Sanic uses calendar versioning, aka "calver". To be more specific, the pattern follows:


Generally, versions are referred to in their YY.MM form. The MICRO number indicates an incremental patch version, starting at 0.

Reporting a Vulnerability#

If you discover a security vulnerability, we ask that you do not create an issue on GitHub. Instead, please send a message to the core-devs on the community forums. Once logged in, you can send a message to the core-devs by clicking the message button.

Alternatively, you can send a private message to Adam Hopkins on Discord. Find him on the Sanic discord server.

This will help to not publicize the issue until the team can address it and resolve it.

Release Schedule#

There are four (4) scheduled releases per year: March, June, September, and December. Therefore, there are four (4) released versions per year: YY.3, YY.6, YY.9, and YY.12.

This release schedule provides:

  • a predictable release cadence,
  • relatively short development windows allowing features to be regularly released,
  • controlled deprecations, and
  • consistent stability with a yearly LTS.

We also use the yearly release cycle in conjunction with our governance model, covered by the S.C.O.P.E.

Long term support v Interim releases#

Sanic releases a long term support release (aka "LTS") once a year in December. The LTS releases receive bug fixes and security updates for 24 months. Interim releases throughout the year occur every three months, and are supported until the subsequent release.

Before a feature is deprecated, or breaking changes are introduced into the API, it shall be publicized and shall appear with deprecation warnings through two release cycles. No deprecations shall be made in an LTS release.

Breaking changes or feature removal may happen outside of these guidelines when absolutely warranted. These circumstances should be rare. For example, it might happen when no alternative is available to curtail a major security issue.
