Versioning

Apache OpenWhisk uses semantic versioning. Version numbers use the form major.minor.incremental-build and are incremented as follows:

  • major version: for incompatible API changes.
  • minor version: for new functionality added in a backward-compatible manner.
  • incremental version: for forward-compatible bug fixes.
  • build: optional postfix to distinguish intermediate builds.

Developer Builds

Most of the Apache OpenWhisk project component repositories are configured within GitHub to automatically generate interim builds (not official release builds) for each merged Pull Request (PR) and/or on a nightly basis. These builds, by default, are tagged 'latest' and appear under their respective GitHub component's release tab and are intended for developer evaluation and testing only.

In some special cases, Committers on the project may choose to use GitHub to tag certain builds as they become closer to being Release Candidate (RC) builds. However, any build tagged within GitHub with either 'latest' or any other tag do NOT have official Apache project release status. All official Apache OpenWhisk release builds undergo a rigorous process to be approved and are linked above.

To be clear, GitHub "releases" are not official Apache OpenWhisk project releases.
