What's New in This Release: [ read full changelog ]
· Ease of use. Tuning cache sizes is now as simple as setting the maximum number of bytes. No more setting maximum entry counts and juggling eviction parameters to approximate the maximum amount of system memory your cache can use.
· Greater efficiency. Ehcache now efficiently manages caches based on their memory footprint and can dynamically balance their resource use based on runtime size information.
