to Ubuntu 20.04.2 LTS. Upgrade included also baseline Docker
containers used for spawning topology.
+ - **TRex upgrade v2.86 to v2.88**: Included move to DPDK 21.02 and
+ changed the way egress low latency queues are used in FVL NICs.
+ This broke latency measurements for majority of FVL NICs in
+ CSIT. Latency values look better after upgrading FVL FW on TRex
+ servers, but still somewhat higher than before the TRex upgrade.
+ Tracked by `CSIT-1790 <https://jira.fd.io/browse/CSIT-1790>`_.
+
- **CSIT test environment** version has been updated to ver. 7, see
:ref:`test_environment_versioning`.
