Following the beta testing period and some blog post pre-announcing some of the key features (see also my blog), yesterday Embarcadero officially released RAD Studio 10.4 Sydney, which includes Delphi 10.4.
There are many new features in the product. For Delphi developers the key are:
There is way more in the product, this is just my personal take of the top 3 areas we worked on. Extensive bug fixing is another key element of 10.4, with one of the highest number of public reported bug fixed in a release. And the return of a very nice classic Delphi Greek helmet logo!

more about RAD 10.4 against 10.3.3
I installed Delphi Sydney 10.4 on my desktop computer running Windows 10 Pro 64-bitsand all the components I am using on the projects I am developing on Delphi Rio 10.3.3.I did not uninstall Delphi Rio 10.3.3 before the installation of Delphi 10.4 Sydney.Then I opened the project (I am developing on Delphi Rio 10.3.3) on Delphi 10.4 Sydney.Note: I use on the project the Signature Konopka VCL Controls 6.2.3, Ehlib VCL and other VCL controls from Delphi.1) Delphi 10.4 Sydney changed the colors of the forms and the buttons of the project to clBtnFace andthe color of the font of the captions of the labels and the caption of the buttons from clNavy to clBlack.2) I tried to change the colors of these components but it was impossible.You can change the value of the Color property of the component on the Object Inspectorbut the color of the component does not change.3) On Delphi 10.4 Sydney when I open the LiveBindings panel and click on the three dots of any component rectangleDelphi 10.4 Sidney closes without any warning.4) I closed Delphi 10.4 Sydney.5) When I opened Delphi Rio 10.3.3, a message was shown informing that theSignature Konopka VCL Controls and the EhLib VCL controls could not be loaded.6) I installed these components again on Delphi Rio 10.3.3. Then I closed Delphi Rio 10.3.3.When I opened Delphi Rio 10.3.3 again the same message was shown informing that theSignature Konopka VCl Controls and the EhLib VCL components could not be loaded.7) I removed Delphi 10.4 Sydney from my desktop computer.8) I installed the Signature Konopka VCL Controls and the EhLib VCL Components on Delphi Rio 10.3.3and these components was loaded on Delphi Rio 10.3.3 without problem.I have never seen such kind of errors on the prior Delphi versions.
I use also the Konopka Controls. And I have 10.3.3 and 10.4 installed parallel. Except that the controls are not available for 10.4 now it works without any problem. But I hope the Signature Konopka VCL Controls are soon available for 10.4. It's the last thing I need to move my main project to 10.4....
"1) Delphi 10.4 Sydney changed the colors of the forms"You can see your color on design mode by active GlassFrame property of the form.
