We are pleased to announce the general availability of kronosnet v1.25

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:

* Fix an important PMTUd issue when node joins a cluster in the presence
   of a network device that is black-holing packets
* Fix handling of PMTUd packets when firewalls are misconfigured on TX
* Fix build with gcc-12
* Update doxyxml from libqb
* Minor spec, docs, build and typos fixes

Known issues in this release:

* None
