================

Preliminaries
-------------

- Make sure that ``RELEASE_NOTES.rst`` and ``ANNOUNCE.rst`` are up to
  date with the latest news in the release.

- Check that *VERSION* symbols in blosc/blosc.h contains the correct info.

- Commit the changes::

    $ git commit -a -m"Getting ready for X.Y.Z release"


Testing
-------

Create a new build/ directory, change into it and issue::

  $ cmake ..
  $ cmake --build .
  $ ctest

To actually test Blosc the hard way, look at the end of:

http://blosc.org/synthetic-benchmarks.html

where instructions on how to intensively test (and benchmark) Blosc
are given.


Tagging
-------

- Create a tag ``X.Y.Z`` from ``master``.  Use the next message::

    $ git tag -a vX.Y.Z -m "Tagging version X.Y.Z"

- Push the previous commits and tag to the github repo::

    $ git push
    $ git push --tags


Announcing
----------

- Send an announcement to the blosc, pytables-dev, bcolz and
  comp.compression lists.  Use the ``ANNOUNCE.rst`` file as skeleton
  (possibly as the definitive version).


Post-release actions
--------------------

- Edit *VERSION* symbols in blosc/blosc.h in master to increment the
  version to the next minor one (i.e. X.Y.Z --> X.Y.(Z+1).dev).

- Create new headers for adding new features in ``RELEASE_NOTES.rst``
  and add this place-holder instead:

  #XXX version-specific blurb XXX#

- Commit the changes::

    $ git commit -a -m"Post X.Y.Z release actions done"
    $ git push


That's all folks!
