-Version 3.12.4 (rgerhards), 2008-03-??
+Version 3.12.4 (rgerhards), 2008-03-25
+- Greatly enhanced rsyslogd's file write performance by disabling
+  file syncing capability of output modules by default. This
+  feature is usually not required, not useful and an extreme performance
+  hit (both to rsyslogd as well as the system at large). Unfortunately,
+  most users enable it by default, because it was most intuitive to enable
+  it in plain old sysklogd syslog.conf format. There is now the
+  $ActionFileEnableSync config setting which must be enabled in order to
+  support syncing. By default it is off. So even if the old-format config
+  lines request syncing, it is not done unless explicitely enabled. I am
+  sure this is a very useful change and not a risk at all. I need to think
+  if I undo it under compatibility mode, but currently this does not
+  happen (I fear a lot of lazy users will run rsyslogd in compatibility
+  mode, again bringing up this performance problem...).
 - added flow control options to other input sources
+- added $HHOUR and $QHOUR system properties - can be used for half- and
+  quarter-hour logfile rotation
+- changed queue's discard severities default value to 8 (do not discard)
+  to prevent unintentional message loss
+- removed a no-longer needed callback from the output module 
+  interface. Results in reduced code complexity.
 - bugfix/doc: removed no longer supported -h option from man page

   the patch
