====================================
|
|
|
|
|
|
|
|
|
|
Support of the Rails framework is divided into four groups: New features, bug
|
|
|
|
|
fixes, security issues, and severe security issues. They are handled as
|
2014-05-29 22:35:12 -04:00
|
|
|
follows, all versions in `X.Y.Z` format.

2014-05-29 22:35:12 -04:00
|
|
|
Rails follows a shifted version of [semver](http://semver.org/):
|
|
|
|
|
|
|
|
|
|
**Patch `Z`**
|
|
|
|
|
|
|
|
|
|
Only bug fixes, no API changes, no new features.
|
2014-05-30 10:44:55 -04:00
|
|
|
Except as necessary for security fixes.
|
2014-05-29 22:35:12 -04:00
|
|
|
|
|
|
|
|
**Minor `Y`**
|
|
|
|
|
|
|
|
|
|
New features, may contain API changes (Serve as major versions of Semver).
|
2014-05-30 10:44:55 -04:00
|
|
|
Breaking changes are paired with deprecation notices in the previous minor
|
|
|
|
|
or major release.
|
2014-05-29 22:35:12 -04:00
|
|
|
|
|
|
|
|
**Major `X`**
|
|
|
|
|
|
|
|
|
|
New features, will likely contain API changes. The difference between Rails'
|
|
|
|
|
minor and major releases is the magnitude of breaking changes, and usually
|
|
|
|
|
reserved for special occasions.

New Features

|
------------
|
|
|
|
|
|
2013-10-02 18:26:58 -04:00
|
|
|
New features are only added to the master branch and will not be made available
|
2013-09-09 06:09:38 -04:00
|
|
|
in point releases.

Bug Fixes
|
2013-09-09 06:09:38 -04:00
|
|
|
---------
|
|
|
|
|
|
|
|
|
|
Only the latest release series will receive bug fixes. When enough bugs are
|
|
|
|
|
fixed and its deemed worthy to release a new gem, this is the branch it happens
|
|
|
|
|
from.
|
|
|
|
|
|
2014-09-12 14:54:08 -04:00
|
|
|
In special situations, where someone from the Core Team agrees to support more series,
|
|
|
|
|
they are included in the list of supported series.
|
|
|
|
|
|
2019-08-16 18:39:22 -04:00
|
|
|
**Currently included series:** `6.0.Z`.

Security Issues
|
|
|
|
|
---------------
|
2013-09-09 06:09:38 -04:00
|
|
|
|
|
|
|
|
The current release series and the next most recent one will receive patches
|
|
|
|
|
and new versions in case of a security issue.
|
|
|
|
|
|
|
|
|
|
These releases are created by taking the last released version, applying the
|
|
|
|
|
security patches, and releasing. Those patches are then applied to the end of
|
|
|
|
|
the x-y-stable branch. For example, a theoretical 1.2.3 security release would
|
|
|
|
|
be built from 1.2.2, and then added to the end of 1-2-stable. This means that
|
|
|
|
|
security releases are easy to upgrade to if you're running the latest version
|
|
|
|
|
of Rails.
|
|
|
|
|
|
2019-08-16 18:46:01 -04:00
|
|
|
**Currently included series:** `6.0.Z`, `5.2.Z`.

Severe Security Issues
|
|

|

2018-04-10 18:42:27 -04:00
|
|
|
For severe security issues all releases in the current major series, and also the
|
2019-08-28 05:46:30 -04:00
|
|
|
last release in the previous major series will receive patches and new versions. The
|
2013-09-09 06:09:38 -04:00
|
|
|
classification of the security issue is judged by the core team.
|
|
|
|
|
|
2019-08-16 18:39:22 -04:00
|
|
|
**Currently included series:** `6.0.Z`, `5.2.Z`.

Unsupported Release Series
|
|
|
|
|
--------------------------
|
|
|
|
|
|
|
|
|
|
When a release series is no longer supported, it's your own responsibility to
|
2013-10-02 18:26:58 -04:00
|
|
|
deal with bugs and security issues. We may provide backports of the fixes and
|
2013-09-09 06:09:38 -04:00
|
|
|
publish them to git, however there will be no new versions released. If you are
|
|
|
|
|
not comfortable maintaining your own versions, you should upgrade to a
|
|
|
|
|
supported version.
