+*** Add an argument to ~org-export-to-file~ and ~org-export-to-buffer~
+
+~org-export-to-file~ and ~org-export-to-file~ can run in a different
+process when provided a non-nil =ASYNC= optional argument, without
+relying on ~org-export-async-start~ macro.
+
+Since =ASYNC= is the first of optional arguments, you have to shift
+the other optional arguments accordingly.
+
+*** Export back-ends are now structures
+
+Export back-ends are now structures, and stored as such in the
+communication channel during an export process.  In other words, from
+now on, ~(plist-get info :back-end)~ will return a structure instead
+of a symbol.
+
+Arguments in hooks and in filters are still symbols, though.

+*** Anonymous export back-ends
+
+~org-export-create-backend~ can create anonymous export back-ends,

+
+It allows for quick translation of Org syntax without the overhead of
