Please see the 3.5.0 milestone page for the complete list of changes.

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
• Using Cursor now requires a driver that supports JDBC 4.1 API. #1351
• If you extended org.apache.ibatis.type.BaseTypeHandler, you might need to add wasNull() check in your type handler. #1144
• The default resultSetType value has been changed from FORWARD_ONLY to UNSET. This is applied only to annotation based mappers (for XML based mappers, the default is/was UNSET). #1334
• If you extended org.apache.ibatis.transaction.jdbc.JdbcTransaction for some reason, the property autoCommmit has been renamed to autoCommit. #941
