Not using Lucene at the moment, but the changelog doesn't seem to include any breaking changes, only good improvements as you mentioned. I had a look at their JIRA sorting by updated, and found no regressions recently posted there
https://issues.apache.org/jira/projects/LUCENE/issues/LUCENE-10665?filter=allissues&orderby=updated+DESC%2C+priority+DESC Also had a look at the commits between these two versions and found nothing that appears to be a blocker for upgrading. https://github.com/apache/lucene/compare/releases/lucene/9.4.2...releases/lucene/9.5.0 +1 from me Thanks!
