NHibernate

File Release Notes and Changelog

Release Name: 2.1.0Alpha3

Notes:
** Known BREAKING CHANGES from NH2.0.xGA to NH2.1.0
	##### Run time #####
		* If you want work using lazy loading with LinFu.DynamicProxy now you must deploy NHibernate.ByteCode.LinFu.dll
		* If you want work using lazy loading with Castle.DynamicProxy2 now you must deploy NHibernate.ByteCode.Castle.dll
		* If you want work using lazy loading with Spring.Aop now you must deploy NHibernate.ByteCode.Spring.dll
		* compatible only with .NET2.0 SP1 or above (System.DateTimeOffset)
		* In SchemaExport.Execute the parameter "format" was removed; (NH-1701) enabled configuration property format_sql (default true)
		* Antlr3.Runtime.dll is required
		* the syntax foo.bar.baz.elements or foo.bar.baz.indices is not longer supported.  Use the alternative syntax of elements(foo.bar.baz) or indices(foo.bar.baz) instead
			Note: in some case, where a sub-select is needed, the collection is enough example: FROM m IN CLASS Master WHERE NOT EXISTS( FROM m.Details d WHERE NOT d.I=5 )

	##### Possible Breaking Changes #####
		* ISession interface has additional methods
		* ICriteria.SetProjection now takes a params array of projections, instead of a single projection
			Only a breaking change if you are implementing ICriteria, there is full source code compatability
		* IStatelessSession interface has additional methods
		* DefaultProxyFactoryFactory removed
		* IProxyFactoryFactory now provide the IProxyValidator implementation
		* Now filters are working even with many-to-one association for Criteria and HQL (NH-1293, NH-1179)

	##### Initialization time #####
		* The ProxyValidator check for "internal virtual" (to be intercepted by proxy need "protected internal virtual")
		* The session-factory configuration property "proxyfactory.factory_class" is mandatory; You must choose one of the availables NHibernate.ByteCode

	##### Breaking Changes #####
		* see NH-1633 if you are using SQL native queries
		* CriteriaUtil is gone. NHibernate.Transform.Transformers now returns predefined IResultTransformer.
		* ISessionFactory.Settings is gone (moved to ISessionFactoryImplementor.Settings)
		* Obsolete ORACLE dialects was removed (new implementations are available)
		* ISQLExceptionConverter was changed in order to have more flexibility about information available for the conversion and followed management.
		* ADOException now use string instead SqlString
