function _git_deploy_update_refresh in Git Deploy 6.2

Same name and namespace in other branches

1. 6 git_deploy.module \_git_deploy_update_refresh()

Updates available release data given a list of projects.

We need this because loading projects within the function that fetches available releases would start an endless loop.

Parameters

array[] $projects: List of available projects.

Return value

array[] List of available releases, keyed by project name.
