Versioning and API Stability

============================
|
|
|
|
Versioning
|
|
==========
|
|
|
|
Scrapy uses the `odd-numbered versions for development releases`_.
|
|
|
|
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 backwards compatibility. Even Bs will be
|
|
stable branches, and odd Bs will be development.
|
|
* *C* is the bugfix release number.
|
|
|
|
For example:
|
|
|
|
* *0.14.1* is the first bugfix release of the *0.14* series (safe to use in
|
|
production)
|
|
|
|
API Stability
|
|
=============
|
|
|
|
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.
