitive type. We don't
        try anymore to generate a Class Descriptor for primitive type as we know
        that not only it fails but it is deadly slow (due to getMethods()
        call). Now, unmarhsalling speed is nearly only bounded by the speed of
        the parser.
        (Sebastien Gignoux <gignoux@intalio.com>)

XML & JDO:
        Check that an XML mapping file do not declare more identity attributes
        for a given class than there are field elementsdefined for that
        class.
        (Patch submitted by Gabriel Richard Pack <gpack@electroneconomy.com>)

XML & JDO:
        Regenerated data objects in the org.exolab.castor.mapping.xml package,
        using an updated version of schema (Nov 2000).

XML & JDO:
        Now the return type of get-method must be a super-class of or equal to
        the class declared in mapping.xml (was: sub-class).
        Note, that now "arraylist" can be used as a value of "collection"
            attribute in mapping.xml

JDO:    Bug fix when castor closed Connection during db.close() (before the end of
        transaction) and the got new Connection during beforeCompletion(),
        which remains open after the end of transaction.
        (Solution submitted by Terry Child <tmchild@gmx.net>)

JDO:    Castor JDO should now behave shamelessly in a multi classloader context.
        This is especially relevant when used in a BMP/CMP environment where the
        EJB container might assign a ClassLoader instance per set of Beans, or
        might attach a different classloader for each new transaction.
        (Sebastien Sahuc <ssahuc@intalio.com>)

JDO:    Added an AutoStore option to JDO. Method of setAutoStore and isAutoStore
        are added into the jdo.Database interface. If autoStore is set, Castor
        will try to create or update** all reachable object if it is not
        exist in the transaction, and store all reachable modified object at the
        commit time. If autoStore is not set, Castor will only create/update/store
        dependent object, and related objects must be created/update explicitly.
        (* update is used for long transaction only, all modified object
        created/loaded from the short transaction will be store properly
        at commit time) (Thomas Yip <yip@intalio.com>)

JDO:    Added "trigger" mode for SEQUENCE key generator.
        (Vitaly Shishakov <vitaly.shishakov@novalumen.com>)

JDO:    Added support for MySQL auto_increment columns in IDENTITY key generator
        (Oleg Nitz, thanks to Alain RAVET <aravet@cirb.irisnet.be> for idea
        and to George Stewart <georgestewartiv@yahoo.com> for help).

JDO:    Improved support for BLOB and CLOB values. Now you can get them as
        java.io.InputStream and java.sql.Clob, respectively, see "types.html"
        for details (oleg).

JDO:    Solved problem of NULL dirty checking with Oracle (oleg).

JDO:    Added support for BIGINT sql type in key generators (oleg).

JDO:    Bug fix in the handling of classloader in the mapping loader (reported
        by brian rogers <brian@freya.bianca.com>).

JDO:    Added "serializable" as a supported field type. Require BLOB support in the
        database. (Thomas Yip <yip@intalio.com>)

JDO:    Merged JDO branch, "castorone", into the main branch.

JDO:    Merged: Store cycle during transaction "prepare" state is split into
        preStore and store cycles. With the new addition cycle, dependent object
        using key-generator is stored properly. It also avoid unnecessary update
        SQL statements execution. (Thomas Yip <yip@intalio.com>)

JDO:    Merged: Added markModification in TransactionContext. It enable a
        more flexible way to mark an object dirty. (Thomas Yip <yip@intalio.com>)

JDO:    Merged: RemoveRelated is added in LockEngine. It automatically removes the
        reference of the deleted object in other related object. It protect
        cache consistency and avoid some ObjectNotFoundException due to
        users' errors. (Thomas Yip <yip@intalio.com>)

JDO:    Merged: Added Multiple Primary Keys support. (Thomas Yip <yip@intalio.com>)

JDO:    Merged: Added Many-to-Many relationship support. (Thomas Yip <yip@intalio.com>)

JDO:    Merged: Added Lazy loading for "collection" support. (Thomas Yip <yip@intalio.com>)

JDO:    Merged: Improved dependent object support. (Thomas Yip <yip@intalio.com>)

JDO:    Merged: Improved the in-memory locking architecture and stablity. (Thomas Yip <yip@intalio.com>)

JDO:    Merged: Cleaned up excessive ExceptionImpl classes. (Thomas Yip <yip@intalio.com>)

JDO:    Merged: Support of Object[] as a collection type is temporarily removed.
        (Thomas Yip <yip@intalio.com>)

JDO:    Merged: Support of custom ClassDescriptor for JDO side is no longer supported.
        (Thomas Yip <yip@intalio.com>)

DAX:    Merged: Tempoarily removed DAX. To be reworked and merged into JDO
        (as new type of data-store).  (Thomas Yip <yip@intalio.com>)

DSML:   Add a more detailed policies :
        * NewAttrOnly, which implies that new attributes are created according
        to the DSML, but attributes that already have a value in the ldap are
        not updated;
        * UpdateOnly, which mean that DSML attributes that do not already exist
        in the Ldap are not created.
        Submitted by Marc-Antoine Parent <Marc-Antoine_Parent@Mitel.COM>

DSML:   An ASCII string encoding bug is fixed.
        Submiited by Marc-Antoine Parent <Marc-Antoine_Parent@Mitel.COM>

Version 0.8.11 December, 15 2000
--------------------------------

XML:    Updated Schema syntax and some of the Schema Object Model to support
        the W3C XML Schema Candidate Release. (kvisco)

XML:    Allow the use of uninitialized collection. Castor will instiate a new
        collection of the proper type when necessary.
        (Sebastien Gignoux <gignoux@intalio.com>)

XML:    Added #setResolver method to Marshaller, thanks to George Stewart for
        pointing out to me that I neglected to add this method. (kvisco)

XML:    Changed name of xml element in the mapping.dtd to bind-xml. This change
        won't effect any existing mappings yet, because I've added backward
        compatibility support. (kvisco)

JDO:    For HIGH/LOW key generator the paramater "global" has been added, it gives possibility
        to generate globally unique keys (Oleg Nitz).

