## 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/

@page release_notes_1606 Release notes for VPP 16.06


The FD.io Project, relentlessly focused on data IO speed and efficiency
supporting the creation of high performance, flexible, and scalable software
defined infrastructures, announces the availability of the community’s first
software release (16.06).

In the four months since launching, FD.io has brought together more than 75
developers from 11 different companies including network operators, solution
providers chip vendors, and network equipment vendors who are collaborating to
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.


## Features

In addition to the existing full suite of vswitch/vrouter features, the new
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:
  * Jumbo frame support for vhost-user.
  * Netmap interface support.
  * AF_Packet interface support.

* Expanded and improved programmability:
  * Python API bindings.
  * Enhanced JVPP Java API bindings.
  * Debugging CLI.

* Expanded Hardware and Software Support:
  * Support for ARM 32 targets including Rasberry Pi single-board computer.
  * Support for DPDK 16.04.
