I have just inherited a MultiSite install with about 100 plugins, many of them out of date, and I have noticed that they dont seem to be getting update notifications. And yes, I have checked for updates from the Network Admin dashboard
For instance, the jetpack plug is currently at 3.5.3 and the version currently located on wordpress.org is at 3.7.2 which includes a bug fix we need BUT there is no notification of an update in the dashboard.
Is there a filter or setting which prevents these update checks? Is there a way to update it manually (without uploading the folders via FTP) or to force WordPress to check for the update? Or is this a feature of MultiSite?
