 * src/nsterm.m (ns_update_end): Call [view postAccessibilityUpdates].
 (ns_draw_phys_cursor): Store cursor rect; call UAZoomChangeFocus.
 (EmacsView dealloc): Release accessibilityElements.
-(EmacsView windowDidBecomeKey): Post FocusedUIElementChanged and
-SelectedTextChanged.
-(ns_ax_collect_windows): New function.  Walk window tree creating
-virtual elements.
+(EmacsView windowDidBecomeKey): Post accessibility focus notification.
+(ns_ax_collect_windows): New function.
 (EmacsView rebuildAccessibilityTree): New method.
 (EmacsView invalidateAccessibilityTree): New method.
 (EmacsView accessibilityChildren): New method.
 (EmacsView accessibilityFocusedUIElement): New method.
-(EmacsView postAccessibilityUpdates): New method.  Detect tree
-change, window switch, per-buffer changes; re-entrance guard.
-(EmacsView accessibilityBoundsForRange:): New method.  Cursor rect
-for Zoom with focused-element delegation.
+(EmacsView postAccessibilityUpdates): New method.
+(EmacsView accessibilityBoundsForRange:): New method.
 (EmacsView accessibilityParameterizedAttributeNames): New method.
 (EmacsView accessibilityAttributeValue:forParameter:): New method.
 * etc/NEWS: Document VoiceOver accessibility support.
+
+Tested on macOS 14 with VoiceOver and Zoom.  Full end-to-end: buffer
+navigation, cursor tracking, window switching, completions, evil-mode
+block cursor, org-mode folded headings, indirect buffers.
+
+Known limitations:
+- Bidi: accessibilityRangeForPosition assumes LTR glyph layout.
+- Mode-line icons: image/stretch glyphs not extracted.
+- Text cap: buffers exceeding NS_AX_TEXT_CAP (100K) truncated.
