Releases
StarlingX is released periodically; one release in 2018 and three releases/year starting in 2019. A release consists of a branch in the source code repositories that enables repeatable builds over time.

Release Definition
A StarlingX milestone/release is a tagged branch in the source code repositories that:
- is considered stable and can be used for repeatable builds
- will have no additional features added
- will backport bug fixes for critical issues only
- will be maintained in the canonical repositories for a specified minimum period
- The list of repos included is maintained in stx-manifest/default.xml (or similar) for any given release. (Note: this file included non-StarlingX-managed repos, only repos from the "starlingx" and "stx-staging" remotes are included.)
- The actual release is a tag on the corresponding branch, i.e. r/2018.10 release branch will be initially tagged as 2018.10.0
