HAProxy 1.7.11 was released on 2018/04/30. It added 38 new commits after version 1.7.10.

It fixes a major issue when HAProxy is compiled with some GCC versions (<= 3.x and >= 5.x). Because of a typo in a if statement in the function bo_getline_nc(), HAProxy crashes when it tries to read from a closed socket. This issue may happen with Lua codes, when you try to read lines from a cosocket.

It also fixes an issue about stream-interfaces. Some activities on channel are lost when the stream is woken up leading to intermittent 504 errors with the improbable termination state 'sR--'. Another issue fixes how client aborts are handled during redispatch.

Some other medium issues were addressed: A memory leak in str2ip2, possible segfaults on startup when a slowstart is used, the wrapping case in the function bo_putblk and the "tcp-checks connect".

Finally, among the minor fixes and doc updates, many are about the Lua part.
