SereneDB v26.05.4 adds FTS Highlight functionality and column-store indexing for inverted indexes. The release also fixes view-backed index loading on startup and improves ANN/FTS scan snapshot management.

Why it matters: Full-text search gains highlight support; inverted indexes now support column storage. Fixes view-backed index loading and ANN/FTS scan snapshots. Test in dev; upgrade if using search features.
