+* This is mainly a maintenance release to fix compatibility issue with upcoming
+  release of dplyr.
+* Accordingly, `gghighlight_point()` and `gghighlight_line()` became defunct.
+  Considering that these functions have been deprecated for 1.5 years, I expect
+  there will be little impact on users.
