Might break compat for some thirdparty modules that include e.g. core/dvector.h or core/io/resource_import.h, would be worth mentioning in the changelog @Calinou.

@akien-mga Added to my working copy of the changelog 🙂 I guess I'll send another PR before the 3.1 release.

[akien-mga]

Only modules/ left to review, and this should be good to merge.

In platform/, there's also OSIPhone that would be good to rename to OS_IPhone for consistency with other platforms, but I didn't want to break #22784 so it will have to wait.

[akien-mga]

Done modules/ too.

• in platform/windows

Might be worth considering "Win32" because UWP is also Windows (10). Though this may be jumping the gun a bit, since I don't think UWP will become the default for at least another decade.

• EditorExportAndroid and EditorExportUWP renamed to
  EditorExportPlatformAndroid and EditorExportPlatformUWP

Why not ExportPlatformWhatever? grep -RIni ExportPlatform | grep -v EditorExportPlatform gives no results, I don't see why the Editor part is necessary. (where else are you exporting from?)

• scene/resources/color_ramp.h -> gradient.h

Wow, I've never seen gradients called "color ramp" before :P

Might be worth considering "Win32" because UWP is also Windows (10).

Don't see much use for renaming it this way, and it would be a massive change (and compat breakage for build scripts).

Why not ExportPlatformWhatever?

Most editor classes start with Editor.
