Re: Lucene 10.5.1 bugfix release

Is it possible to also include

* GITHUB#16400: Restore HNSW graph reuse during merges under per-field
vectors formats,
  including the default codec. Since 10.4.0 the merger tested the
per-field wrapper instead
  of the unwrapped reader, so every merge rebuilt the graph from
scratch. (Jeho Jeong)

this was a pretty bad regression I think, although indexing
performance only.  It is lacking a CHANGES entry on main, sorry
(because the bug did not occur on main)!  I can address that
separately

I think this warrants a bugfix release, and I’m happy to act as release manager (unless anybody else would like to volunteer :).
