Changelog

[0.95] - 2026-07-31

requires collocatordb >= 1.5.0, which fixes the leaks in the collocator lookup, 3.6 kB per uncached collocator request, and builds against the rocksdb of the distribution
CI and docker image install the rocksdb package instead of building rocksdb 5.11 from source

fixed a crash on out of range word ranks: a single request with a w parameter beyond the vocabulary size, or a getVecsByRanks request with such a rank, killed the worker process
fixed w2v.merge, which died at startup with "Undefined subroutine &main::mergeVectors", and the lookup of count based collocators and precomputed profiles for merged models, which used unshifted ranks
fixed getVecsByRanks, which answered every request with "Undefined subroutine &main::getVecs", so the collocator SOM never got its vectors, and which was only reachable below the /derekovecs prefix
fixed memory leaks in the request path: per request the server leaked the target sum array, the thread handles, the target word list and the collocator results of all window threads, plus every string and array returned from C to perl (Inline::C copies those but never frees them)
the result caches are size limited now and configurable via the new cache configuration section; the neighbourhood cache never hit before because lookup and store used different keys
added w2v.compare_to configuration option to configure a derekovecs instance to compare results to (currently only count-based LogDice-delta supported)
