+Release notes for VPP 18.07
+===========================
+
+More than 533 commits since the 18.04 release.
+
+Features
+--------
+
+Infrastructure
+~~~~~~~~~~~~~~
+
+- DPDK 18.02.1
+
+ - Complete rework of the dpdk-input node
+ - Display rx/tx burst function name in “show hardware detail”
+ - Improve buffer alloc perfomance
+
+ - This is ~50% improvement in buffer alloc performance. For a 256
+ buffer allocation, it was ~10 clocks/buffer, now is < 5 clocks.
+
+ - Add per-numa page allocation info to ‘show memory’
+ - Vectorized bihash_{48,40,24,16}_8 key compare
+
+ - bihash_48_8 case:
+
+ - Scalar code: 6 clocks
+ - SSE4.2 code: 3 clocks
+ - AVX2 code: 2.27 clocks
+ - AVX512 code: 1.5 clocks
+
+ - Pollable Stats
+
+ - Stats are now available to a client in a shared memory segment
+ and in the form of a directory, allowing very high performance
+ polling of stats without directly querying VPP.
+
+VNET & Plugins
+~~~~~~~~~~~~~~
+
+- IGMP improvements
+
+ - Enable/Disable an interface for IGMP
+ - improve logging
+ - refactor common code
+ - no orphaned timers
+ - IGMP state changes in main thread only
+ - Large groups split over multiple state-change reports
+ - SSM range configuration API.
+ - more tests
+
+- IP: vectorized IP checksum
+- VXLAN : HW offload RX flow
+- Rework kube-proxy into LB plugin and add NATA66
+- NAT:
+
+ - Code refactor
+ - Syslog
+ - Multiple outside interfaces
+ - Endpoint dependent filtering and mapping
+
+- ACL:
+
+ - Tuple Merge algorithm cleanup and integration
+ - Processing pipeline optimizations
+ - Refactoring
+
+- Experimental AVF driver
+
+Host stack
+~~~~~~~~~~
+
+- Session: performance improvements, add support for connectionless
+ transports, datagram reception and transmission
+- TCP: congestion control improvements and overall fixes
+- UDP: datagram mode
+- TLS async support
