mybatis-3.4.0

MyBatis 3.4.0 with the following main features:

• New Cursor List method in SqlSession.
• Inherit Spring timeout in transactions.
• Better support for generic types.
• Out-of-the-box support new Date and Time API (JSR-310) classes added in Java 8.

Note that there are changes that may break existing code.

• New method getTimeout() in the Transaction interface. If you implemented your own transaction adapter you will need to implement this method at least with a "return null"
• @options( flushCache ) now takes enum values (DEFAULT/TRUE/FALSE) instead of boolean.
• StatementHandler#prepare(Connection) has been changed to StatementHandler#prepare(Connection,Integer) given that now it gets the transaction timeout.
• SqlSession#selectCursor, Executor#queryCursor, ResultSetHandler#handleCursorResultSets and StatementHandler#queryCursor added. You will need to implement methods if you implemented those interfaces already.

mybatis-3.3.1

The first bug fix release for the 3.3.x branch.

See the details at https://github.com/mybatis/mybatis-3/issues?q=milestone%3A3.3.1

mybatis-3.3.0

Includes two main changes:

• Ognl has been upgraded to 3.0.11 that is the latest version
• The default proxy tool is now Javassist and is included inside the mybatis jar

There are some other minor changes and bug fixes. See the details at https://github.com/mybatis/mybatis-3/issues?q=milestone%3A3.3.0

Note that you can still use CGLIB as the proxy factory tool by adding CGLIB to your classpath and setting the MyBatis global parameter as follows:

<settings>
    <setting name="proxyFactory" value="CGLIB"/>
</settings>

mybatis-3.2.8

See the details at https://github.com/mybatis/mybatis-3/issues?q=milestone%3A3.2.8

Yet another bug fix release. Provides 8 minor bug fixes.

mybatis-3.2.7

See the details at https://github.com/mybatis/mybatis-3/issues?milestone=8&state=closed

This release is a hotfix to solve the bug reported in #167 that broke the @one annotation in 3.2.6.

mybatis-3.2.6

See the details at https://github.com/mybatis/mybatis-3/issues?milestone=6&page=1&state=closed

Provides some new features:

• Caches nested selects
• Lazy loading can be enabled only for specific relations
• Supports returning multiple fields in a select key
• Some other minor improvements

A note for users who implemented their own caches or 3rd party cache adapters. MyBatis no longer calls Cache#getReadWriteLock(). Any locking needed by the cache should be implemented internally by the cache. So in case you coded your own cache make sure it is properly synchronized. See issue #159.

mybatis-3.2.5

See the details at https://github.com/mybatis/mybatis-3/issues?milestone=5&page=1&state=closed

Provides 7 bug fixes, 4 of them are regressions coming from 3.2.3 and 3.2.4.
