Mike Sokolov reassigned LUCENE-8844:

>                 Key: LUCENE-8844
>                 URL:
>             Project: Lucene - Core
>          Issue Type: Bug

>            Priority: Major
> 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
> 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.
