Versioning Policy The Authelia Versioning Policy which is important reading for administrators 2022-12-21T20:48:14+11:00 false
/versioning-policy
/versioning

The Authelia team aims to abide by the Semantic Versioning 2.0.0 policy. This means that we use the format major.minor.patch for our version numbers, where a change to major denotes a breaking change which will likely require user interaction to upgrade, minor which denotes a new feature, and patch denotes a fix.

It is therefore recommended users do not automatically upgrade the minor version without reading the patch notes, and it's critically important users do not upgrade the major version without reading the patch notes. You should pin your version to 4.37 for example to prevent automatic upgrades from negatively affecting you.

Exceptions

There are exceptions to this versioning policy.

Advanced Customizations

Some advanced customizations are not guaranteed by the versioning policy. These features require the administrator to ensure they keep up to date with the changes relevant to their version. While the customizations exist as a feature we cannot allow these customizations to hinder the development process.

Notable Advanced Customizations:

  • Templates:
    • Email
    • Content Security Policy header
  • Localization Assets

Breaking Changes

All features which are marked as:

  • beta
  • experimental

Notable examples:

  • OpenID Connect 1.0
  • File Filters

The reasoning is as we develop these features there may be mistakes and we may need to make a change that should be considered breaking. As these features graduate from their status to generally available they will move into our standard versioning policy from this exception.
