# Update center Release notes When releasing any update of our software, which is normally twice a month, we publish here all release notes. During each release, we gradually enable new features, starting with a randomly chosen small sample of our customers. After a few days, all new features are available to all our customers on the production server (under [**leon.aero**](https://leon.aero/)).
