11 June 2007: ehcache-1.3 released

The next major version of ehcache has been released.

This version contains the following major new features over 1.2.4:

• A draft JCache API (JSR107) package.
• JMX instrumentation. Register a variety of MBeans from your ehcache instance with your MBeanServer of choice. Care has been taken to make this implementation friendly to a wide variety of JMX NMSs.

  In terms of minor features:

• A new cache attribute, diskSpoolBufferSizeMB, can be set to control the amount of memory that can be used for spooling to DiskStore
• The ehcache shutdown hook is now off by default. Ehcache is typically used in scenarios where someone else has a shutdown hook. It can be re-enabled by setting net.sf.ehcache.enableShutdownHook=true

  The distributed caching feature of ehcache is now in wide-spread use in wide ranging environments. All of this field experience unearthed the need for further documentation, clarificationa and bug fixes, particularly for dirty or mis-configured networks, which have been provided in 1.3. Excellent performance has been reported for clusters with up to 20 nodes.

  A new Tomcat chapter in the documentation provides specific information on configuring Tomcat with ehcache.

  See the changelog for complete details.

  Work on new features will now start on a new 1.4 branch. See the Roadmap for details. 1.3 will be maintained as the new stable branch.