JDO:    SAP DB driver, improved support for MySQL (Oleg Nitz)

JDO:    Added possibility to close OQL queries in order to release resources (Oleg Nitz)

Version 0.8.10
--------------

XML:    Made the collection name in the mapping file NOT case sensitive. (Seb)

XML:    Added new validation flag for the marshalling framework in castor.properties
        Changed the parser validation property to og.exolab.castor.parser.validation
        (Arnaud)

XML:    Added fix to Marshaller#isPrimitive to support BigDecimal, submitted
        by Don Kleppinger. (kvisco)

XML:    Added "-nodesc" flag to source generater to disable generation of
        class descriptors. Suggested by George Stewart. (kvisco)

XML:    Fixed a bug in the unmarshalling of array of primitive type when using mapping.
        (Seb <gignoux@intalio.com>)

XML:    Added feature to castorbuilder.properties to allow specifying a super
        class of generated types (kvisco)

Version 0.8.9
-------------


JDO:    SEQUENCE key generator for Interbase (contributed by Nic Wise <nicw@xerxes.co.nz>).

JDO:    MySQL driver (contributed by Leonardo Souza Mario Bueno <leonardo@itera.com.br>).

JDO:    Annoying type conversion problems solved:
        - integer SQL type for Oracle now can be used for dependent objects
          identities - before this caused type conversion error;
        - timestamp SQL type can be used with Sybase - before dirty checking
          failed;
        - Database.load() now accepts identity value of the field type,
          type conversion is performed correctly - before it was needed
          to use the SQL type for Database.load(), but the field type
          for OQLQuery.bind(). (Oleg Nitz)

JDO:    Interbase driver (contributed by Terry Child <tmchild@gmx.net>).

JDO:    Added UUID key generator.
        (contributed by Thomas Fach <thomas.fach@publica.de>)

JDO:    jdoBeforeCreate() callback method has been added to Persistent
        interface. It is called during db.create() just before creating
        object in the persistent storage (Oleg Nitz).

JDO:    InstantDB driver (contributed by I. Burak Ozyurt <bozyurt@san.rr.com>).

JDO:    Replacing of extended object in the cache on load of extending object
        implemented. jdoLoad signature changed. Now in jdoLoad you can request
        reloading the object instance as an instance of an extending class.
        You need some "type" field in the extended class, which determines
        the correct extending class, see example in
        src\examples\myapp\Product.java. (Oleg Nitz)

JDO:    Now IdentityKeyGenerator works with Hypersonic SQL identities
        (idea by Mark Delanoy <mdelanoy@niku.com>)

JDO:    Fixed bugs (contributed by Bill Reynolds <bill@leastsquares.com>)
        - same OID for parent class instance and subclass instance
          with the same identities causes cache corruption
        - it is possible for a subclassed object to be reported as
          non-persistable even if it has a legal mapping
        - if you're using a class with the identity key generators and
          no member fields, you get bad sql generated

JDO:    Added support for LIMIT clause in OQL queries, currently for
        PostrgeSQL only (contributed by Alexey Snisarenko <alex@plesk.com>)

JDO:    Added JDO.setClassLoader(). (Oleg Nitz <on@ibis.odessa.ua>)

JDO:    Fixed problem with Float/BigDecimal and Double/BigDecimal
        type conversions. (Oleg Nitz <on@ibis.odessa.ua>)

JDO:    Implemented algorithm of "bounded" dirty checking for long
        transactions, it uses local timestamps and is works only
        if the object is still in the cache at the end of the transaction.
        See interface TimeStampable and Database.update().
        (Oleg Nitz <on@ibis.odessa.ua>)

JDO:    Changed HIGH/LOW key generator implementation: now holds lock
        on the record in the sequence table until the end of the transaction
        and doesn't use updatable ResultSets. (Oleg Nitz <on@ibis.odessa.ua>)
        Fixed a gap in HIGH/LOW key generator implementation: with databases
        that don't support "SELECT FOR UPDATE" (like Hypersonic SQL and
        InstantDB) it was possible to get the same key values in two concurrent
        transactions (Reported by George Stewart <georgestewartiv@yahoo.com>)
        Now works in a separate connection, and commits changes to the sequence
        table immediately.

JDO:    Temporary fix to ClassLoader problem in EJB environment: application
        classes are loaded using context classloader of the current thread.
        (Oleg Nitz <on@ibis.odessa.ua>)

Misc:   JDK 1.1 compatibility is back. (Oleg Nitz <on@ibis.odessa.ua>)

XML:    Support for Bound Properties

XML:    Added support for Pattern Facet
         - currently works for string, integer, and long
        (kvisco)

XML:    Updated the Schema Object model to support the new Grouping syntax
        - Groups are still not supported by the source code generator.
        (kvisco)

XML:    Updated Unmarshaller to support "empty" strings (kvisco)

XML:    Added support for direct public field access for the Marshalling
        Framework when no accessor methods exist. (kvisco)

XML:    Fixed Marshaller#setMarshalAsDocument so that XML fragment marshalling
        works again. This used to work, but changes to the serializers had
        prevented this from working properly. Reported by Phil Grida. (kvisco)

XML:    Fixed endless recursion bug when processing recursive element
        declarations, reported by Chris Schaefer (kvisco).

