# API changelog

> API changes, new features, and breaking changes in the c.technology platform.

## Backwards compatibility

In accordance with [semantic versioning](https://semver.org), major version changes may introduce breaking changes, minor releases add new features in a backward-compatible manner, and patch releases include backward-compatible bug fixes and usability improvements (as such, API requests only use `vX.Y` without the patch version).
Please review the breaking changes section for any updates that may require adjustments in your integration.

Old releases are supported for **6 months** after a new major or minor version is released.
After this period, we recommend updating to the latest version to ensure continued support and access to new features.
