Deprecation Policy

Because zuul-jobs is intended for wide use by any Zuul, we try to take care when making backwards incompatible changes.

If we need to do so, we will send a notice to the zuul-announce mailing list describing the change and indicating when it will be merged. We will usually wait at least two weeks between sending the announcement and merging the change.

If the change affects your jobs, and you are unable to adjust to it within the timeframe, please let us know with a message to the zuul-discuss mailing list -- we may be able to adjust the timeframe. Otherwise, you may wish to temporarily switch to a local fork of zuul-jobs (or stop updating it if you already have).

New Zuul Features

When a new feature is available in Zuul, the jobs in zuul-jobs may not be able to immediately take advantage of it. We need to allow time for folks to upgrade their Zuul installations so they will be compatible with the change. In these cases, we will wait four weeks after the first Zuul release with the required feature before merging a change to zuul-jobs which uses it.

Deprecated Zuul Features

Before deprecating a feature in Zuul which is used by zuul-jobs, the usage of the feature must be removed from zuul-jobs according to the deprecation policy described above.
