* noticed and fixed obscure piece of nonthreadsafe code outside of core persistence engine
* removed unnecessary drop constraints for some dialects
* MUCH more comprehensive test suite
* changed some terminology used in documentation

* commented the mapping DTD
Changes in version 0.9.5 (8.2.2002)
-----------------------------------
* supports HypersonicSQL (dialect contributed by Phillip Baird)
* supports Microsoft SQL server (with third party JDBC driver)
* proper command-line tool for schema generation and export
* deprecated the interface cirrus.hibernate.Persistent (due to popular demand)
* changes to hibernate-mapping DTD (required to support optional Persistent interface):
- deprecated <property type="package.PersistentClassName"/> in favor of <many-to-one class="package.PersistentClassName"/>
- deprecated <element type="package.PersistentClassName"/> in favor of <many-to-many class="package.PersistentClassName"/>
- deprecated <property role="..."/> in favor of <collection role="..."/>
- deprecated <element role=".."/> in favor of <subcollection role="..."/>
- deprecated <association> in favor of <one-to-many>
* class attribute optional in <component> and <composite-id> tags (determined by reflection)
* querying components of components now supported
* one-shot table creation (no use of unportable "alter table")
* time dataype support
* reflective mappings of java.sql.Time, java.sql.Timestamp, java.sql.Date
* fixed error msg thrown when class is missing a method but has a superclass
* property names now conform to JavaBean spec ("foo" instead of "Foo"). Note that "Foo" still works
* constructors of persistent classes may now be non-public
* collection indexes now mapped to not-null columns
* fixed obscure bug with querying collections inside components of components
* fixed potential bug related to cacheing of compiled queries
* major rewrite of code relating to O-R mappings
* Session.copy() and Session.equals() as convenience for users
* fixed repeated invocations of hasNext() on iterator + iterators now always work with distinct SQL resultsets
* McKoi dialect was contributed by Gabe Hicks
Changes in version 0.9.4 (29.1.2002)
------------------------------------
* fixed BAD bug where XML parsing would not work for parsers other than Xerces - thanks to Christian Winkler
* added some more assertions to catch user "mistakes" like changing ids or reusing existing ids
Changes in version 0.9.3 (27.1.2002)
------------------------------------
* repackaged (corrupted DatasourceConnectionProvider.class)
* better exception reporting using datasource
* added Datastore.storeClass() which looks for mapping file in classpath (class foo.Bar -> foo/Bar.hbm.xml)
* improved documentation
Changes in version 0.9.2 (25.1.2002)
------------------------------------
* iterate over query results (lazy instantiation of query results)
* added "select foo, bar" style queries returning multiple objects per row
* delete by query
* composite key support
* outer joins for faster (?) loading of associated objects ( set "hibernate.use_outer_join" to "true" )
* connection pooling when using DriverManager
* foreign key constraint from unkeyed collection table to owner entity table
* improved drop tables script execution (still not infallible)
* added <composite-element> tag
* added not-null properties and elements
* added an optimisation for dates and components
* made some XML attributes optional
* fixed errors in documentation + documented some extra features
