function hook_update_projects_alter

Alter the list of projects before fetching data and comparing versions.

Most modules will never need to implement this hook. It is for advanced interaction with the Update Manager module. The primary use-case for this hook is to add projects to the list; for example, to provide update status data on disabled modules and themes. A contributed module might want to hide projects from the list; for example, if there is a site-specific module that doesn't have any official releases, that module could remove itself from this list to avoid "No available releases found" warnings on the available updates report. In rare cases, a module might want to alter the data associated with a project already in the list.

Parameters

$projects: Reference to an array of the projects installed on the system. This includes all the metadata documented in the comments below for each project (either module or theme) that is currently enabled. The array is initially populated inside update_get_projects() with the help of _update_process_info_list(), so look there for examples of how to populate the array with real values.
