-Overview of Changes in 4.13.9, xx-xx-xxxx
+Overview of Changes in 4.13.6, xx-xx-xxxx
 =========================================

-Note: The new renderers and dmabuf support are using graphics drivers
-in different ways than the old gl renderer, and trigger new driver bugs,
-(see for example https://gitlab.gnome.org/GNOME/gtk/-/issues/6418 and
-https://gitlab.gnome.org/GNOME/gtk/-/issues/6388). Therefore, it is
-recommended to use the latest mesa release (24.0) with the new renderers.
-
-
-Overview of Changes in 4.13.8, 20-02-2024
-=========================================
-
-* Accessibility:
- - Add a GtkAccessibleText interface for allowing 3rd party
-   text widgets (notably vte) to be accessible
- - Avoid duplicate accessible descriptions
- - Fix GetAccessibleAtPoint
-
-* GSK:
- - Avoid offscreens for disjoint containers
- - Don't use the gpu renderers with llvmpipe
- - Fix various rendering issues found by tests
- - Allow unnormalized node bounds again
- - Fix a broken case of rounded-rect intersection
- - Fix handling of external textures in gpu renderers
- - Make gpu renderers work with WGL on Windows
-
-* build:
- - Allow building without dmabuf support on (old) Linux
-
-* X11:
- - Fix monitor enter/leave signals
-
-* Translation updates:
- Basque
- Brazilian Portuguese
- Catalan
- Czech
- Galician
- Georgian
- Hebrew
- Lithuanian
- Persian
- Russian
- Turkish
- Ukrainian
-
-
-Overview of Changes in 4.13.7, 11-02-2024
-=========================================
-
-* GtkFileChooser:
- - Speed up opening
-
-* GtkCalendar:
- - Add some missing setters and getters
-
-* Accessibility:
- - Add socket support for webkit accessibility
- - Implement AT-SPI text for GtkText
- - Implement AT-SPI component generically
- - Add an announce API
-
-* GSK:
- - Make the ngl renderer work on macOS
- - Fix a crash in the vulkan renderer
- - Make nodeparser allow aliases for fonts again
- - Implement cache eviction for glyph and texture caches
- - Fix ngl shaders to work on GL < 4.0
- - Require GL 3.3 for the ngl renderer
- - Fix problems with scaled shadows
- - Fix problems with holes for underlaid subsurfaces
- - Improve handling of scales and glyph cache efficiency
-
-* Media:
- - Support dmabufs in the gstreamer backend. This allows
-   zero-copy video playback on Wayland when paired with
-   hardware video decoding
- - Drop the experimental ffmpeg backend. It hasn't been
-   building for a year
-
-* Wayland:
- - Commit empty frames if and double-buffered state is pending
- - Fix monitor size information when using mutter without
-   the scale-monitor-framebuffer setting
- - Clear the current tablet on tab leave, fixing a crash
-
-* macOS:
- - Propagate unhandled input events back to the OS
-
-* Tools:
- - Make the crash handling in gtk4-node-editor more robust
-
-* Translation updates
- Galician
- Georgian
- Occitan
- Turkish
-
-
-Overview of Changes in 4.13.6, 25-01-2024
-=========================================
-
-This release changes the ngl renderer to be the default renderer.
-
-The intent of this change is to get wider testing and verify that
-the new renderers are production-ready. If significant problems
-show up, we will revert this change for 4.14.
-
-You can still override the renderer choice using the GSK_RENDERER
-environment variable.
-
-Since ngl can handle fractional scaling much better than the old gl
-renderer, we allow fractional scaling by default with gl now. If you
-are using the old gl renderer (e.g. because your system is limited to
-GLES2), you can disable fractional scaling by setting the GDK_DEBUG
-environment variable to include the gl-no-fractional key.
-
-* GtkColumnView:
- - Fix infinite loops in dispose
- - Fix problems with weak ref cycles in GtkExpression
-
-* GtkListView:
- - Fix some corner cases with sections during insertions and deletions
- - Don't double-recycle widgets
-
-* GtkStack:
- - Add automatic cleanup for GtkStackPage
-
-* GDK:
- - Use standard cursor names for drag cursors
- - Enable fractional scaling with gl by default
-
-* GSK:
- - Many fixes and improvements to the unified renderers:
-   - Fix text rendering with the uber shader
-   - Fix rounding issues with fractional scales
-   - Fix some memory leaks
-   - Many text rendering fixes
-   - Implement subpixel positioning for glyphs
-   - Support custom fonts in node files
-   - Add tests for font rendering
-   - Fix drawing of repeat nodes
-   - Implement subpixels positioning
-   - Evict stale textures, glyphs and atlases from the cache
- - Some fixes and improvements to the GL renderer:
-   - Fix problems with GLES on Nvidia
-   - Avoid a crash in the mask demo
-   - Respect opacity of the first child node in containers
- - Some fixes and improvements to the fallback renderer:
-   - Fix drawing of repeat nodes
- - Make ngl the default renderer
-
-* Wayland:
- - Fix problems with tablet cursors
- - Fix problems without seats
-
-* Accessibility:
- - Respect a separate "show-status-shapes setting
- - Fix change notification for accessible names on some widgets
-
-* Inspector:
- - Show the git commit in devel builds
-
-* Tools:
- - Make gtk4-node-editor autosave its contents
- - Add a benchmark command to gtk4-rendernode-tool
-
-* Translation updates:
- French
- Galician
- Georgian
- Occitan
- Persian
- Russian
- Vietnamese
