The new Artifact Page in Bitrise allows testers to find and access all test builds of their apps in one place, streamlining the process of locating older test builds and reducing unnecessary frustration. The page features a list of installable artifacts with details and CI build information, enabling users to download or install artifacts directly, view more details, and access a private install page for secure distribution. This improvement is particularly useful when external testers need to be shared access to test builds without authorization, while also providing an additional layer of security through the private install page.
