HAProxy 1.6.11 was released on 2016/12/25. It added 24 new commits
after version 1.6.10.

The most important changes are fixes for out-of-memory conditions, possibly
causing some applets to remain stuck when waiting for a buffer to be available
(possibly impacting peers, Lua or CLI). Some inter-task signals could also be
lost in such a condition, possibly causing some delays with cosockets in Lua.
The server-side SNI appeared to be unreliable because once a connection was
established to the server, the same SSL session was reused as long as possible,
thus with the same SNI. Not only would it interact badly with helth checks, but
also with multiple SNIs to the server. The rest is the usual bag of small
harmless issues.

If 1.6.10 works fine for you and you're not running in memory-constrained
environments, there's no urge to upgrade. But it doesn't hurt anyway :-)
