Release Schedule
New versions of the plugin are released approximately every week (more or less). New features are added, tested, and released incrementally, instead of grouping them together in a major version release. When minor bugs fixes and/or code improvements are applied, new versions are also released. This release schedule keeps the code stable and reliable, at the cost of more frequent updates.
See
release early, release often (RERO) software development philosophy on Wikipedia for more information on the benefits of smaller / more frequent releases.
Version Numbering
Version components:
{major}.{minor}.{bugfix}[-{stage}.{level}]
- {major} = Major structural code changes and/or incompatible API changes (ie. breaking changes).hanges).
- {minor} = New functionality was added or improved in a backwards-compatible manner.
- {bugfix} = Backwards-compatible bug fixes or small improvements.
- {stage}.{level} = Pre-production release: dev < a (alpha) < b (beta) < rc (release candidate).
