Moodle plugin isn't alerting a new version is available
We were running until this morning 1.0-rc.3 (2016092100) on our Moodle 2.9 site. However, the normal notification of a newer version being available was not presented to us in Moodle's plugin management UI (see attached image).
It was only when I came to update the h5p libraries from the h5p library page, and I was presented with a message saying that 2 tools could not be updated as they were on the wrong version, that I then went to check on moodle.org to see if there was an update to the plugin (which there was, 1.0-rc 4). One I updated the plugin to 1.0-rc4 could I then successfully update the libraries.
I don't know if it was just a blip with our site, or a problem with 1.0-rc3 but it would appear that there is an issue with the plugin 'calling home' to Moodle.org's plugin directory for version checking.
