Versioning and API Stability
There are 3 numbers in a Scrapy version: A.B.C
- A is the major version. This will rarely change and will signify very large changes.
- B is the release number. This will include many changes including features and things that possibly break backward compatibility, although we strive to keep theses cases at a minimum.
- C is the bugfix release number.
Backward-incompatibilities are explicitly mentioned in the :ref:`release notes <news>`, and may require special attention before upgrading.
Development releases do not follow 3-numbers version and are generally
dev suffixed versions, e.g.
With Scrapy 0.* series, Scrapy used odd-numbered versions for development releases. This is not the case anymore from Scrapy 1.0 onwards.
Starting with Scrapy 1.0, all releases should be considered production-ready.
- 1.1.1 is the first bugfix release of the 1.1 series (safe to use in production)
API stability was one of the major goals for the 1.0 release.
Methods or functions that start with a single dash (
_) are private and
should never be relied as stable.
Also, keep in mind that stable doesn't mean complete: stable APIs could grow new methods or functionality but the existing methods should keep working the same way.
