cache2k version 0.20 release notes
- 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.
New and Noteworthy
- 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
- Optimized cache configuration. The builder can now build the cache or just a configuration object
