All,

We are pleased to announce the general availability of kronosnet v1.32

kronosnet (or knet for short) is the new underlying network protocol for 
Linux HA components (corosync), that features the ability to use 
multiple links between nodes, active/active and active/passive link 
failover policies, automatic link recovery, FIPS compliant encryption 
(nss and/or openssl), automatic PMTUd and in general better performance 
compared to the old network protocol.

Highlights in this release:

* IMPORTANT: sctp support is now officially deprecated. It is disabled
   by default and it will be removed in knet 2.x.
* Fix potential thread race condition in libnozzle close.
* Fix wrong pointer in libknet RX thread, only triggered by old
   gcc (< 11).
* Libnozzle: different fixes for BSD to deal with new tap driver changes
   and don´t leak interfaces.
* New API call in libknet to allow configuring a dscp value for
   KNET_LINK_FLAG_TRAFFICHIPRIO.
* Bump soname to reflect new API call.
* Add support for OpenIndiana.
* Documentation updates.
* Fix several tests to better deal with execution timing.
* Handle some new coverity errors.
* Create and refine STYLE_GUIDE.md for project contributions.

Known issues in this release:

* None
