We’ve decided to move to a Semantic Versioning-type policy starting with the release of Ruby 2.1.0.

In order to provide a more well defined and properly utilized versioning scheme for Ruby, we’ve decided to gradually switch to the following policy.

Policy Changes

This policy is based off a proposal by ruby-lang.org system administrator Hiroshi Shibata (@hsbt).

MAJOR: increased when incompatible change which can’t be released in MINOR
- Reserved for special events
MINOR: increased every christmas, may be API incompatible
TEENY: security or bug fix which maintains API compatibility
- May be increased more than 10 (such as 2.1.11), and will be released every 2-3 months.
PATCH: number of commits since last MINOR release (will be reset at 0 when releasing MINOR)

We will maintain the following branches:

The ruby_{MAJOR}_{MINOR} branch will be maintained across TEENY releases. We will use tags for each release.

The following traits can be marked as an incompatible change, requiring an increase in the MINOR version:

ABI will comply with the following scheme: {MAJOR}.{MINOR}.0

We will give our best effort to keep ABI compatibility within the same MINOR level releases, so TEENY will be fixed at 0.

I’d like to personally thank everyone who contributed to this discussion. Each step we take is closer to a more stable and effective Ruby.
