Update Check not working correct

The update check says that my version is up to date although I have version 9.0.0.2 and the version available now is 9.0.0.3...

Is the update check server not updated or is the problem on my side?

How is the update check system working, what server is contacted and how?

Thanks

The update check didn't work for me either. I just noticed via the RSS feeds.

The updater often lags behind the official release notices here. Probably to limit the server hammering that would result if everything was notified at the same time.

Firefox does the same thing - releases are available on their website, often days before the auto update finds them.
