Release 4.0.3.
Improvement: Added "high sensitivity" scanning which catches evals with other bad functions but may give false positives. Not enabled by default.
Fix: Removed code that caused error message during scan initialization. 
Fix: IP to number conversation code had a problem with IP's with a single 0 in them. Bug was introduced in 4.0.2. 
Fix: Very fast attacks would generate a lot of email alerts due to race condition. Fixed.
