+1.1.1
+=====
+
+This release includes the following changes:
+
+- P4-UPF:
+
+  - Fix an issue that was causing UE traffic to be dropped after restarting PFCP-Agent
+  - Allow configuration of slice rate limits via PFCP-Agent REST APIs
+  - Clean up app filter IDs when they are no longer used
+
+- ONOS:
+
+  - Support canonical representation of byte-strings for outgoing P4Runtime messages
+  - Support for in-order operations in the FlowRuleService
+
+Known Limitations
+-----------------
+- Support for slice rate limits in P4-UPF comes with the following limitations
+  that will be removed in SD-Fabric 1.2:
+
+  - We only support setting the same rate for downlink and uplink. When different
+    rates are provided using PFCP-Agent REST APIs, we pick the highest between
+    downlink and uplink.
+  - When using topologies with paired-leaves, if UE traffic is forwarded through
+    the pair link, the slice rate limit will be enforced on the aggregate of
+    uplink and downlink traffic. This can happen when the base station and/or
+    the edge server/upstream router are not dual-homed. If all endpoints are
+    dual-homed, then UE traffic if expected to use the pair link only in case of
+    failures.
