STARS 2.2 was officially released in August 2019 and is the latest version. Periodic administrative updates may be released, but there are currently no planned substantive changes.
We have just started the technical development process for version 3.0 and we anticipate that process to be finalized no sooner than late 2023. The tentative STARS 3.0 Development Timeline provides more detailed information on the development process. A Vision for STARS 3.0 was approved by the Steering Committee in November 2019.
