cache2k version 0.20 release notes

Possible breakages

JMX support was removed from cache2k-core module. For JMX support add the dependency cache2k-ee instead.
An expiry time span of 0 (e.g. CacheConfig.setExpirySeconds) switches off caching. It is not possible to override this with and entry specific time calculation.
Interface MutableEntry removed. This was currently unused anyways.
Interface CacheBulkSource removed. This was currently unused anyways.

no more external dependencies
android support: cache2k-api and cache2k-core is compatible with Java 1.6 and android. Extra features needed in enterprise environments separated to module cache2k-ee.
Revised interface to control entry specific expiry (EntryExpiryCalculator)
Configuration / tunable properties
Support sharp timing/expiry
Bulk API fixes and defined exception handling
General infrastructure for off heap caching and persistence (alpha state)
Provide a iterator for all cache entries. Iterator supports full concurrency
Simple logging infrastructure
