+* Version 0.5.2 on 2022-10-07

+** Fixed bug in detecting the end of a clause with commented fullstops
+
+This version includes a fix in ~sweeprolog-end-of-top-term~, which is
+used to locate the end of the current clause.  Previously this
+function would get "confused" by in-clause comments that end with a
+fullstop (see the added test case in ~sweeprolog-test.el~ for an
+example).  Reported by Jan Wielemaker.
