This release includes API incompatible changes.

Highlights

• Java 11 or above is required
• Java 8 users can continue to use version 2.x, which will be supported

API improvements

• Added Policy.refreshes() for a snapshot of the in-flight refresh operations
• CacheLoader and AsyncCacheLoader offer bulk factory methods
• AsyncCacheLoader methods may now throw checked exceptions
• Better usage of Checker Framework nullness annotations (#​337)
• LoadingCache.refresh now returns the in-flight future (#​143)
• Various unimplemented default methods are now abstract
• Added LoadingCache.refreshAll convenience method
• Bulk loads now receive a Set of keys (was Iterable)
• More flexible generic bounds and type parameters

Implementation improvements

• Refresh operations ignore redundant calls during an in-flight load and are linearizable (#​193, #​236, #​282, #​322, #​373, #​467)
• The Java Platform Logging API is used instead of java.util.logging (#​456)
• sun.misc.Unsafe is no longer required (#​273)

Incompatible changes

• VarExpiration time-based puts now return the old value instead of a boolean result
• Removed jandex resource as no longer utilized by Quarkus
• Split Policy.Expiration into fixed and refresh interfaces

Deprecation removals

• CacheWriter, SingleConsumerQueue, and UnsafeAccess
• StatsCounter.recordEviction variations
• CacheStats constructors

Notes

• CacheWriter usages can be replaced by Map computations and Caffeine.evictionListener
• For best performance Unsafe may be used if available, otherwise falls back to VarHandles
• We will continue to support and maintain version 2.x for Java 8 users
