    • Possible RTTI problems in the latest release:
      • RTTI can't access information about Enum types with assigned values different than 0 RSP-35373
    • Note: many previously deprecated enumerations (mostly created during the switch to scoped enums) have been removed from RAD Studio 11 source
      • Example code now removed from FMX.Types.pas 
  TFormStyleHelper = record helper for TFormStyle
  const
    fsNormal = TFormStyle.Normal deprecated 'Use TFormStyle.Normal';
    fsPopup = TFormStyle.Popup deprecated 'Use TFormStyle.Popup';
    fsStayOnTop = TFormStyle.StayOnTop deprecated 'Use TFormStyle.StayOnTop';
  end;
  • Can no longer build executables for Windows XP without customization:
    • Update addressed in D28.ALEXANDRIA.11.0.0.1
    • Project Options->Building->Delphi Compiler->Linking->Set OS Version fields in PE Headers (and Set SubSystem Version fields in PE Headers" to 5.1 (it now defaults to 6.0)
    • If you use System.Threading, then need to change GetTickCount64 references to a new routine matching something like the code below and then use a modified system.thread.dcu in your projects (or update \lib\win32\debug and \lib\win32\release with new versions of System.Threading.dcu)
    • More info from Michal Mutl on Delphi PRAXIS forum message 
function _GetTickCount64: UInt64;
begin
if TOSVersion.Major<6 then
  Result := TThread.GetTickCount
else
  Result := TThread.GetTickCount64;
end;

  • XP Compatibility notes

    • As reported by Marco Cantu on Delphi PRAXIS, better HighDPI support was the reason for the PE header change. And the GetTickCount was un intentional.
    • Changing the PE format to target newer versions was a design decision. It's the same Visual Studio does. And it does make a difference in the results when invoking some HighDPI related Windows APIs. They fail to return the right value if the app is for XP, so if you change the PE setting (doable) you'll have some trouble on the latest systems. The introduction of an XP breaking issue with GetTickCount64 was not intentional and discussed. We don't test on XP by design, no one in the beta did, most likley. While we don't officially support XP, such a simple change is doable -- as long there is zero impact on newer systems and it costs a limited time. I doubt we'll release a patch for it, though...

  • High DPI form designer notes from David Millington

    • "the IDE loads the designer scaling to low DPI (96 DPI) in order to have zero impact on forms. You can scale the designer however you like - I recommend Automatic, which scales it to match whatever scale the IDE is at. If you work as part of a team and everyone has different screen scales, you can pick a specific scale you all want to use across the team and set that instead. See the doc page on high DPI in the VCL form designer here. Note that TForm.Scaled must be set to True, and also avoid using ParentFont due to issues scaling when inheriting fonts."
    • "Have you tried turning on scaling in the form designer? Tools > Options > User Interface > Form Designer > High DPI. Turn it to Automatic and it will match the scaling of the IDE. We left the default as low DPI (96) for the least impact - it means forms are left exactly the same when opening in v11. But I can see this is confusing and it may not have been the right decision."
    • In response to transition issues when selecting a new DPI, changes are saved to the DFM. "Yes. This is why we made designing at low-DPI the default - this means no changes. The changes in the DFM are unavoidable really; we may be able to scale it back to 96, but repeated scaling changes are a Bad Idea since all DPI scaling on Windows uses integer math, and with too many changes you can get controls or sizes moved incorrectly. It's better to design at something and scale at runtime (one change) than to design, save and rescale, and scale at runtime (two changes, or possibly multiple since it will upscale and downscale every time you open it.)"
    • "The best thing there is to keep designing at low DPI (96) in v11, so that your DFMs can remain the same. Then once you're comfortable with v11 you can switch on high DPI designing across all your team at once. For a team we recommend choosing a specific DPI (eg 192DPI or 200%) so that all DFMs are unchanged across your team, once you first update them."
    • Related note from online help: "The design DPI is saved in the form DFM and affects the pixel coordinates and sizes of controls (such as Left and Height.) This means that opening a form changes the values that will be saved to the DFM file. If your team uses multiple different scaling settings among team members, you can set the User Editable option on each computer to have a consistent common scaling for all forms among all team members."
    • FMX related help note: "The FireMonkey designer scales a form the same way an FMX form does at runtime. Coordinates remain the same, it is only a visual scaling. That means that a button placed at (20, 20) will be at (20, 20) no matter the high DPI scaling of the monitor the FMX designer is on."
    • High DPI requires Windows 10, from memory Creator’s Update or newer (perMonitorv2 support.) High DPI is not supported on Win 7 or Win 8.
