 # Monaco Editor Changelog
 
+## [0.24.0] (12.05.2021)
+
+* added a setting `domReadOnly` which controls if the `<textarea>` used for editor input should have the DOM `readonly` attribute
+* added a setting `useShadowDOM` which can be set to `false` to prevent the editor from using shadow DOM in its implementation (e.g. for the contextmenus).
+* added a settings `autoClosingDelete` that controls how backspace works inside auto-closing pairs.
+* added `DiagnosticsOptions.onlyVisible` for TypeScript which limits the computation of diagnostics to only visible text models.
+* fixed issue where the editor would not load in Safari 13.
+
+### Breaking changes
+* `EditorAutoClosingOvertypeStrategy` has been renamed to `EditorAutoClosingEditStrategy`
