Sorry for the long delay between mails, I've been side-tracked by various
I'm a bit confused by the branches "0.14" and "master", since my
expectation of "master" being for new features and bugfixes, while
is a stable branch that only gets bugfixes appears to be incorrect.
I am also uncertain which branch would be "recommended" as a branch to
for all the new features as they appear - "master" appears to lack certain
new features (using latest pygobject, for example), while "0.14" will
eventually be replaced with a "0.15" branch.
Master is what you should track for new features. It does look like master
is missing the new GObject patch. I probably forgot to submit the patch to
master. I will add this patch to my latest pull request (#58) Are there
any other features/fixes you expect on master that are missing?
Can you explain to me the philosophy behind these branches?
Master is the development branch and is considered unstable. Topic
branches, like 0.14 are created when the version is considered
"beta"-quality ie, features are completed but there may be some bugs.
Within the topic branches, take into account the project version number
(ambd -v). The version numbering scheme is roughly this:
0.xx.8yy - Alpha quality. Features still in development. ie 0.15.801
0.xx.9yy - Beta quality. Feature generally complete. Only bug fixes
allowed with possibly some exceptions for features. Example: 0.14.902
0.xx.0 - Final release. ie 0.13.0
0.xx.z - Bug fix release. Major bugs or security flaws may be back-ported
to released versions -often by request. ie 0.13.2
Hope that helps!
