We just published Hibernate Search 5.10.5.Final, a bugfix release for the 5.10 branch.
HSEARCH-3407: When using the Elasticsearch integration, multi-valued boolean fields used to only take the very first value into account. This is no longer the case, all values are properly indexed.
The other changes are mainly related to our build process.
For a full list of changes since the previous releases, please see the release notes.
All details are available and up to date on the dedicated page on hibernate.org.
