 <!-- Maintainers and contributors: Insert change notes for the next release above -->
 
+### Breaking changes
+
+#### `Session.new_window()` + `Window.split_window()`: No longer attaches by default
+
+- 0.28 +: Now _defaults_ to `attach=False`.
+- 0.27.1 and before: _defaults_ to `attach=True`.
+
+Pass `attach=True` for the old behavior.
+
+#### `Pane.resize_pane()` renamed to `Pane.resize()`: (#523)
+
+This convention will be more consistent with `Window.resize()`.
+
+#### `Pane.resize_pane()`: Params changed (#523)
+
+- No longer accepts `-U`, `-D`, `-L`, `-R` directly, instead accepts
+  `ResizeAdjustmentDirection`.
+
+### New features
+
+#### `Pane.resize()`: Improved param coverage (#523)
+
+- Learned to accept adjustments via `adjustment_direction` w/
+  `ResizeAdjustmentDirection` + `adjustment`.
+
+- Learned to accept manual `height` and / or `width` (columns/rows or percentage)
+
+- Zoom (and unzoom)
+
+#### `Window.resize_window()`: New Method (#523)
+
+If `Pane.resize_pane()` (now `Pane.resize()`) didn't work before, try resizing the window.
+
+### Bug fixes
+
+#### `Window.refresh()` and `Pane.refresh()`: Refresh more underlying state (#523)
+
+#### `Obj._refresh`: Allow passing args (#523)
+
+e.g. `-a` (all) to `list-panes` and `list-windows`
+
+#### `Server.panes`: Fix listing of panes (#523)
+
+Would list only panes in attached session, rather than all in a server.
+
 ### Improvement
 
 - Pane, Window: Improve parsing of option values that return numbers
   (#520)
+- `Obj._refresh`: Allow passing `list_extra_args` to ensure `list-windows` and
+  `list-panes` can return more than the target (#523)