XML:    Added George Stewarts changes to give mappings higher priority than
        generated descriptors

XML:    Added Patrick Higgins changes to the javasource package to fix
        support for abstract methods (kvisco)

XML:    Added support for in-lines SimpleTypes (anonymous) for
        attribute declarations (kvisco)

XML:    Added support for in-lined SimpleTypes (anonymous) for
        element declarations. (kvisco)

XML:    Added Luis Arias upgrade for the maxOccurs attribute of elements
        for the April xML Schema draft (kvisco)

XML:    Added support for top-level annotations (kvisco)

XML:    Made some changes in Unmarshalling code to handle "null" primitives.
        Based on suggestions from Fabrice Gomez. (kvisco)

XML:    Fixed a bug when Unmarshalling/Marshalling primitive Object wrappers
        using dynamic-introspection. (kvisco)

XML:    Changed some case-sensitive issues with the below mentioned Schema
        syntax upgrade (kvisco)

XML:    Update of the XML Schema syntax to the April 7th draft
           (Remy Maucherat <remm@apache.org>)

        The following things in the April draft are supported :
          - datatype -> simpleType
          - type -> complexType
          - the "source" attribute has been replaced by "base"
          - the "fixed" attribute in an attribute element now is
            part of the "use" attribute
          - the "default" attribute, which is used to specify the default
            value of an attribute, now is "value"
          - the "minOccurs" attribute of an attribute element has been removed,
            the attribute "use" has to be used instead. "use" can have the
            following values : default, optional, required, fixed and
            prohibited
          - Info element is now Documentation
          - maxOccurs = "*" is replaced by maxOccurs="unbounded"
            (Andrew Fawcett)

XML:    Java 2 types compatibility (Patrick Higgins)

XML:    <include> element support (Andrew Fawcett)

XML:    decimal type support (Andrew Fawcett)

XML:    Support xsi:type from XML Schema for Instances
    (Remy Maucherat <remm@apache.org>)


Version 0.8.8  June 20, 2000
----------------------------

XML:    Added support for the Unmarshaller to automatically determine the
        Class of the root element, based on a given Mapping, or
        ClassDescriptorResolver

XML:    Added support for the "has" method for primitives in the generated source

XML:    Added support for specifying the destination output directory for the
        generated source code

XML:    Added support for fixed attributes, this currently works for string
        or integer values

JDO:    Fixed bug: NULL value in database was read as 0 for Java wrappers
        of primitive types (Long, Integer, etc.), now they are read as "null".
        (Oleg Nitz <on@ibis.odessa.ua>)

JDO:    Changed the inner SELECT syntax in MaxKeyGenerator to make it work
        with Hypersonic SQL.
        (Contributed by Santiago Arriaga <santiago@catnet.com.mx>)

JDO:    Hypersonic SQL driver.
        (Contributed by Santiago Arriaga <santiago.arriaga@catnet.com.mx>)

JDO:    Changed KeyGeneratorFactory interface for better perfomance:
        now the target primary key SQL type is passed to the key generator,
        and no type conversions are performed after the key is generated.
        (Oleg Nitz <on@ibis.odessa.ua>)

JDO:    Added support for attributes of application type and for nested
        attributes. Assume that you have an attribute "balance" of
        applicatation type "Balance" which has methods "getBigDecimal"
        and "setBigDecimal", then you can write in mapping.xml
          <field name="balance.bigDecimal"...
        and Castor will get and set the attribute value as
        getBalance().getBigDecimal() and getBalance().setBigDecimal(value).
        Note, that getBalance() may be null, in this case when setting
        a non-null value Castor will first do setBalance(new Balance()),
        and then getBalance().setBigDecimal(value).
        Another example of usage of the this feature is attribute "address"
        with nested attributes "country", "zipCode", etc.
        These attributes also may be of application type or nested, e.g.
          <field name="address.country.string"...
        (Oleg Nitz <on@ibis.odessa.ua>)

JDO:    Small fix: now fields in mapping.xml may have no "sql" sub-element,
        e.g. the field may be only for XML marshalling, other fields
        may be persisted through JDO. (Oleg Nitz <on@ibis.odessa.ua>)

JDO:    "CALL" OQL queries now work with Oracle stored functions
        returning REF CURSOR (Oleg Nitz <on@ibis.odessa.ua>)
        and PostgreSQL stored functions returning instance
        (contributed by Rostislav Beloff <ros@domainforfree.com>)

JDO:    Added type convertors BigDecimal <-> Boolean
        (contributed by Markus Fritz <mfritz@justis.de>)

JDO:    Fixes multiple request of same object with DBLocked
        (Oleg Nitz and Markus Fritz)

JDO:    Changes to Persistent interface enable developer to use database
        operations inside jdoStore, jdoCreate, jdoRemove.
        (Oleg Nitz <on@ibis.odessa.ua>)

JDO:    Cache control at JDO configuration and mapping file specification -
        no-cache option, cache count limit, cache time limit, LRU removal
        deamon (Thomas Yip <yip@intalio.com>)

JDO:    Bug fix: for created objects fetch() returned oid instead of object
        (contributed by Chris Stevenson <chris@ssabsa.sa.gov.au>)

