 #. VPP PERFORMANCE TESTS
 
    - **Service density 2n-skx tests**: Added higher NF density tests with
-     802.1q (vlan) and 802.1ad (vxlan) encapsulation from Traffic Generator.
+     802.1q (vlan) and VXLAN encapsulation from Traffic Generator.
 
-   - **GBP tests**: Added GBP routing test cases with 802.1q (vlan) external
-     traffic.
+   - **GBP tests**: Added GBP (Group Based Policy) routing test cases
+     with 802.1q (vlan) external traffic.
 
-   - **AVF IPv4 scale tests**: Increased coverage of AVF IPv4 base and scale
-     test cases.
+   - **AVF IPv4 scale tests**: Increased coverage of AVF IPv4 base and
+     scale test cases (Fortville NICs only).
 
-   - **2n-skx tests**: Increased coverage of selected (COP, iACL, Policer)
-     test cases.
+   - **2n-skx tests**: Increased coverage of selected (COP, iACL,
+     Policer) test cases.
 
    - **IPsec scale tests**: Added IPsec interface mode scale tests with
-     1, 40, 400, 1000, 5000, 10000, 20000, 40000, 60000 tunnels. Removed DPDK
-     backend dependency.
-
-   - **Hoststack TCP tests**: Added Hoststack TCP performance tests
-     using WRK to the HTTP static server plugin measuring connections
-     per second and requests per second.
-
-   - **Changed methodology of dot1q 2n tests**: dot1q encapsulation is now used
-     on both links of SUT. Previously dot1q was used only on a single link with
-     the other link carrying untagged Ethernet frames. This change results in
-     slightly lower throughput in CSIT-1908 for these tests.
+     1, 40, 400, 1000, 5000, 10000, 20000, 40000, 60000 IPsec tunnels.
+     Removed DPDK backend dependency. Major IPsec test code
+     refactoring.
+
+   - **Hoststack TCP/IP tests**: Major refactor of Hoststack TCP
+     performance tests using WRK generator talking to the VPP HTTP
+     static server plugin measuring connections per second and
+     requests per second.
+
+   - **Changed methodology of dot1q tests in 2-Node testbeds**: dot1q
+     encapsulation is now used on both links of SUT. Previously dot1q
+     was used only on a single link with the other link carrying
+     untagged Ethernet frames. This change results in slightly lower
+     throughput in CSIT-1908 for all dot1q tests in all 2-Node
+     testbeds.
+
+   - **KVM VM vhost-user tests**: completed move to Kernel-VM for all
+     tests. In addition to running DPDK Testpmd as VM workload, new
+     tests created with VPP as VM workload. VPP in VM is the same
+     version as the DUT VPP (acting as vSwitch) and its configuration
+     depends on the test type. For all L2 Ethernet Switching tests
+     it's vpp-l2xc (L2 cross-connect), for all IPv4 Routing tests it's
+     vpp-ip4 (VPP IPv4 routing).
 
 #. TEST FRAMEWORK
 
-   - **CSIT PAPI Support**: Finished conversion of CSIT VAT L1 keywords to
-     PAPI L1 KWs in CSIT using VPP Python bindings. Redesign of key components
-     of PAPI Executor and PAPI history. Currently the only exception is
-     usage of VAT command for scale configuration.
+   - **CSIT PAPI Support**: Finished conversion of CSIT VAT L1 keywords
+     to PAPI L1 KWs in CSIT using VPP Python bindings (VPP PAPI).
+     Redesign of key components of PAPI Socket Executor and PAPI
+     history. Due to issues with PAPI performance, VAT is still used
+     in CSIT for all VPP scale tests. See known issues below.
 
    - **General Code Housekeeping**: Ongoing RF keywords optimizations,
      removal of redundant RF keywords and aligning of suite/test
