You can come back to this page and switch the version of the docs you're reading at any time.
The most recent stable version (✓) is recommended for use in production.
Here you can find the latest unreleased documentation and code. You can use it to see what changes are coming and provide better feedback to MUI contributors.
Stability ensures that reusable components and libraries, tutorials, tools, and learned practices don't become obsolete unexpectedly. Stability is essential for the ecosystem around MUI to thrive.
This document contains the practices that are followed to provide you with a leading-edge UI library, balanced with stability, ensuring that future changes are always introduced in a predictable way.
MUI follows Semantic Versioning 2.0.0.
MUI version numbers have three parts:
The version number is incremented based on the level of change included in the release.
- Major releases contain significant new features, some but minimal developer assistance is expected during the update. When updating to a new major release, you may need to run update scripts, refactor code, run additional tests, and learn new APIs.
- Minor releases contain important new features. Minor releases are fully backward-compatible; no developer assistance is expected during update, but you can optionally modify your apps and libraries to begin using new APIs, features, and capabilities that were added in the release.
- Patch releases are low risk, contain bug fixes and small new features. No developer assistance is expected during update.
A regular schedule of releases helps you plan and coordinate your updates with the continuing evolution of MUI.
In general, you can expect the following release cycle:
- A major release every 12 months.
- 1-3 minor releases for each major release.
- A patch release every week (anytime for urgent bugfix).

We may decide to add or remove new items at any time, depending on our capability to deliver while meeting our quality standards.

Sometimes "breaking changes", such as the removal of support for select APIs and features, are necessary.
To make these transitions as easy as possible:
- The number of breaking changes is minimized, and migration tools provided when possible.
- The deprecation policy described below is followed, so that you have time to update your apps to the latest APIs and best practices.
- Deprecated features are announced in the changelog, and when possible, with warnings at runtime.
- When a deprecation is announced, recommended update path is provided.
- Existing use of a stable API during the deprecation period is supported, so your code will keep working during that period.
- Peer dependency updates (React) that require changes to your apps are only made in a major release.
