- Blob v2 writes now use the Managed blob kind (lance#9293), so the refresh blob layout test expects Managed instead of Dedicated/Packed. - Datasets with managed blobs set a reader flag that pylance 9.0.0 rejects; pin the tests extra to pylance 14.0.0b7 (fury index). - MultiMatchQuery JSON now includes per-leaf match_queries (lance#9753). - fast_search no longer adds _rowid to the projection (lance#9699).
