GoKawiilManticore Search 27.1.5 has been released. This release brings built-in authentication and authorization, sharded tables, conversational search, faster HNSW builds, better faceting and aggregations, and a long list of fixes across KNN, replication, protocol compatibility and other areas.
This post is a catch-up for everything shipped from 25.0.1 through 27.1.5.
Upgrade Notes
Please review these before upgrading:
27.0.0 adds built-in auth/authz, and enabling it changes access assumptions. Auth is not enabled by default, but once you enable it, anonymous access no longer works. Roll it out in stages: upgrade remote agents and replication peers first, then upgrade the masters that query or manage them, and enable auth only after the whole topology is on the new version. Distributed remote-agent and replication-related operations also need matching stored auth data across the participating daemons. A successful JOIN CLUSTER replaces the joining node's local auth data with the donor cluster's auth data. (Issue #2833 , PR #3648 )

Incoming replicated tables now live under the normal data_dir/<table> layout instead of the cluster path . If you run replication clusters with a custom path , you may need to move or re-synchronize replicated tables after upgrade. Downgrade is only safe before the new layout is adopted. (Issue #4431 , PR #4598 )

(Issue #4431 , PR #4598 ) If you manage MCL separately from the daemon, upgrade it together with Manticore. This release line moves through several MCL updates, from vector-performance work to multithreaded HNSW builds and later stability fixes. Mixing an older library with a newer daemon is not recommended. (25.2.0 , 25.15.0 , 26.0.3 , 26.3.2 , 27.1.0 )
Highlights
Built-in authentication and authorization
Manticore now supports users, passwords, bearer tokens, and fine-grained permissions across MySQL, HTTP/HTTPS, distributed remote agents, and replication-related operations. This makes access control a first-class part of the product instead of something that always has to be handled outside the database.
