I am pleased to announce the latest maintenance release of Corosync 3.1.6 available immediately from GitHub release section at https://github.com/corosync/corosync/releases or our website at http://build.clusterlabs.org/corosync/releases/.

This release contains MAJOR bugfix of totem protocol which caused loss or corruption of messages delivered during recovery phase. It is also important to pair this release with Kronosnet v1.23 (announcement https://lists.clusterlabs.org/pipermail/users/2021-November/029810.html) and Libqb 2.0.4 (announcement https://lists.clusterlabs.org/pipermail/users/2021-November/029811.html).

All our development team would like to thank the Proxmox VE maintainer, Fabian Gruenbichler, for the extremely detailed bug reports, reproducers and collecting all the data from the affected Proxmox VE users, and his dedication over the past month to debug, test and work with us.

Another important feature is addition of cancel_hold_on_retransmit option, which allows corosync to work in environments, where some packets are delayed more than other (caused by various Antivirus / IPS / IDS software).

Complete changelog for 3.1.6:

Christine Caulfield (1):
      cpghum: Allow to continue if corosync is restarted

Jan Friesse (4):
      totem: Add cancel_hold_on_retransmit config option
      logsys: Unlock config mutex on error
      totemsrp: Switch totempg buffers at the right time
      build: Add explicit dependency for used libraries

miharahiro (1):
      man: Fix consensus timeout

This upgrade is required.

Thanks/congratulations to all people that contributed to achieve this great milestone.
