Hi, HAProxy 2.1.1 was released on 2019/12/11. It added 43 new commits after version 2.1.0.
Overall I must say I'm particularly happy about the positive effect of the long stabilization period prior to the final release. It's been slightly more than two weeks since 2.1.0 and we didn't have a single regression yet, all bugs fixed were already present in earlier releases. As a result there is nothing dramatic, mostly some annoyances, so it's the right moment to flush the pipe and provide a cleaner version to all those who had not yet started to upgrade. Only one bug was tagged MAJOR, it's about the DNS. It's been there for a while, is unlikely to strike but when it strikes it requires a restart of the process and there is no workaround, which is why it's tagged as such. For the rest, thanks to a lot of quite detailed reports, we could address a long tail of bugs causing threads or processes to spin like crazy. Some of them were caused by a race condition in the listener code when using threads, some by the DNS, others by health checks. Another issue can occasionally cause server timeouts to be logged when using splicing. Overall nothing alarming. I suggest every user to upgrade to avoid falling into such traps, though there's no really no need to hurry.
