Manticore Search 28.4.4 has been released. This release brings faster KNN rescoring, more flexible conversational search, a simpler install and upgrade path, better faceting controls, per-table relevance defaults, and fixes across authentication, replication, SQL compatibility, distributed queries, and columnar/KNN internals.
This post is a catch-up for everything shipped from 27.2.0 through 28.4.4.
Upgrade Notes
Please review these before upgrading:
28.0.0 bumps the plugin ABI version SPH_UDF_VERSION to 12. External UDF, ranker, and token-filter plugin binaries must be rebuilt before loading them into this version. The change lets token-filter plugins receive long dict=keywords_32k tokens instead of silently bypassing values above the old 126-byte plugin limit. Existing table data and configuration remain compatible, and no index migration is required. Downgrade is possible if you also restore plugin binaries built for the older ABI and do not rely on the new long-token plugin behavior. (Issue #4667, PR #4668)
