+
+Note that deprecations are an early outlook at changes
+that will appear in an eventual GTK 5 release, which is
+still far away. We are introducing deprecations in 4.10
+as a way to give users time to adapt, and to provide
+feedback on our plans.
+
+* GtkTreeView, GtkIconView, GtkComboBox and
+  auxiliary classes have been deprecated
+
+* GtkEntryCompletion has been deprecated
+
+* GtkStyleContext has been deprecated
+
+* gtk_render_ and gtk_snapshot_render_ APIs
+  have been deprecated
+
+* GtkAppChooser widgets have been deprecated
+
+* GtkMessageDialog has been deprecated and
+  replaced by a new async dialog API
+
+* GtkDialog has been deprecated
+
+* GtkColorChooser, GtkFontChooser, GtkFileChooser
+  interfaces and their implementations have been
+  deprecated. A new family of async dialog APIs
+  has been introduced to replace them
+
+* GtkColorDialog, GtkFontDialog, GtkFileDialog
+  and GtkAlertDialog are new dialog classes with
+  a consistent and well-bindable API
+
+* GtkMountOperation:
+ - Fix the dialog to look reasonable
+ - Make it work under non-X11
+
+* GtkStringSorter:
+ - Support different collation methods
+
+* Accessibility:
+ - Introduce GtkAccessibleRange and implement it
+
+* Debugging:
+ - Unify formatting for debug output
+ - Make make debug options available in
+   non-debug builds

+
+* Translation updates:
+ Abkhazian
+ Basque
+ Bulgarian
+ Croatian
+ Friulian

+ Hungarian
+ Russian
+ Turkish
+
+
+Overview of Changes in 4.8.1, 16-09-2022
+========================================
+
+* Input:
+ - Fix problems with input method interactions that caused
+   dead keys not to work
+ - Accept single-key compose sequences (these are used with
+   some keyboard layouts)
+
+* GtkColumnView:
+ - Flip column order in right-to-left context
+
+* GtkGridView:
+ - Fix problems with rubberbanding
+
+* GtkFileChooser:
+ - Fix positioning of popovers in the places view
+ - Make ~ and . keyboard shortcuts work again
+
+* gsk:
+ - Make glyph upload more similar to icons
+
+* Make file transfer via portals work, this fixes file
+  copy/paste and dnd in flatpaks
+
+* Translation updates:
+ Catalan
+ Chinese (China)
+ Chinese (Taiwan)
+ Latvian
