Hi, HAProxy 1.6.4 was released on 2016/03/14. It added 73 new commits after version 1.6.3.
First, a handful of severe bugs were fixed and some of them also affect older versions. One could cause a server's port to be overwritten upon reload when both the DNS and server-state-file are used. Another one could cause some connections to freeze and remain orphaned when an idle timeout stroke during http-reuse. It was more visible with maxconn. This bug was reported by Yves Lafon who provided lots of useful dumps and tried debugging code to help figure what was happening, so many thanks for this! Thierry fixed a major Lua bug preventing an applet from being woken up. Baptiste found that using L7 sample fetches in "tcp-request connection" rulesets would cause a nice segfault. It was even broader than that, any L5-7 fetch there can cause this, except the few that still had the double check. Finally, the variables could also crash the process if improperly used (eg: using session variables at the connection level). Last, I remember there were several people reporting the systemd-wrapper was leaving some processes behind. I found a few race conditions that I fixed. I hope it will be enough. The remaining bugs are numerous but not critical, see the changelog. While not a bug, the default mailer timeout change was backported from 1.7 to ensure more reliable operation (changed to 10 seconds), as well as the change disabling the connection retry on a server already marked down, and the content-length header that's now added in the stats response to avoid a risk of truncated responses and permit client-side keep-alive. The other changes are just here to support the respective fixes.
