Release v2.10.16

Changelog

Refer to the 2.10 Upgrade Guide for backwards compatibility notes with 2.9.x.

Warning

A possible regression may result in a server panic at startup when tav.idx files were incorrectly truncated down to zero bytes. You can work around this problem by deleting tav.idx files that are zero bytes in length before starting the server. Zero-byte files could exist as a result of a previous server crash before a successful file sync to disk occurred.
