 # Release Features(s)
 
-* <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Support added for OSPFv2. [details](https://github.com/open-traffic-generator/models/pull/384)
+* <b><i>Ixia-C, UHD400</i></b>: Support added for DHCPv6 Client and Server in control plane.
+  - User will be the able to configure DHCPv6 Client and Server by the following code snippet.
   ```go

-    ospfRoutes.
-            Addresses().
-            Add().
-            SetAddress("10.10.10.0").
-            SetPrefix(24).
-            SetCount(100).
-            SetStep(2)
-  ```
+      // Configure a DHCPv6 Server
+      d1Dhcpv6Server := d2.DhcpServer().Ipv6Interfaces().Add().
+        SetName("p2d1Dhcpv6Server1").
 
-  - Learned LSAs can be fetched by the following
-  ```go
-    req := gosnappi.NewStatesRequest()
-    req.Ospfv2Lsas().SetRouterNames(routerNames)
-    res, err := client.GetStates(req)
+      d1Dhcpv6ServerPool := d1Dhcpv6Server.SetIpv6Name("p2d1ipv6").
+        Leases().Add().
+        SetLeaseTime(3600)
+      IaType := d1Dhcpv6ServerPool.IaType().Iata()
+      IaType.
+        SetStartAddress("2000:0:0:1::100").
+        SetStep(1).
+        SetSize(10).
+        SetPrefixLen(64) 
   ```
 
-  - OSPFv2 metrics can be fetched by the following 
+* <b><i>UHD400</i></b>: Support of Egress Flow tracking for multiple flows is added any location of supported fields upto 10 bits.
+  - Supported fields are `ethernet.src/dst`, `vlan.id`, `vlan.priority`, `ipv4.src/dst`, `ipv4.precedence`, `ipv6.src/dst`, `ipv6.traffic_class`.
   ```go
-    req := gosnappi.NewMetricsRequest()
-    reqOspf := req.Ospfv2()
-    reqOspf.SetRouterNames(routerNames)
+    eth := flow.EgressPacket().Add().Ethernet()
+    ipv4 := flow.EgressPacket().Add().Ipv4()
+    ipv4Tag := ipv4.Dst().MetricTags().Add()
+    ipv4Tag.SetName("flow_ipv4_dst")
+    ipv4Tag.SetOffset(22)
+    ipv4Tag.SetLength(10)
   ```
 
-
-* <b><i>Ixia-C, Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Support added to update `flows[i].size` and `flows[i].rate` on the fly.
+* <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Support added for ISIS Simulated Topology. [More Details](https://github.com/open-traffic-generator/models/pull/327)
+  - Configuration for ISIS attributes for newly introduced simulated routers are identical to configuration for currently supported directly connected emulated routers.
+  -  `devices[i].ethernets[j].connection.simulated_link` is introduced to create a simulated ethernet connection to build a Simulated Topology.
   ```go
-    
-    flow = get_config.Flows().Items()[0]
-    flow.Rate().SetPps(120)
-    flow.Size().SetFixed(512)
+    simulatedRouterEthernet := simulatedRouter.Ethernets().Add().
+                SetName("simRtrEth").
+                SetMac("00:00:11:02:02:02")
+    simulatedRouterEthernet.Connection().SimulatedLink().SetRemoteSimulatedLink("connRtrSimEth")
 
-    flowUpdateCfg: = gosnappi.NewConfigUpdate().Flows()
-    flowUpdateCfg.Flows().Append(flow)
-    flowUpdateCfg.SetPropertyNames ([]gosnappi.FlowsUpdatePropertyNamesEnum{
-      gosnappi.FlowsUpdatePropertyNames.SIZE, gosnappi.FlowsUpdatePropertyNames.RATE
-    })
-
-    configUpdate = gosnappi.NewConfigUpdate()
-    configUpdate.SetFlows(flowUpdateCfg)
-    res, err := client.Api().UpdateConfig(configUpdate)
+    connectedRouterSimulatedEthernet := connectedRouter.Ethernets().Add().
+                SetName("connRtrSimEth").
+                SetMac("00:00:01:01:01:01")
+    connectedRouterSimulatedEthernet.Connection().SimulatedLink().SetRemoteSimulatedLink("simRtrEth")
   ```
+  Note: `get_metrics/states` APIs are only applicable for the connected emulated routers and not for the simulated routers.
+
+* <b><i>Ixia-C, UHD400, Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Support added for fetching `lldp_neighbors[i].custom_tlvs[j].information` as hex bytes using `get_states` API. [More details](https://github.com/open-traffic-generator/models/pull/392)
 
 ### Bug Fix(s)
-* <b><i>Ixia-C</i></b>: Issue where flows containing `ipv4/v6` header without `src/dst` specified was returning error on `set_config` <i>"Error flow [ flow-name ] has AUTO IPv4 src address and Tx device [ flow-end-point ] with no dhcpv4 interface"</i> is fixed.
+* <b><i>Ixia Chassis & Appliances(Novus, AresOne)</i></b>: Issue is fixed where for certain scenarios such as retrieving large control capture buffer or fetching `get_metrics/states` for large amount of data results in errors similar to <i>"grpc: received message larger than max (7934807 vs. 4194304)"</i>. 
+  - For such scenarios note that the grpc receive buffer on the client should also be locally increased if necessary from default value of 4 MB.
+
+* <b><i>Ixia-C</i></b>: Issue is fixed for LLDP where, when multiple custom tlvs are configured to be sent, sometimes the bytes in the `information` field in the outgoing LLDP PDUs were corrupted.
