When I check for updates with the new version of Glider I get:
Checking for updates failed.
Check your network connection, verify that your proxy settings are configured correctly, or try again later.
The Glider Update Center link points to:

Hello ingemar,
That would be correct. There are no updates available yet for this version of Glider

OK.
It was the message “update failed” that got me.
I would have expected “No updates available” in that case 
Another (off-topic) question:
Can I use my old license file with the new version?
Of course. The update is free.
