Release Process

The OpenFlow Spec and Reference Implementations are available from two different sources:

• OpenFlow Git Repository contains the source code for trunk, beta and releases.
• Download Page has OpenFlow releases

The life cycle for a new OpenFlow release is:

• Planning. New features and spec changes are recorded on a wiki page, then discussed on the OpenFlow-discuss and OpenFlow-spec mailing lists. Change requests come from both vendors and researchers; this is meant to be an open process.
• Implementation. Once a feature has been agreed upon, the implementation starts with a single commit to a new feature branch. This commit includes the set of changes to the OpenFlow spec, as well as any changes to openflow.h; it defines a contract (which may be changed as the implementation progresses) of what must be changed to OpenFlow to implement the new feature. Each new feature goes into its own branch on the public OpenFlow git repository, prepended by the developer's handle. The feature branch should include regression tests, changes to the Wireshark dissector, and updates to man pages.
• Review. The burden is on the feature developer to find at least one developer to do a public code review before any code may get pushed to the testing branch. This may require multiple passes and should result in code improvements.
• Testing. As a first check, the release candidate is run against our regression suite, which tests individual OpenFlow message types (black_box tests), as well as checks that the sample controller plus the OpenFlow switch act as an Ethernet switch (learning_switch tests). The Wireshark Dissector is hand-verified by checking its output during a run of the black_box tests. In addition, we do feature testing with the release candidate by adding it to whatever apps we're currently running on top of OpenFlow and checking that nothing breaks.
• Release. The release is tagged in Git, and posted on the Download page.
• Maintenance. Bug fixes releases come after new-feature releases.