JDO:    SQL Date types handling is improved.
        (Oleg Nitz <on@ibis.odessa.ua>)

JDO:    Bug fix: small bugs w/ BETWEEN in parser...reported by Vladmir Sekissov.
        (<nissim@panix.com>)

JDO:    fix string conversion to surround with ' and escape internal ' fix for
        bug with like. (<nissim@panix.com>)


Version 0.8.7  June 2, 2000
---------------------------

JDO:    Informix JDBC driver. (Contributed by Santiago Arriaga
        <santiago.arriaga@catnet.com.mx>)

JDO:    SEQUENCE key generator now works with Oracle. It has a special
        RETURNING mode for Oracle8i which is more efficient because
        obtains the identity during INSERT, without any additional SQL queries.
        (Oleg Nitz <on@ibis.odessa.ua>)

JDO:    Added three paramaterized type convertors: Date<->Integer,
        Date<->BigDecimal and Date<->String. The latter uses the SimpleDateFormat
        patterns (e.g. char[MMM d, yyyy]). The others uses similar
        but shortened patterns (e.g. numeric[YMDhmsS], which is equivalent
        to "yyyyMMddhhmmssSSS" SimpleDateFormat pattern).
        (Oleg Nitz <on@ibis.odessa.ua>)

JDO:    Fixes to handling of dependent objects create/delete/modify during
        transaction commit. (Oleg Nitz <on@ibis.odessa.ua>)

JDO:    Added convertor from byte to short/integer. (Contributed by Harindranath P. R. Nair
        <hari.nair@alopa.com>)

XML:    Identity field will now use XML name provided in mapping file.

XML:    Marshaller will now accept both primitive and non-primitive types and apply the
        proper conversion; no dropped in convertor used, so Date/byte conversion should
        work as expected; added test case for type handling of XML. (Bug reported by
        Eitan Suez <eitan@uptodata.com>)

Misc:   Fixed security bug when running as an Applet. (Reported by Remus Pereni
        <remus@nolimits.ro>).

Misc:   Added support for Java 1.2 Collection by running the source generator with the
        option '-types j2'. Vectors are used with 'j1' and ODMG 3.0 DArray with 'odmg'.


Version 0.8.6  May 24, 2000
---------------------------

XML:    Added support in the Marshaller to specify whether or not to marshal
        as an XML document, or just an XML fragment (default). Currently
        the only difference is the XML declaration is printed when marshalling
        as a document. I will add support for specifying the DOCTYPE. Of course
        since a SAX 1.0 DocumentHandler doesn't allow this, DOCTYPE and
        XML declarations will only be printed when a Writer is used.

XML:    Added support in the unmarshaller for better inheritence checking.
        If a FieldDescriptor is not found for an element, an attempt to
        obtain ClassDescriptor will occur for the given element. If found,
        another check will be performed to find a FieldDescriptor that
        describes a field which is a superclass of type described by the
        class descriptor. (see src/tests/xml/Inheritence.java)

JDO:    Added support for paramaterized type convertors. Currently supported is boolean
        to char convertor using T/F character values (e.g. char[01] or char[FT]). More
        convertors and parameter specification will be added in 0.8.7. (Oleg Nitz
        <on@ibis.odessa.ua>)

JDO:    Fixed bug when related object is null and SQL_OTHER type is passed to JDBC
        driver; now properly passes type of identity field. (Reported by
        Eitan Suez <eitan@uptodata.com>).

JDO:    Fixed bug with dirty checking that caused lock to not be acquired and object
        to be deleted if modified, and now properly reporting modified value of object.

JDO:    Fixed the way in which null fields are handled, so has/delete methods are called
        if available, default value is used otherwise, setNull/wasNull are used on the
        JDBC record.

JDO:    Changed callback sequence. jdoRemove is now called on deleted objects,
        unsetDatabase on objects that become transient (including those removes).
        setDatabase is called whenever the object becomes persistent (that is,
        used in a transaction) and passes the database to support lazy loading.

JDO:    Fixed SQLTypes to pick up proper SQL type form field of type java.util.Date.
        Fixed SQLEngine to use SQL type in some calls to setObject.
        (Contributed by Donald Ball <balld@webslingerz.com>)

JDO:    Added quoting to column and table names to support white spaces and keywords
        (Only Postgres, Sybase and SQL Server).

Mapping:    Added a match attribute for the xml element, this is used for allowing
            better inheritence support. Setting this match attribute will restrict,
            or extend the xml names matched by a given XMLFieldDescriptor.

Mapping:    Added resetValue() method to field handler. This generally resets a field to
            it's default value or empties a collection field.

Mapping:    Date type no longer defaults to new date() when field is null, field is no
            longer set to default when null. (Reported by Lincoln Spiteri
            <Lincoln.Spiteri@mobisle.com>)

Mapping:    Fixed mapping loader to complain if get/set methods are not found. Both are
            required to be present, unless a collection field is used which only requires
            a get method. (Reported by Lincoln Spiteri <Lincoln.Spiteri@mobisle.com>)

Mapping:    Added convertor between String and character. (Reported by Donald Ball
            <balld@webslingerz.com>)

Mapping:    To fix problem with compiled class descriptors for XML and mapping file for
            JDO not working together, mapping loading will not attempt to load class
            descriptors. A permanent fix will be included in 0.9 or 1.0.
            (Patiently reported by Andrew Ikon <aikon@niku.com>).

Mapping:    Fixed collection handler to work with arrays of any object type (e.g. strings).


