2018.11.22 Embarcadero has released a shining new version of Delphi, with new language, RTL, VCL, FireMonkey, mobile, database and RAD Server features, plus a large number of quality improvements.
Delphi 10.3 has been released as part of RAD Studio 10.3. The new release has a very large number of features, in many different areas, which you can read in the product main page and documentation (see links below).
There are a few things in Delphi 10.3 I'm personally proud of and would like to underline:
the new inline variable declaration, a small change that breaks with the original Pascal language opening up a lot of new possibilities for improving your every day code; its effects include block variable lifetime and visibility, type inference, and a few more
the image collection and the new virtual image list for VCL Hi-DPI applications; nothing in Microsoft own Windows UI comes close in terms of API integration, compatibility with different versions of Windows, easy transition of existing code. Same for the new Per Monitor v2 support deep in the VCL. VCL and Delphi continue to lead as the best Windows UI library
the large expansion of FireMonkey on the Android platforms with native controls, z-Order, better editing support, new permissions architecture and more
the "2.0" version of RAD Server, with better URL and content type mapping, server side components, a more flexible architecture, and the ability to avoid repeated boilerplate code
the overall focus on RTL performance
a very very nice UI and UX for the IDE itself, makes it hard to go back to 10.2
the C++ 17 work is also great, even if not strictly Delphi
