A complete OpenWhisk system combines a number of software components including action runtimes, CLI tools, the core platform, the package catalog, event providers, and deployment packaging. The project makes periodic time-based unified releases that bundle a compatible set of OpenWhisk's individually released software components to make it easier for users to install a coherent and complete OpenWhisk system on their own machines.
The available unified releases are:
Individual downloads of the latest released version of each OpenWhisk component are available. Components are grouped by their role in the platform.

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 'nightly' 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 'nightly' 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.
