+- Tuning: logresolvemerge.pl is 30 times faster when merging a lot of log\r
+  files (1000) at same time (Thanks to Dan Armstrong).\r
 - Added detection of linux and bsd distributions (redhat, mandriva, ...)\r
   Thanks for idea to Sean Carlos.\r
 - Added option SkipReferrersBlackList to exlude records from SPAM referrers.\r
