Hi, HAProxy 3.1.15 was released on 2026/02/19. It added 21 new commits after version 3.1.14.
This announce is quite smiliar to the 3.2.13 announce. Thanks to Mike Walker that found two issues on QUIC, both fixed. First, a possible crash issue was identified when an HTTP tunnel is established with QUIC on client side. It was fixed by reverting a commit a bit too strict. Then, it was clear that the CONNECT never worked. So it was disabled for now, waiting for time to fix it properly. Then, HTTP multiplexers were fixed to disable the 0-copy data forwarding if the stream is already closed (for h2/h3) or if the message is already finished (h1). This way, errors can be properly handled on the usual sending path. It is a theoretical issue that should not happen, except if there are internal issues. A 3.1.14 regression on applet management, preventing some applets to be properly shutdown, was fixed. Depending on the applets, the effect of this bug could vary. For the DNS applets, it could lead to a connections leak, stalled in CLOSE_WAIT state. For the peer applets, the maxconn can be reached, preventing the peers synchronisation. David Carlier fixed several minor issues on Device Atlas addon. The remaining is the usual bunch of doc improvements, small internal fixes and cleanups here and there. Everyone running QUIC on client side should consider to upgrade to this version. Thanks everyone for your help.
