 Release Notes
 =============
 
+NixOS 25.05
+-----------
+
+- Switch to the more efficient `fts-flatcurve` indexer for full text search
+  (`merge request <https://gitlab.com/simple-nixos-mailserver/nixos-mailserver/-/merge_requests/361>`__).
+  This makes use of a new index, which will be automatically re-generated the
+  next time a folder is searched.
+  The operation is now quick enough to be performed "just-in-time".
+  Alternatively, all indices can be immediately re-generated for all users and
+  folders by running
+  `doveadm fts rescan -u '*' && doveadm index -u '*' -q '*'`.
+  The previous index (which is not automatically discarded to allow rollbacks)
+  can be cleaned up by removing all the `xapian-indexes` directories within
+  `mailserver.indexDir`.
+
 NixOS 24.11
