Tom Preston-Werner has introduced a new feature to enhance Gem support, allowing users to initiate a Gem build directly from the interface. This improvement addresses issues where Gem builds fail due to temporary problems with the build system, suggesting that retrying the build often resolves these issues. The feature enables users to start a new build job for the latest code on their master branch, with the caveat that if a Gem of the same version already exists, the action will result in no operation.
