What is the release cycle?
|
|
==========================
|
|
|
|
There is no clear specified release cycle. The project follows the general
|
|
open source paradigm of release early and release often. Historically the
|
|
release cadence has been about two to three weeks.
|
|
|
|
The two weeks release cycle is a general rule of thumb. It will never be
|
|
precise down to an exact day. The decision to release is driven by the
|
|
code flow and changes made during that cycle. When a closed set of features
|
|
has been merged, then a new release is considered. When a lot changes are
|
|
merged, then the release cycle can be decreased down to weekly releases.
|
|
And in case not many changes have been made and no new features are merged,
|
|
it can happen that the release cycle becomes as long as one month.
|
|
|
|
In addition to the normal releases during a cycle, there could be also
|
|
so called brown-paper-bag type of releases. The releases are fixing
|
|
critical issues with the previous release. Normally they happen in case a
|
|
serious bug or regression slipped into the source and where it makes sense
|
|
to fix it right away. The goal is to keep this type of releases to a bare
|
|
minimum, but they do happen every now and then. From past releases they
|
|
are to be expected around three times per year.
|

|
What does the release number mean?
|
|
==================================
|
|
|
|
Every release contains a major and a minor version. The major version only
|
|
indicates an API version and it should not change until the D-Bus API is
|
|
backwards incompatible. The same major version can contain new version of
|
|
the API as long as it is backward compatible. This allows for extensions
|
|
of the D-Bus API within the same major version.
|
|
|
|
The minor version number is just an increasing number and has itself no
|
|
special meaning. The minor version will increase until a new backwards
|
|
incompatible API is required and a new major number is used.
|
|
|
|
There is no stable API guarantee for the internal plugin API. The release
|
|
numbers are not covering this.