Version 0.8.5  May 12, 2000
---------------------------

JDO:    Remove enumerate collection type. Only get method is required to support
        java.util collections, get/set methods to support arrays. Extended the
        CollectionHandler interface with size() method to assist in validation.

JDO:    Revised the CacheEngine towards dependency support, adding FIFO list to
        determine order of object removal, simplifying the prepare stage. Objects
        will now be removed from the database in the same order they were removed
        by calling Database.remove().

JDO:    Fixes to outer query expressions:
        - JDBCQueryExpression fixed and tested with Access (Christopher
          Elkins <celkins@scardini.com>)
        - OracleQueryExpression fixed not tested with Oracle
          (Sebastien Sahuc <ssahuc@imediation.com>)

JDO:    Now using new OQL parser by default. Added support for is_defined/
        is_undefined (IS NULL), BETWEEN and DISTINCT. (Nissim
         <nissim@panix.com>)

JDO:    Added convertor between java.sql.Date and java.util.Date
        (reported by <Lincoln.Spiteri@mobisle.com>).

JDO:    Improved type convertion for key generators. MAX key generator now
        should work with PostgreSQL. (Oleg Nitz <on@ibis.odessa.ua>)

JDO:    Added support for stored procedures in OQLQuery. Now it is possible to
        create queries of the form "CALL sp_something($) AS myapp.Product",
        where sp_something is a stored procedure returning one or more
        ResultSets with the same sequence of fields as Castor-generated SELECT
        for the OQL query "SELECT p FROM myapp.Product p" (for objects without
        relations the sequence is: identity, then all other fields in the same
        order as in mapping.xml). (Oleg Nitz <on@ibis.odessa.ua>)

XML:    Added some namespace support to the XML Schema reader. It currently doesn't
        properly handle namespace scoping as you go down the tree, so if you are
        changing your namespace declarations for some reason on sub-elements it
        probably won't work properly and you'll need to wait until Monday when I
        finish it up.

XML:    Fixed problem when using attributes that are of enumerated datatypes,
        the types subpackage was not getting imported (reported by markd@lutris.com)

XML:    Fixed problem when using enumerated datatypes with enumeration values
        that contained Java keywords (reported by markd@lutris.com)

XML:    Support for ODMG 3.0 DArray collection in the XML source code generator.
        When running the source code generator with the FieldInfoFactoryODMG30
        collection fields will use org.odmg.DArray as the collection type for
        interoperability with OODBMS using the ODMG 3.0.
        (Contributed by Frank Thelen <frank.thelen@poet.de>)

Misc:   Support for Java 1.2 collections: Collection, Set, Map. Requires Java 1.2
        to compile, but using reflection can be made to work on Java 1.1.


Version 0.8.4  May 5 2000
--------------------------

XML:    Fixed a ClassLoader issue with the ClassDescriptorResolver

XML:    Added validation back into the generator sources

XML:    Added some changes from Frank Thelen to allow subclassing FieldInfoFactory

XML:    Fixed bug that occured when an enumeration uses uppercase values

XML:    Fixed bug with using datatype

JDO:    Where clause now supports:
        - unary operators: +, -, abs, not
        - binary operators: +, -, *, /, mod, ||, LIKE, >, >=, <, <=, =, !=, and,
        - parenthesis: passed through to SQL as in OQL
        - numbered parameters including user specified type support
        (Nissim <nissim@panix.com>)

JDO:    Fixed bug in Database when used as sychronized resource in a J2EE environment.
        Calling close() will not rollback the transaction until the J2EE server has
        completed two-phase commit and notified it. Database must be registerd with
        a JTA transaction manager using the setTransactionManager option.

JDO:    Fixed bug in key generator when using non-primitive value (e.g. Integer, String).
        Previously SQLEngine create was never called, now it is called and object properly
        recorded in transaction.

Mapping:    Fixed bug that caused exception with inheritance, now inheritance works
            correctly if classes are specified in proper order in the mapping file.
            (Oleg Nitz <on@ibis.odessa.ua>)

Tests:  Updated test cases, now includes test cases for key generators.
        (Oleg Nitz <on@ibis.odessa.ua>, Arkin <arkin@exoffice.com>)


Version 0.8.3  April 28, 2000
-----------------------------

JDO:    New OQL query engine. Not used by default, see new methods in OQLQueryImpl
        and package org.exolab.castor.jdo.oql.

JDO:    Added support for null fields by calling the relevant setNull() method
        when setting a null field. Does not apply to query parameters yet, does
        not apply to identity fields.

JDO:    Added key generators support. Implemented four algorithms:
        "MAX" - generic "MAX(pk) + 1" algorithm;
        "HIGH/LOW" - generic "HIGH/LOW" algorithm (extendible);
        "IDENTITY" - "SELECT @@identity" for Sybase and SQL Server;
        "SEQUENCE" - "SELECT nextval('..._seq')" for Oracle and PosgreSQL;

JDO:    Added package org.exolab.castor.jdo.drivers which includes RDBMS specific
        factories, query expressions and key generators. Added factories for DB2,
        and SQL Server.

Misc:   Added support for hasXXX()/deleteXXX() methods to determine if a value
        exists when the value is a primitive (thus, cannot be null). Used by both
        JDO and XML.

Misc:   Fixed null pointer exception with collection handler. Deprecated
        checkValidity on field handler (new validation code from XML will come
        shortly).

JDO:    Added and tested outer joins.

Persist:    Added getIdentity() method to TransactionContext().

