 + Customization group ~ement-room-list~.
 + Option ~ement-room-list-space-prefix~ is applied to space names in the room list (e.g. set to empty string for cleaner appearance).
 
++ A variety of enhancements for using compose buffers.  ([[https://github.com/alphapapa/ement.el/issues/140][#140]].  Thanks to [[https://github.com/phil-s][Phil Sainty]].)
+  + Option ~ement-room-compose-buffer-display-action~ declares how and where a new compose buffer window should be displayed.
+  + Option ~ement-room-compose-buffer-auto-scale~ causes dynamic scaling of the compose buffer window height so that the full message is visible at all times.
+  + Option ~ement-room-compose-buffer-auto-scale-min-height~ specifies the minimum window height when ~ement-room-compose-buffer-auto-scale~ is enabled.
+  + Option ~ement-room-compose-buffer-auto-scale-max-height~ specifies the maximum window height when ~ement-room-compose-buffer-auto-scale~ is enabled.
+  + Option ~ement-room-compose-method~ chooses between minibuffer-centric or compose-buffer-centric behaviour.
+  + Command ~ement-room-dispatch-new-message~ starts writing a new message using your chosen ~ement-room-compose-method~.  (Bound to ~RET~ in room buffers.)
+  + Command ~ement-room-dispatch-new-message-alt~ starts writing a new message using the alternative method.  (Bound to ~M-RET~ in room buffers.)
+  + Command ~ement-room-dispatch-edit-message~ edits a message using your chosen ~ement-room-compose-method~.  (Bound to ~<insert>~ in room buffers.)
+  + Command ~ement-room-dispatch-reply-to-message~ replies to a message using your chosen ~ement-room-compose-method~.  (Bound to ~S-RET~ in room buffers.)
+  + Command ~ement-room-compose-edit~ edits a message using a compose buffer.
+  + Command ~ement-room-compose-reply~ replies to a message using a compose buffer.
+  + Command ~ement-room-compose-send-direct~ sends a message directly from a compose buffer (without the minibuffer).  (Bound to ~C-x C-s~ in compose buffers.)
+  + Command ~ement-room-compose-abort~ kills the compose buffer and delete its window.  (Bound to ~C-c C-k~ in compose buffers.)
+  + Command ~ement-room-compose-abort-no-history~ does the same without adding to ~ement-room-message-history~.  (Equivalent to ~C-u C-c C-k~.)
+  + Command ~ement-room-compose-history-prev-message~ cycles backwards through ~ement-room-message-history~.  (Bound to ~M-p~ in compose buffers.)
+  + Command ~ement-room-compose-history-next-message~ cycles forwards through ~ement-room-message-history~.  (Bound to ~M-n~ in compose buffers.)
+  + Command ~ement-room-compose-history-isearch-backward~ initiates an isearch through ~ement-room-message-history~.  (Bound to ~M-r~ in compose buffers; continue searching with ~C-r~ or ~C-s~.)
+  + Command ~ement-room-compose-history-isearch-backward-regexp~ initiates a regexp isearch through ~ement-room-message-history~.  (Bound to ~C-M-r~ in compose buffers; continue searching with ~C-r~ or ~C-s~.)
+
++ Global minor mode ~ement-room-self-insert-mode~ enables "just typing" to start a message.  (Thanks to [[https://github.com/phil-s][Phil Sainty]].)
+  + Option ~ement-room-self-insert-chars~ determines which typed characters will immediately start a new message when ~ement-room-self-insert-mode~ is enabled.
+  + Option ~ement-room-mode-map-prefix-key~ defines a prefix key for accessing the full ~ement-room-mode-map~ when ~ement-room-self-insert-mode~ is enabled.  (By default this key is ~DEL~.)
+
 *Changes*
 
 + Bind ~TAB~ / ~BACKTAB~ to move between links in room and like buffers.  ([[https://github.com/alphapapa/ement.el/issues/113][#113]].  Thanks to [[https://github.com/ericsfraga][Eric S. Fraga]] for suggesting.)
++ When editing or replying to a message in a compose buffer, the related room event is highlighed persistently until the compose buffer is killed.  (Thanks to [[https://github.com/phil-s][Phil Sainty]].)
++ In compose buffers ~dabbrev~ will prioritise firstly the associated room, and secondly all other rooms, before looking to other buffers for completions.  (Thanks to [[https://github.com/phil-s][Phil Sainty]].)
++ Aborted messages are now added to ~ement-room-message-history~ rather than the kill-ring.  (Thanks to [[https://github.com/phil-s][Phil Sainty]].)
++ Prefix bindings in ~ement-room-mode-map~ now have named labels in ~which-key~ and similar.  (Thanks to [[https://github.com/phil-s][Phil Sainty]].)
+
+*Fixes*
+
++ Edits to previous edit events are correctly sent to the server as edits to the original message event.  ([[https://github.com/alphapapa/ement.el/issues/230][#230]].  Thanks to [[https://github.com/phil-s][Phil Sainty]].)
