-- **Optional Index in Multivalue Columnar Index** For mostly empty multivalued indices there was a large overhead during creation when iterating all docids (merge case). This is alleviated by placing an optional index in the multivalued index to mark documents that have values. This will slightly increase space and access time. [#2439](https://github.com/quickwit-oss/tantivy/pull/2439)(@PSeitz)
+- **RegexPhraseQuery** 
+`RegexPhraseQuery` supports phrase queries with regex. E.g. query "b.* b.* wolf" matches "big bad wolf". Slop is supported as well: "b.* wolf"~2 matches "big bad wolf" [#2516](https://github.com/quickwit-oss/tantivy/pull/2516)(@PSeitz)