Misc:   Modified the test harness to run from an XML test file. Added test case
        for type handling (only null fields at the moment) and outer joins.


Version 0.8.2   April 7, 2000
-----------------------------

JDO:    Added experimental update() method to Database interface.

JDO:    Fixed some minor glitches in support for exclusive and db-locked
        access, documented the available access modes.

JDO:    Fixed synchronization support, disabled checkpoint method.
        Fixed bugs in handling of default field values.

JDO:    Fixed circular exception problem in ObjectLock.release.
        (Contributed by Jason Weistein <jasonw@reticular.com>)

Misc:   Documented the locking options in Castor and concurrency support.
        Added the three locking mode to all the test cases.


Version 0.8.1   April 5, 2000
-----------------------------

XML:    Fixed long->object conversion which suffered from a cut and paste bug
        from the integer type.

XML:    Added back inheritence support inside XMLClassDescriptor,
        which was in MarshalInfo, but removed during the upgrade.

XML:    Fixed bug with creating default XML name in XMLClassDescriptorImpl

XML:    Fixed bug with unmarshalling primitive String types.
           -- reported by Remy Maucherat and Kevin Burton

XML:    Fixed bug with namespace support during marshalling of primitive
        and immutable types

XML:    Added back namespace support, which was temporarily removed during
        the upgrade

JDO:    Added Locked mode to provide locking at the database level, as
        opposed to Exclusive mode which provides locking at the cache
        level. Added support for loading/querying with a given access mode.

JDO:    Improved concurrency for shared mode by eliminating write locks when
        modified field is not marked as dirty.

JDO:    Added isClosed method to database. Deprecated checkpoint.

JDO:    Added preliminary support for controlling cache size and removing
        objects from cache.

JDO:    Fixed bug in bind( String) method of OQLQuery.

JDO:    Fixed bug with modified exception not removing copy from cache.

JDO:    Fixed bug with reusing queries.

Misc:   Upgraded test cases to run inside JTF as a test harness.


Version 0.8     March 27, 2000
------------------------------

XML:    support for IDREF/ID has been added back in

XML:    fixed circular reference bug
          -  This was an indirect bug caused by a bug
             in org.exolab.castor.util.Stack

XML:    fixed bug in method naming when type is "ID"

XML:    Updated the Source code generator to work with new Framework
        - Note I currently removed validation support, this will be
          back ASAP
        - There is a known bug with using "binary" type...I'll have
          this fixed ASAP also

XML:    We are now one step closer to using the mapping files with
        Castor XML. A lot of changes have gone into sharing the "descriptor"
        framework between Castor XML and Castor JDO...I can't enumerate all
        the changes in this log, but here are a few:

        - MarshalInfo and MarshalDescriptor have been changed to
          XMLClassDescriptor, and XMLFieldDescriptor respectively, and the
          interfaces have changed so be careful
        - We added the XMLFieldHandler
        - Changed MarshalInfoResolver to ClassDescriptorResolver

JDO:    Placed the ODMG API in the org.exolab.castor.jdo package,
        to be included in the JavaDocs and to enable the introduction
        of Castor (RDBMS) specific features.

JDO:    Moved transaction handling into the Database interface, queries
        are now created from the Database object, JDO servers at the
        implementation factory.

JDO:    Added preliminary support for many-many relations, improved
        support for one-many relations, fixed bug in isModified with
        relations.

JDO:    Added support for pluggable SQL engines (PersistenceFactory),
        listed in the Castor properties file and referenced from the
        JDO configuration file, allowing each database configuration
        file to select the most suitable engine.

JDO:    Extended JDO configuration file to include engine name, plus
        minor modifications to element and attribute names in DTD/Schema,
        and documentation of the configuration file.

JDO:    Upgraded to use QueryExpression to construct SQL query statements
        in database specific syntax.

JDO:    Implemented dirty checking on objects loaded with a shared lock.
        Dirty checking performed on fields within UPDATE statement requiring
        a single SQL operation to update/check dirtyness.

SPI:    Added QueryExpression and KeyGenerator to the SPI. QueryExpression
        is generated from PersistenceFactory. Added way to load factories
        from the Castor properties file.

Persist:    No longer supports identity changes.

Persist:    Rollback of transaction no longer reverts object to their previous
            state due to lock race condition that hampers efficiency. Eliminating
            this feature improves concurrency with optimistic locks.

Misc:   Documentation distribution includes API JavaDocs and JavaDocs for
        all Java classes. Tarball/zip include just the API JavaDocs.
        Web site has been revised accordingly and some links moved around.

Misc:   Updated build.xml file now includes documentation in tarball and
        zip, builds both API JavaDocs and all classes JavaDocs, and does
        not include package.html files in JARs.


Version 0.7.11  March 10, 2000
------------------------------

JDO:     Added support for one-many relations using the new mapping/persist
         mechanisms. Retains support for one-one relations.

Mapping: Introduced CollectionHandler and support for collection fields
         (for one-one and one-many relations), with support for three basic
         collection types: vectors, hashtable, and arrays.

Persist: Added support for attached and non attached relations, singular and
         multi, in both query and commit phase. Required new algorithm for
         preparing the transaction to commit.

Persist: Fixed bug in ObjectLock that could lead to deadlock detection when
         there are more than two threads competing for the same object.
         (contributed by Jim Alateras)

Misc:    Updated build.xml file now builds docs tarball, and builds source
         tarball/zip for expansion with a castor-x.x directory (contributed
         by Kevin Burton)

Examples: Upgraded the JDO example to produce XML output of the query results
         using a Marshaller and the Xerces Serializer.

