We’re happy to announce the patch release of Siren Federate version 38.0 for Elasticsearch 8.18.6. This release includes the following improvements and bug fixes:

Improvements

- Upgraded to Elasticsearch 8.18.6. - Added a `siren_dls` query to be used by Investigate to segregate data.
- Improved the `can_match` action to avoid serializing aggregations.
- Improved the `fingerprint` and `can_match` actions to minimize the number of shards processed.

Bug Fixes

- Fixed the `federate_object` runtime field data type when projecting multiple values.
- Fixed unhandled CompletableFuture failures when the fingerprint encountered shard failures.
- Fixed an error in calculating the hash of large queries in AQP requests.
