In a week, Delphi 7 Service Pack 1, or General Update 1, or whatever it would be called, would be released...
Well, at least, that's what I think anyway, given that Anders has already blogged about it here. The most, I think, would be that it would be released in 2 weeks.
Supposedly, it would fixed 100+ bugs, far shorter than John's trial of trying to provide his own “top 200” list of bugs that R&D should look at.
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.
