v0.6.0

API Changes:

• Added a new option, UseEntryPool, to the builder, which defaults to false. Enabling this option will reuse evicted entries through a sync pool. The sync pool was used by default before v0.6.0 and could not be turned off; but it only benefits systems optimized for allocation and those with heavy concurrent writes. See the README for more details.

Enhancements:

• Theine now uses a single LRU window as the "W" part of W-TinyLFU, adaptively changing its size based on hit ratio. This approach is consistent with Caffeine and should improve hit ratios across various workloads.

v0.5.0

API Changes:

• The NVM secondary cache has been moved to a separate package: https://github.com/Yiling-J/theine-nvm.

Enhancements:

• Reduced Set allocations, making Theine zero allocation (amortized).
• Improved read performance slightly by utilizing a cached now value.
• Fixed race conditions in cost (weight) updates that could cause inaccurate policy cost.
• Added benchmarks for different GOMAXPROC values in the README.
