+### Bug Fix(s)
+* <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Issue is fixed where on running a test with a large number of `replay_updates` multiple times would cause a PCPU out of memory crash, resulting in <i>"context deadline"</i> error on `set_config` or `set_control_state.protocol.start`.
+
+
+#### Known Issues
+* <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: If `keng-layer23-hw-server` version is upgraded/downgraded, the ports which will be used from this container must be rebooted once before running the tests.
+* <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: `StartProtocols`/`set_control_state.protocol.all.start` can get stuck till the time all DHPCv4/v6 clients receive the leased IPv4/v6 addresses from the DHCPv4/v6 server/relay agent. This may result in getting `"context deadline exceeded"` error in the test program.
+* <b><i>UHD400</i></b>: Non default virtual wiring configuration can result in ARP failures and traffic loss due to dropped packets on the rx path.
+* <b><i>UHD400</i></b>: Packets will not be transmitted if `flows[i].rate.pps` is less than 50.
+* <b><i>UHD400</i></b>: `values` for fields in flow packet headers can be created with maximum length of 1000 values. If larger set of values are required for a field which are random, please use `random` instead of `values`.
+* <b><i>Ixia-C</i></b>: Flow Tx is incremented for flow with tx endpoints as LAG, even if no packets are sent on the wire when all active links of the LAG are down. 
+* <b><i>Ixia-C</i></b>: Supported value for `flows[i].metrics.latency.mode` is `cut_through`.
+* <b><i>Ixia-C</i></b>: The metric `loss` in flow metrics is currently not supported.
+* <b><i>Ixia-C</i></b>: When flow transmit is started, transmission will be restarted on any existing flows already transmitting packets.

-# Release Features(s)
-
-* <b><i>UHD400</i></b>: Support added to retrieve timestamp of the last link state change event of the test port. [More Details](https://github.com/open-traffic-generator/models/pull/398)
-  - This can be retrieved by accessing `port_metrics[i].last_change`.
-
-    Note:
-      - Test ports and DUT must be time synced to the same time source if link state change timestamps need to be co-related.
-
 
 ### Bug Fix(s)
-* <b><i>Ixia-C & UHD400</i></b>: For certain asymmetric configurations of BGPv4/v6 `replay_updates` with a large number of updates, `set_config` or `set_control_state.protocol.start` would result in the protocol-engine container to get stuck and ultimately result in `context_deadline_exceeded` error and subsequent actions to not return a response. This issue is fixed.
+* <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Issue is fixed where on running a test with a large number of `replay_updates` multiple times would cause a PCPU out of memory crash, resulting in <i>"context deadline"</i> error on `set_config` or `set_control_state.protocol.start`.
 
 
 #### Known Issues
 * <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: If `keng-layer23-hw-server` version is upgraded/downgraded, the ports which will be used from this container must be rebooted once before running the tests.
 * <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: `StartProtocols`/`set_control_state.protocol.all.start` can get stuck till the time all DHPCv4/v6 clients receive the leased IPv4/v6 addresses from the DHCPv4/v6 server/relay agent.
