Has Toad Edge Free more limitations than Toad for MySQL?

As far as I understand Toad Edge is the successor of Toad for MySQL.

Has Toad Edge Free more limitations than old Toad for MySQL?

If yes: which?

Can I access old v5 MySQL databases with Toad Edge as well or only newer v8 MySQL databases?

Can I access new v8 MySQL databases with Toad for MySQL as well or only newer v5 MySQL databases?
