Previous FreeCAD release notes can be found in the Feature list.

General

Multiple documents can now be edited simultaneously with independent tasks and undo/redo stacks, for example, having two Sketches open at the same time (GSoC project). Pull request #21978
.FCBak backup files can now be opened directly from the File → Open dialog without renaming them to .FCStd first. Saving such a file triggers Save As… to prevent accidentally overwriting the backup. Pull request #28454

User interface

Further user interface improvements

The built-in text editor now supports line selection via clicking on the line number (and optionally also holding Shift for range selection). Pull request #27677
In the built-in text editor, the search field is now prefilled with the currently selected text. Pull request #27674
Double-clicking a face of the navigation cube will now rotate to it, but also center the view. Pull request #28608
The Recompute Object Tree View context menu option (Std_Recompute command) now has a keyboard shortcut Ctrl+Shift+R. Pull request #27880
