+## 0.20.0 - 2026-05-25
+
+[0.20.0-commits]
+
+This is the first release using wlroots-0.20 and therefore has an increased risk
+of teething issues. Many thanks to @Consolatis for leading the effort to port
+across [#2956].
+
+In terms of new features, the most noteworthy ones include: (i) the frequently
+requested show-desktop action; (ii) initial toplevel capture support to
+screenshot specific windows; (iii) menu accelerators/shortcuts; and (iv) HDR10
+support when running with the Vulkan renderer option.
+
+The eagle-eyed amongst you will have noticed the sudden jump from labwc `0.9.7`
+to `0.20.0`. The reason for this is to align the minor number to that of the
+wlroots version against which the compositor is linked.
+
+The 0.9.x series has turned into a maintenance branch named v0.9 with bug fixes
+only, for anyone preferring to build with wlroots-0.19.
+
+Note to maintainers:
+
+- libinput >=1.26 is required in support of tablet tool pressure range
+  configuration.
+- wlroots >=0.20.1 is required to avoid some bugs that we do not want labwc to
+  ship with. For details, see:
+  https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/5325
+
+### Added
+
+- Partially support toplevel-capture. Note that the following are not yet
+  implemented: (i) XWayland child windows; (ii) XWayland unmanaged windows
+  (e.g. popups); (iii) xdg child window positioning; (iv) xdg subsurfaces;
+  and (v) xdg popup positioning. [#2968] @Consolatis
+- Add command line option -t|--title to set the labwc window title when running
+  nested [#3577] @mdsib
+- Add support for HDR10 output @kode54 @Consolatis [#3424]
+- Include wlroots version in --version string @Consolatis [#3567] [#3581]
+- Implement menu accelerators (one-letter mnemonics to quickly select/exec
+  items from the current menu) @ch3rn1ka [#3505]
+- Add Next/PreviousWindowImmediate actions @elviosak @johanmalm [#3547]
+- Add labnag options `--details-border-color` and `--details-margin`
+  @st0rm-shad0w [#3527]
+- Add config option `<focus><raiseOnFocusDelay>` to defer raise-on-focus by a
+  small amount when `raiseOnFocus` is enabled  @joske [#3513]
+- Install `labwc-session.target` systemd user unit when the systemd dependency
+  is available  @joske [#3534]
+- Add `onbutton` to config option `<libinput><device><scrollMethod>`. Also add
+  associated option `<libinput><device><scrollButton>`. @diniamo [#3540]
+- Add `overrideInhibition` option to `<keybind>` [#3507] @drougas
+- Add action `ToggleShowDesktop` to hide/unhide windows, and default keybind
+  `Super-d` to trigger this action [#3500] [#3595] @johanmalm
+- Add `<privilegedInterfaces>` config option so that privileged protocols can be
+  restricted [#3493] @xi
+- Add action `DebugToggleKeyStateIndicator` to show a key-state on-screen
+  display (OSD) for debugging. [#3499] @johanmalm @tokyo4j
+- Add support for `color-management-v1` and `color-representation-manager-v1`
+  protocols [#3469] @ManuLinares
+- Add configuration option `<tabletTool minPressure="0.0" maxPressure="1.0" />`
+  to enable tablet tool pressure range libinput settings [#2916] @jp7677

+- Position chromium popup correctly when a window is maximized on a multi-
+  output setup @elviosak [#3547]
+- Run session activation environment update synchronously to avoid a race

+- Allow interactive resize on fully maximized windows so that a resize
+  initiated by modifier plus right-mouse-button-drag is not ignored [#3525]
+  @bjorn
+- Gracefully handle missing XWayland packages, so that a labwc compositor which
+  has been built with XWayland support (which is optional) can be run even if
+  XWayland is not installed. [#3401] @quite
+- Rework how XWayland window initial geometry is set to ensure that the natural
+  geometry does not exceed the usable output area when handling initial
+  maximize/fullscreen requests. [#3439] @jlindgren90.
+- For XWayland windows, sync always-on-top state back to X.Org Server. This
+  makes `wmctrl -b toggle,above` work. [#3446] @jlindgren90
+- Fix missing title and icon with XWayland client override-redirect toggle.
+  There are no known issues with clients, so this is purely for preventative
+  purposes. [#3450] @jlindgren90
+- Update titlebar title when set to empty and fix an associated issue causing
