# Versioning

When we release a new API version, by default, all requests to our backend will be served with the newest API specs. We tagged which version is the main version on our documentation page.

Now we still developing the backward-compatible way to make sure that your code will work fine when Uiza updates the API version. Because of the situation, when we make changes to the API, we release a new dated version, but to avoid breaking your code, we will inform you one month before the change by email.

Read our [Release notes](https://docs.uiza.io/api-upgrades/release-notes) to learn more about the new features we serve our customers, the bug fixes and how we improve our performance. Also, read the [API changelog](https://docs.uiza.io/api-upgrades/api-changelog) to stay up to date on the API changes.
