I couldn't have state that myself as I don't know what a label is :-) (but I don't need to know). Cheers, Willy

Regarding prometheus, it should probably noted some major changes regarding some metrics, such as for health check, where the value is now located in a label, instead of the value of the metric itself: see also http://git.haproxy.org/?p=haproxy.git;a=commit;h=de3c32638925c2071a5a84cbdafe2f112d2c4261 -- William

I think that's about it. If you contributed something that I missed here, sorry for this, that's already a lot to figure out. Don't feel upset, and just respond here to point it :-) URI normalization is missing in your summary :-) As usual, I've been careful when uploading the new release and I would not be surprised to see a 404 or two, so do not hesitate to report any issue.

[ANNOUNCE] haproxy-2.4.0
Hi, HAProxy 2.4.0 was released on 2021/05/14. It added 34 new commits after version 2.4-dev19. This completes 6 months of improvements and cleanups split into 1687 commits from 36 participants. I'm pleased to welcome these 7 new contributors who got their first commit merged into 2.4, hoping they'll want to continue: Florian Apolloner, Jan Wagner, Maciej Zdeb, Maximilian Mader, Phil Scherer, Thayne McCombs, Evgeny Varnavskiy And these 29 other ones who are not new as they already contributed before 2.4: Adis Nezirovic, Aleksandar Lazic, Amaury Denoyelle, Baptiste Assmann Bertrand Jacquin, Christian Ruppert, Christopher Faulet, Daniel Corbett, David Carlier, Dragan Dosen, Emeric Brun, Eric Salama, Frédéric Lécaille, Gilchrist Dadaglo, Ilya Shipitsin, Jerome Magnin, Joao Morais, Julien Pivotto, Matthieu Guegan, Miroslav Zagorac, Moemen MHEDHBI, Olivier Houchard, Remi Tricot-Le Breton, Thierry Fournier, Tim Duesterhus, William Dauchy, William Lallemand, Willy Tarreau, Yves Lafon It's really great to see more and more participation in multiple areas, turning good ideas into usable features, and with increasing quality overall. Let's continue like this, it's going into the right direction. Speaking of quality, for the first time we really managed to enforce the feature freeze, leading to most only harmless stuff getting merged past that point. It allowed us to focus much better than before on regressions and eliminate the usual last-minute bugs. This, combined with the work done by Ilya and Tim on the CI, and with the continuously growing set of regression tests, has significantly shortened the average lifetime of the bugs (many of which not leaving the developer's computer anymore). And this pays off: each and every -dev version among the 20 ones produced was deployed on haproxy.org, and no single failure was observed since, not even a crash, hang, leak, slow down or rendering issue. This makes me think that 2.4 out of the box is probably more reliable than the excellent 2.2 after 14 revisions. That's also why we release slightly before the initially expected deadline, it almost seems there's nothing left to be fixed! This proves that with some shared efforts it's possible to improve, and I hope that we'll continue on this trend so that 2.5 gets even better (yes, it's always possible). This version brings a few fixes for bugs and build issues on top of -dev19, very minor changes (addition of some ARM CPU targets in the Makefile to ease portable builds, a few extra normalizers, a few example files, and a sorting key for "show profiling"). Please see at the end of this message for the details. What's new in 2.4 compared to 2.3 ? Lots of cool stuff! The work was spread on several fronts: - performance and latency: a lot of work was done on locking reduction, bringing 2.4 a much lower latency than 2.3 had, and a higher scalability. 2.4 is NUMA-aware on Linux and will avoid binding to cross-socket cores by default. Idle server-side connections are now reusable even when SNI, proxy protocol or transparent proxy are used, saving costly round trips. Lua now supports lock-free multi-threading. Idle frontend connections will now be closed as soon as possible during reloads. - reliability: "strict-limits" is on by default, experimental features are protected against accidental use from a copy-paste, a diagnostic mode was added to report suspicious or uncommon constructs that could be mistakes, new live debugging tools were added for better in-field debugging. Backend idle connections will be closed before quitting so that they don't consume source ports in TIME_WAIT. - management and integration: maps and ACLs now support atomic updates, server-side SSL certificates can also be updated without reloading, servers can be added/removed without reloading (still experimental), more server settings can be edited at run time, global variables can be listed/edited at run time, "defaults" section can now be named, reused an inherited, line numbers and file names can be included in any command, file paths can now be relative to the config file, some new ".if/.elif/.else/.endif" config directives permit a smoother transition between versions using a same config file (particularly useful for automated rollbacks), - interoperability / protocol support: WebSocket over HTTP/2 (RFC8441) is now supported on both sides, regardless of the version on the other side. The cache now supports the "Vary" header with a few commonly used headers, including "Accept-encoding" which gets normalized for optimal cache hit ratio. The Prometheus exporter got a significant liftup, requires less tricks on the Prometheus side, and supports listing only certain metrics for faster retrieval. Optional native support for Opentracing was also integrated (via USE_OT=1). The DNS resolvers now support talking to