Examples: Example of XML-Servlet using JDO to load products from the database,
         XML to fire SAX events and the XML-Servlet to apply XSLT transformation
         and produce the HTML page.


Version 0.7.10  March 3, 2000
-----------------------------

JDO:    Upgraded to use new cache mechanism, reducing memory overhead for
        loading. Initial code base for one-many relation support.

Persist: Optimization to the cache mechanism. Now uses fixed-size arrays to
         hold cached objects, eliminating much of the use of handlers.
         Also cleaned some of the API calls.

Persist: The cache mechanism now supports class-level resolution, allowing
         different cache properties for different class types.

Persist: Added initial support for one-many relations. Currently not working,
         but the query engine has been revised to deal with one-many
         relations, and some tests have been working successfully.

Persist: Query mechanism no longer supports scrolling to a particular point,
         due to the need to efficiently retrieve related records.

Mapping: Minor changes to accomodate better creation of relation handlers.


Version 0.7.9  February 25, 2000
--------------------------------

JDO:    Now loads JDO configuration file from ODMG.loadDatabase() which in
        turn loads all the required mapping files. Added jdo-conf DTD which
        has been separated from the mapping DTD. For more info see the JDO
        example.

JDO:    Supports the new mapping API, new mapping DTD. See the JDO example
        for using the new mapping file.

JDO:    Cleaned up SQLEngine query composer using QueryExpr. Will be able to
        support different join and locking syntaxes in the future.

JDO:    Access mode (shared, exclusive, read-only) is now specified at the
        class level in the mapping file and not in the database level as
        before. This allows one transaction to support multiple type of
        locks depending on the object being used.

XML:    A Castor JAR with just the XML module will be created from the
        'jar' target (less than half the size) and also available from
        the FTP.

XML:    Better error reporting in exceptions.

Mapping:    The API for the mapping package has been finalized. Both JDO and DAX
            use the new API, XML support is in the works.

Persist:    Added support for relations (one-one, one-many) in loading,
            creating and deleting of objects. Related objects are now loaded
            from the cache, reloaded only when necessary, locked appropriately.

Misc:   New Ant and build.xml include 100% Java Tar task, improved Javadoc
        task, now also generates zips for binary and source distribution,
        new cvs task gets last snapshot from CVS.


Version 0.7.8  February 10, 2000
--------------------------------

XML:    If annotations are used within elements, or attributes, I add
        these to the Javadoc comments of the generated source.
        example:
        <attribute name="foo" type="string">
           <annotation>
              <info>This comment will be included in the Java source</info>
           </annotation>
        </attribute>

JDO:    Fixed bug in SQLEngine not deleting row. (Contributed by
        Oleg Nitz)

JDO:    Fixed examples not setting reference of related class for
        Inventory (Contributed by Steve Muench)

XML:    Fixed bug with package name for top-level types, reported by
        Kevin Burton

XML:    Added support for "annotation" as a child for most of the structures.

XML:    Added more support for "datatype"


Version 0.7.7  February 4, 2000
-------------------------------

XML:     Changed "archetype" to "type" in accordance with the 19991217
         XML Schema draft

XML:     Added support for "datatype"

XML:     Fixed a bug with the Base64 encoder which caused it to throw an
         ArrayIndexOutOfBounds exception when it recieved a zero-length array

JDO:     Test for duplicate primary key only if select operation failed
         using either the SQL state (X/Open error code) or by running a
         separate select statement. (Contributed by Oleg Nitz)

Persist: Added scrolling capability to QueryResult and PersistenceQuery
         allowing more efficient collection implementation on top of JDBC
         drivers that support cursors. (Idea by Oleg Nitz)

Persist: Application level APIs now deal with PersistenceEngine and not
         with CacheEngine directly. All classes that extended CacheEngine
         have been eliminated.

Persist: Added an SPI package that defines interfaces for Castor
         service providers (i.e. persistence implementations).

Persist: Added support for XA transactions through an XAResouceImpl that
         manages transaction context creation and association. Interface
         initially used in DAX.

Misc:    New verion of Xerces (1.0.2+) and XSL:P included in this build.
         The Xerces update fixes several HTML printing problems, the XSL:P
         build included in this release is 4x faster.


Version 0.7.6  February 2, 2000
-------------------------------

DAX:    First appearance of the DAX implementation based on the Mozilla
        Directory SDK, using the persistence cache engine and the new
        mapping DTD.

Mapping: The mapping package has been upgraded to the new mapping DTD,
         and gained an XML sub-package that can be used to serialize
         mapping information. MappingResolver and MappingHelper are used
         to convert mapping files into descriptors.

Mapping: Added type strings (array of String) and big-integer
         (java.math.BigInteger).

Docs:   Contents of readme file and changelog are now available from the
        HTML documentation.


Version 0.7.5  January 28, 2000
-------------------------------

JDO:    Finalized the transaction and locking semantics and started working
        on a document describing it. I would like to thank Chris Raber of
        GemStone for validating some of the design choices.

JDO:    SQLEngine now employs two schemes for detecting duplicate primary
        keys. For some databases it will use a separate SELECT statement,
        for those that properly return an SQL error it will use the X/Open
        error code (contributed by Oleg Nitz).

JDO:    Dirty check mechanism has been disabled since 0.7.4, although
        the new API enables any number of approaches. The dirty check
        mechanisms will be re-introduced in 0.7.6.

