3 x 12 IDE, Installer and Delphi Language Enhancements in Delphi 12

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).

• The first blog post had 3 x 12 VCL Enhancements in Delphi 12, as you can read at https://blogs.embarcadero.com/3-x-12-vcl-enhancements-in-delphi-12/.
• The second blog post focused on FireMonkey and the Android platform support, as you can see at https://blogs.embarcadero.com/3-x-12-firemonkey-and-android-enhancements-in-delphi-12/.
• The third installment had three lists focused on three related areas, Delphi Runtime Library (RTL), database access, and Internet access, as you can see at https://blogs.embarcadero.com/3-x-12-rtl-data-and-internet-enhancements-in-delphi-12/
