Hi, HAProxy 2.8.18 was released on 2025/12/25. It added 1 new commits after version 2.8.17.
One fix for an H2 idle connection issue that was thought to affect all versions has a bad effect alone on 2.8, causing idle connections not to be preserved after a certain number accumulate, resulting in a high connection rate on the backend. Let's revert the fix for now to address the problem. If it turns out in the future that this fix is really needed for 2.8, then we'll backport the few other ones that come with it, but that are still a bit tricky and that we prefer to postpone for now. If you don't use H2 on the backend, no need to update.
