      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
