The ROS buildfarm keeps track of which packages (and repositories) are released and generates status_pages accordingly. It allows, for example, to compare the repositories released in every active ROS distribution.
To ease the release process for maintainers the buildfarm now generates a status page to show all repositories from the previous ROS distribution and see which ones can be released and / or are blocking the release of other repositories.
Several labels have been introduced to make it easier for maintainers to know which repositories can('t) be released and their impact on downstream repositories. For example the label="UNBLOCKED_BLOCKING" shows the list of all repositories that can be released and preventing other repositories from being released.
Additionally this page can be used to check the status of a single repository using the id tag. For example the repository "robot_model" can be monitored using id="robot_model"
