Please see the 3.5.2 milestone page for the complete list of changes.

Bug fixes:

• keyProperty specified with parameter name could cause ExecutorException. #1485
• False positive error 'Ambiguous collection type ...' . #1472
• EnumTypeHandler is not used when the enum has methods. #1489
• Auto-mapping fails in a result map referenced from a constructor arg with columnPrefix. #1496

There is a backward incompatible change.

Note that there are some backward incompatible changes since the last release 3.4.6.

• Specifying keyProperty is now mandatory when using useGeneratedKeys. If you relied on the implicit default value (="id"), generated keys will be silently ignored. #1198

• Add resource path to the exception message when parsing XML mapper failed. #1172

Bug fixes:

• Registering type handler against HashMap causes ClassCastException. #1089
• Unable to register TypeHandler once TypeHandlerRegistry.hasTypeHandler is called. #1177
• Serializing and deserializing cached objects causes NullPointerException. #1084
• Invalid error message 'Two methods with same method signature but not providing classes assignable?' in System.err. #929

There should be no backward incompatible change since 3.4.5. Follow this link to see the full list of changes.

Bug fixes:

• The type handler registered for a common interface of enums was not applied correctly. #976
• Lazy loading should not overwrite a property value set by user. #988
• Prevent foreach xml tag from polluting the global context. #966
