Review Comment: I manually checked that Lucene 9.1.0 reads the vector index created by Lucene 9.0 (with `lucene-backward-codecs` jar). Coming 9.2.0 reads the vectors written by 9.0 and 9.1 as well. We keep all codecs in the same and the previous major version in backward-codecs, there is no need to care about the file format backward compatibility in an older but same major version from the users' perspective (Solr maintainers would properly add the dependency on backward-codecs module). -- This is an automated message from the Apache Git Service.
