------------------------------------
Summary: Bump FST Version
Key: LUCENE-8844
URL: https://issues.apache.org/jira/browse/LUCENE-8844
Project: Lucene - Core
Issue Type: Bug
Reporter: Mike Sokolov
In LUCENE-8781, we changed the FST encoding but not bump the version number we
write in its header. The change was backwards-compatible (new readers can still
read old FSTs), but not forwards-compatible: older readers would exhibit
strange behavior if they attempted to read one of these newer format FSTs.
It would be much better if readers could catch such errors and notify in a
sensible way, and we have version checking that does that; we just need to
increase the VERSION_CURRENT constant.
Also, ~[~dsmiley] points out the CHANGES.txt entries for LUCENE-8781 should be
moved to the 8.2.0 section since that change was backported. I think we can
clean that up at the same time since it's version-related.
