@page release_notes_1807 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

## API changes

- Python API: To avoid conflicts between VPP API messages names and
  the Python API binding function names, VPP API methods are put in a
  separate proxy object.
  https://gerrit.fd.io/r/#/c/5570/
  The api methods are now referenced as:
    vpp_handle = VPP(jsonfiles)
    vpp_handle.connect(...)
    vpp = vpp_handle.api
    vpp.show_version()
    vpp_handle.disconnect()

  For backwards compatibility VPP API methods are left in the main
  name space (VPP), but will be removed from 17.07.

  - Python API: Change from cPython to CFFI.

- create_loopback message to be replaced with create_loopback_instance
  create_loopback will be removed from 17.07.
  https://gerrit.fd.io/r/#/c/5572/

enhance and innovate around the Vector Packet Processing (VPP) technology. The
FD.io community has quickly formed to grow the number of projects from the
initial VPP project to an additional 6 projects addressing a diverse set of
requirements and usability across a variety of deployment environments.

The 16.06 release brings unprecedented performance: 480Gbps/200mpps with 8
million routes and 2k whitelist entries on standard high volume x86 servers.

16.06 release adds:

* Enhanced Switching and Routing:
  * IPv6 Segment Routing multicast support.
  * LISP xTR support.
  * VXLAN over IPv6 underlay.
  * Per interface whitelists.
  * Shared adjacencies in FIB.

* New and improved interface support:
