12 times 12 new features in Delphi 12

RAD Studio 12 includes some great improvements for C++Builder and the launch webinar and other online content highlights it. However, it is also a fantastic release for Delphi developers. I compiled 12 lists with 12 improvements each for Delphi 12. So this is not a list of 12 improvements for Delphi 12. It’s a list of 12×12=144 improvements, plus half a dozen for native Windows bringing the total to a whopping 150 – excluding all the existing improvements for C++Builder, as here I want to underline the Delphi side (but most of the features below are in fact for both languages).
