We are pleased to announce the general availability of kronosnet v1.13

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 performances 
compared to the old network protocol.

Highlights in this release:

* Optimize reassembly of defrag packets by avoid unnecessary memmoves.
* Improvements to the test suite to deal with the above bugs and
   potentially reduce regressions in future.
* Minor stability fixes to the test suite.
