Release process
===============
Maintain the release notes in this file with a list of new features and API changes in each major release.
Major releases:
1. Create branch release-X from master.
2. Remove any unfinished features.
3. Test and fix any problems found.
4. Tag X.0.
Minor (bugfix) releases:
1. Backport bugfixes from the master branch or fix bugs specific to old releases into the currently maintained release-X branch(es).
2. When significant bugs have been fixed, tag X.Y+1.
3. To help dealing with regressions, no new features or refactorings should be implemented in release-X branches. Those happen in the master branch, and then a new release-X+1 branch is created.
Release notes
=============
