There are 3 numbers in a Scrapy version: A.B.C
- A is the major version. This will rarely change and will signify verylarge changes.
- B is the release number. This will include many changes including featuresand things that possibly break backward compatibility, although we strive tokeep theses cases at a minimum.
- C is the bugfix release number.
Backward-incompatibilities are explicitly mentioned in the release notes,and may require special attention before upgrading.
Development releases do not follow 3-numbers version and are generallyreleased as
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 inproduction)
API stability was one of the major goals for the 1.0 release.
Methods or functions that start with a single dash (
_) are private andshould never be relied as stable.
Also, keep in mind that stable doesn’t mean complete: stable APIs could grownew methods or functionality but the existing methods should keep working thesame way.
