+
+* hibtypes.el (hib-link-to-file-line): Fix that a filename both in the current
+    dir and in the 'load-path' variable is expanded into a 'load-path' dir
+    first rather than the current directory, which should be preferred.
+
+* hpath.el (hpath:find): Fix (let ((buf))) when (string-empty-p path) to
+    return the current buffer when 'hpath:display-buffer' is called.  Fixes
+    bug where that function returned a window instead.
+
+* hywiki.el (hywiki-get-referent-hasht): Remove rebuild of referent-hasht
+    when empty.  This was causing a problem in the
+    'hywiki-tests--save-referent-org-id'.
+

 * hypb.el (hypb:grep-has-pcre-p, hypb:ripgrep-has-pcre-p): Add.