JDO:    Duplicate keys are now only detected inside a transaction, unless
        a similar object is locked by another transaction, fixing a
        potential problem in duplicate key reporting when object is
        removed from persistence storage directly.

Persist: Fixed deadlock detection algorithm. Previous algorithm would
         allow the second transaction to commit but rollback the first
         one. New algorithm allows first transaction to complete, but
         detects deadlock in second one and terminates it.

CMP:    No CMP engine yet, but the design architecture has been reviewed
        by RMH and supports the proper CMP semantics. Still need to
        determine how to deal with out-of-transaction methods. New
        architecture allows Castor to be used as CMP or BMP implementation.

Docs:   Finally there. Added an Ant taskdef (style) and a task (doc) to
        produce documenation in build/doc and the doc JAR. Sources are
        XML, output is HTML, magic is XSLT.

Docs:   Added document describing persistence architecture and started
        working on document describing transaction and locking semantics.

Misc:   The examples have been broken to two packages: examples will contain
        brief and illustrative code showing how to develop with Castor,
        while tests will contain unit tests.


Version 0.7.4  January 23, 2000
-------------------------------

JDO:    New persistence engine. JDO package is now an ODMG API
        implementation on top of the concurrency engine and an SQL 92
        connector.

JDO:    New query mechanism allows multiple objects to be retrieved as
        an enumeration.

JDO:    Revised concurrency engine with query mechanism, object caching,
        transactions and locking, now resides in package
        org.exolab.castor.persist.

JDO:    Added SQL type conversion. A field mapping may now specify the
        SQL datatype using SQL names (numeric, varchar, etc). If the SQL
        type differs than the Java field type automatic conversion will
        apply. Convertors are provided for short/int/long, float/double,
        string, character/byte array, date and BigDecimal.

JDO:    Added dirty check attribute to field mapping. Fields that are
        marked for dirty check will be checked against the database to
        prevent concurrent updates. A concurrent update attempt will
        cause the transaction to rollback. When acquiring an exclusive
        lock at the beginning of the transaction no dirty checking
        occurs.

XML:    Added support for positive-integer and negative-integer
        (Source Generator)

XML:    Added support for Validation during Unmarshalling. Enabled by
        default.  (Marshalling Framework)

XML:    Changed Exceptions from SAXException and IOException to
        MarshalException and ValidationException (Framework + Source
        Generator) -- Sorry for the inconvenience.

Docs:   This is the first release to see some documentation beyond the
        README file. The docs are located in the directory src/doc in XML
        and are transformed into HTML in the target directory build/doc.
        The transformation stylesheets are contained in src/doc/style.

Misc:   Three layer persistence architecture introduced in this release.
        Each package implements the top level applications API (EJB,
        ODMG, DAX, JNDI), org.exolab.castor.persist implements the
        concurrency layer (transaction, locking, caching) and connectors
        are used to talk to the underlying persistent storage.

Misc:   ObjectDesc, FieldDesc and related classed have no been
        consolidated from the three modules and placed in a single
        package org.exolab.castor.mapping.

Misc:   FieldDesc adds required flag and readable/writeable flag.
        ObjectDesc adds key field (formerly JDO primary key) that is
        used across all the modules.

Misc:   Type conversion errors are now reported more accurately before,
        and a type conversion mechanism is being concieved.


Version 0.7.2  January 12, 2000
-------------------------------

JDO:    Implemented object caching. Each transaction gets a single view
        of the object and may change that object without affecting the
        other transaction. Upon commit the shared view is updated. If the
        transaction is aborted, the object is returned to its original
        state.

JDO:    Implemented two phase commit through the XAResource interface,
        allow Castor to perform a prepare stage followed by a separate
        commit stage. Improved the design of the checkpoint method.

JDO:    Now implements the XAResource interface and can be used as
        an XA resource in a JTA/JTS transaction server.

Misc:   Changed location of properties file to fix class name mismatch
        bug. Added example sources to the tar ball distribution.
        Rechecked the libraries to prevent build issues.


Version 0.7.1  January 11, 2000
-------------------------------

DAX:    First release of some DAX code

JDO:    Temporary fix to rollback of objects in lieu of missing
        CacheEngine (JDO)

JDO:    Perliminary code for XAResource support in Castor JDO

XML:    Added some support for derived archetypes (types)
        - only extension derivation is possible at this time,
         so deriveBy must be "extension".

XML:    Added binary, and boolean types to the source code generator
        for Castor XML
        - binary types will be mapped to byte[] by default, and will
          be Base64 encoded and decoded automatically
        - boolean type is an enumeration of "true" or "false"

XML:    Added support for byte[] -> encoding and decoding from Base64


Version 0.7  January 7, 2000
----------------------------

- First release of Castor JDO (Java Data Objects) supporting the
  ODMG API for object persistence over RDBMS.

- Changed MarshalDescriptor to better hide the reflection
  - uses #setValue, #getValue, instead of #getReadMethod, #getWriteMethod

- Changed the way validation is handled, added numerous
  validation related classes to org.exolab.castor.xml .

- Fixed bug with using primitives as PCDATA content of elements.

- Added timeInstant, NMToken and NCName types

=======


Version 0.6  December 20, 1999
------------------------------

- Marshaller package name changed to org.exolab.castor.xml
  (was org.exolab.xml.marshal).

- DSML implementation supporting JNDI and Mozilla Directory SDK.
  Importer/exporter sets for both directory APIs and XML-based
  search and import descriptors.

- Added configuration file support (castor.properties) specifying
  parser and serializer to use and default modes of operation.

- Change build environment to Ant.
