New version scheme to support branchy workflow Prepare to switch to the workflow described by "git help workflows". In this workflow, the "master" branch is always used to integrate topics ready for release. Brand new work merges into a "next" branch instead. We need a new versioning scheme to work this way because the version on "master" must always increase. We no longer use an even/odd minor number to distinguish releases from development versions. Since we still support cvs checkout of our source tree we cannot depend on "git describe" to compute a version number based on the history graph. We can use the CCYYMMDD nightly date stamp to get a monotonically increasing version component. The new version format is "major.minor.patch.(tweak|date)". Releases use a tweak level in the half-open range [0,20000000), which is smaller than any current or future date. For tweak=0 we do not show the tweak component, leaving the format "major.minor.patch" for most releases. Development versions use date=CCYYMMDD for the tweak level. The major.minor.patch part of development versions on "master" always matches the most recent release. For example, a first-parent traversal of "master" might see v2.8.1 2.8.1.20100422 v2.8.2 | | | ----o----o----o----o----o----o----o----o---- Since the date appears in the tweak component, the next release can increment the patch level (or any more significant component) to be greater than any version leading to it. Topic branches not ready for release are published only on "next" so we know that all versions on master lead between two releases.
