TEST FRAMEWORK + + - **CSIT test environment** version has been updated to ver. 11, see + :ref:`test_environment_versioning`. + + - **TCP tput profiles** have to be changed, as newer TRex versions + are not deterministic enough when deciding when to send an ACK. + + - **CSIT PAPI support**: Due to issues with PAPI performance, and + deprecation of VAT, VPP CLI is used in CSIT for many VPP scale + tests.
