> In LUCENE-8781, we changed the FST encoding but did 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.
