# SDK Support Policy

Statsig provides official support only for SDK versions released within the past **one year**, unless otherwise specified. Some updates may require a different timeline or migration path.

## Supported versions

- Statsig provides support (bug reports, issue investigation, and compatibility assistance) for SDK versions released **within the past 12 months**.
- Statsig considers versions older than one year **unsupported**. They may continue to function, but Statsig doesn't guarantee their behavior or compatibility with backend services.
- Upgrade to the latest version to benefit from new features, performance improvements, and critical fixes.

## Versioning and releases

- All SDKs follow [Semantic Versioning (SemVer)](https://semver.org/), using the format `MAJOR.MINOR.PATCH`, **unless otherwise specified**.

  - **MAJOR**: breaking changes
  - **MINOR**: backwards-compatible new features
  - **PATCH**: backwards-compatible bug fixes
- Statsig publishes release notes in the GitHub Releases section of each SDK’s repository. These notes contain details on changes, improvements, and upgrade instructions.

## Open source and community contributions

- Statsig releases all SDKs as open source under the [ISC License](https://opensource.org/licenses/ISC), allowing developers to freely use, modify, and distribute them.
- Statsig welcomes and encourages community contributions.

## Get help
