+** Boundaries of 'cursor-sensor-functions' now obey stickiness.
+'cursor-sensor-mode' now uses 'get-pos-property' to decide whether a
+boundary is considered as inside or outside.
+
+This means that by default, the boundaries have changed: the end
+position of a stretch of a 'cursor-sensor-functions' text property
+used to be considered outside of the stretch whereas it is now
+considered as inside.  You can recover the previous behavior by
+controlling the stickiness, for example with a call like:
+
+    (add-text-properties BEG END
+                         '(cursor-sensor-functions (MY-FUNCTION)
+                           rear-nonsticky (cursor-sensor-functions)))

 ** 'makunbound' on a variable alias undoes the alias.
 Previously, it had the effect of applying the 'makunbound' on the
 target of the alias (which can fail on some builtin variables).
