+- Fix Settings spacing around Screen capture, automatic layout correction and layout controls.
+- Verify update checksums through .NET SHA-256 without requiring the PowerShell Get-FileHash command. This fixes updates from processes launched with a conflicting PowerShell module environment.
 - Capture a rectangular screen region with Win+Shift+S (configurable), with dimmed selection and independent editor windows.
 - Annotate screenshots with numbered markers, arrows, straight/freehand lines, highlights, rectangles, circles, ellipses and inline text.
 - Edit color, line style, arrowheads, thickness, font and size. Link arrow endpoints to markers and attach captions.

 - Compact Lucide toolbar, contextual status bar, pencil cursor and confirmation before discarding an uncopied screenshot. Escape no longer closes the editor.
 - Preserve the separate on-demand configurator and configurable capture shortcut.

+**Upgrade from v0.3.0 or v0.4.0:** use Update in the tray menu. Both executables are supported.
+If an older updater reports missing `Get-FileHash`, restart KSwitcher normally from Explorer
+(outside a PowerShell 7 session) or install this ZIP manually once. v0.4.1 removes that dependency.
 **Upgrade from v0.2.3 or earlier:** install manually once because those updaters reject the additional configurator EXE.
 Exit KSwitcher and extract the entire ZIP into its installation folder. Keep personal `data/` and customized dictionaries.
