Beginning with the October 2023 release, Optimizely Configured Commerce versions will be marked with a **+STS** (Short-Term Support) or **+LTS** (Long-Term Support).  Just like any other deployment, you must include the release version number in the `VersionInfo.yaml` file in the customer’s extensions repository to deploy.

STS releases maintain the same month-to-month support as usual. This means that a week before a new release, Configured Commerce no longer publishes changes to the previous release, and all hotfixes are for the current release.

LTS releases only receive new features when a new branch is released (three times a year), which contains features from the previous STS release. This means the features have already been tested in live environments. LTS branches do receive hotfixes for their four-month life, and the hotfixes end the week before a new LTS branch release.

## Swap between LTS and STS

Customers can swap between LTS and STS if they want the new features from the STS branch or want to move from a STS branch to a more stable version with the next LTS release. However, version numbers can only go up for releases. Version numbers cannot be downgraded. For example, a customer on 5.1.2309.xxxx+LTS can go to 5.1.2310.xxxx+STS, and a customer on 5.1.2310.xxxx+STS can move to 5.1.2313.xxxx+LTS during the next LTS release. Customers on 5.1.2310.xxxx+STS cannot downgrade to 5.1.2309.xxxx+LTS.
