+light0.1beta0.17
+--------
+	 * Major bugfix: race in logfile switchover could sometimes
+	   lead to the wrong logfile (extremely rare to hit, but
+	   potentially harmful).
+	 * Disallow primary switching when some secondaries are
+	   syncing.
+	 * Fix logfile fetch from multiple peers.
+	 * Fix computation of transitive closure (affected
+	   log-purge-all, split brain detection, and many others).
+	 * Fix incorrect emergency mode detection.
+	 * Primaries no longer fetch logfiles (unnecessarily, only
+	   makes a difference at concurrent split brain operations).
+	 * Detached resources no longer fetch logfiles (unexpectedly).
+	 * Myriads of smaller fixes.
