The first release candidate of the long awaited 
ClamAV 0.90 is ready for general testing!
 
The 0.9x series introduces lots of improvements 
in terms of detection rate and performance, like 
support for many new packers and decryptors, RAR3 
and SIS archives, and a new phishing signatures 
format that proves to be very effective.
 
The email decoding has been improved to reduce
both the memory requirements and the time taken 
to process attachments.
We have been working hard also on the ClamAV 
Virus Database: we now have more than 73.000 
signatures and we keep on reviewing hundreds of 
samples everyday.
 
To cope with the increasing size of the database 
and with the high frequency of new CVD releases, 
freshclam now supports scripted updates: only the 
differences between two releases of the CVD are 
downloaded. This dramatically reduces traffic on 
our mirrors and will allow us to release even 
more updates in the future.
