+2007-09-18  Exal de Jesus Garcia Carrillo  <exal@gmx.de>
+
+        * erc.texi (Special-Features): Fix small typo.
+
+2007-09-16  Michael Olson  <mwolson@gnu.org>
+
+        * erc-track.el (erc-track-switch-direction): Mention
+        erc-track-faces-priority-list.  Thanks to Leo for the suggestion.
+
+2007-09-11  Exal de Jesus Garcia Carrillo  <exal@gnu.org>
+
+        * erc-sound.el: Fix typo in setting up instructions.
+
+2007-09-10  Michael Olson  <mwolson@gnu.org>
+
+        * Makefile (elpa): Copy dir template rather than echoing a few
+        lines.  The reason for this is that the ELPA package for ERC was
+        getting a corrupt dir entry.
+
+        * dir-template: Template for the ELPA dir file.
+
 2007-09-08  Michael Olson  <mwolson@gnu.org>
 
+        * erc-log.el (erc-log-filter-function): New option that specifies
+        the function to call for filtering text before writing it to a log
+        file.  Thanks to David O'Toole for the suggestion.
+        (erc-save-buffer-in-logs): Use erc-log-filter-function.  Make sure
+        we carry along the value of coding-system-for-write, because this
+        could potentially be shadowed by the temporary buffer.
+
         * erc.el (erc-version-string): Update to 5.3, development version.
