 ### Changed
 
+- When a Wayland-native window is snapped to a screen edges or user-defined
+  region, labwc will notify the application that it is "tiled", allowing the
+  application to better adapt its rendering to constrained layouts. Windows
+  with client-side decorations may respond to these notices by squaring off
+  corners and, in some cases, disabling resize abilities. This can be disabled
+  with:
+
+```xml
+<snapping>
+  <notifyClient>never</notifyClient>
+</snapping>
+```
+
+  or limited to only edge-snapped or only region-snapped windows. See the
+  labwc-config(5) manual page for more information.
+
+- When a window is dragged from a snapped position (either a screen edge or a
+  user-defined region), the snapped state is now discarded as soon as the
+  dragging begins. This means that dragging from a snapped position to a
+  maximized state (with the `topMaximize` option enabled) and then
+  un-maxmimizing the window will restore the window to its size and position
+  *before* it was snapped. In previous releases, un-maximizing would restore
+  the window to its snapped state. To preserve the snapped state of a window
+  when maximized, use the Maximize window button or the `ToggleMaximize`
+  action.

-- Support showing the full `app_id` in window-switcher (configured using the
-  keyword `identifier`).
-- For anyone using `identifier` in window-switcher field configuration, change
-  it to `trimmed_identifier` to keep looks the same. Issue #1309
+- Support showing the full `app_id` in the window switcher. Users with a custom
+  `windowSwitcher` configuration should use the `trimmed_identifier` field
+  label to preserve existing behavior; the `identifier` field now refers to the
+  full `app_id`. Consult the labwc-config(5) manual page for more details.
