Hi, HAProxy 2.5.3 was released on 2022/02/18. It added 17 new commits after version 2.5.2.
This version was released shortly after the 2.5.2 because some pending patches were missing. This version fixes the pending issues that were identified in 2.5.1. Some bugs in the httpclient were found by Baptiste and Willy, one in the lua implementation that was preventing to use the same httpclient context correctly for several requests and the other one was causing a crash with the CLI implementation when the destination buffer had not enough space. In 2.5 we spent time migrating the master-worker mode to a new model that automatically switch to the wait mode after loading the configuration, helping to free the memory of the master. This new behavior revealed some issues in the wait mode that existed for a long time, but were only present upon a loading failure. We fixed some FD leaks related to this, that could have resulted in FD exhaustion after a lot of reloads and failures. Willy fixed some alignement problems that were found when using gcc-11 + RHEL8, resulting in instant crashes on startup. Lukas fixed a problem an issue with multiline ESMTP response in the mailer code. Rémi fixed some SSL issues reported by coverity. As usual, people using the 2.5 branch are encouraged to migrate to this version.
