Embarcadero has announced the RAD Studio 13 beta and invites customers to join it!
Codenamed Ganymede, RAD Studio 13 will be named Florence.
Only customers on the update subscription will be invited to join the beta testing, and Embarcadero has already sent invitations to customers on subscription.
In 2017, with the release of Delphi 10.2 Tokyo, Embarcadero introduced a specialized implementation of the Observer pattern into the System.Classes unit. While it has been in the wild for 9 years, it remains a "hidden" architecture for many, primarily because it serves as the invisible engine behind LiveBindings. Other than live bindings, you can also use the Observer pattern as a way to update component settings to the Windows registry, an .ini file, or persist it elsewhere.
