announcing ClamAV 0.90RC1
|
|
Dear ClamAV users,
The first Release Candidate of the long awaited ClamAV 0.90 is ready for
general testing! This version introduces lots of new interesting
features and marks a big step forward in the development of our antivirus
engine.
The most important change is the introduction of scripted updates.
Instead of transferring the whole cvd file at each update, only the
differences between the latest cvds and the previous versions will be
transferred.
In case the local copy of the latest cvd is corrupted or the scripted
update fails for some reason, freshclam will fallback to the old method.
Similarly to cvd files, scripted updates are compressed and digitally
signed and are already being distributed. They will dramatically reduce traffic
on our mirrors and will allow us to release even more updates in the
future.
Another noticeable change is the new configuration syntax: you can now
turn single options on and off, the old crude hack of
"DisableDefaultScanOptions" is no longer required.
Cosmetic changes apart, the 0.9x series introduces lots of new code, but
some parts are not compiled in by default because they are not ready for
production systems yet. You are encouraged to pass the --enable-experimental
flag to ./configure when compiling ClamAV. If you find a bug, please take
some time to report it on our bugzilla: http://bugs.clamav.net. Your help
in testing the new code is really appreciated.
The experimental code introduces many improvements in terms of detection
rate and performances.
RAR3, SIS and SFX archives support is finally available together with
new unpackers and decryptors: pespin, sue, yc, wwpack32 and others.
Additionally, ClamAV now includes better mechanisms for scanning ELF,
PDF and tar files.
As part of the Google Summer of Code program, we have introduced support
for a new phishing signatures format that has proved very effective in
detecting phishing emails. The ClamAV phishing module allows better and more
generic detection of phishing emails by searching for URLs in email messages,
and comparing the real site with the URL displayed to the user in the
message.
On the performance side, support for the MULTISCAN command has been
implemented in clamd, allowing to scan multiple files simultaneously.
Support for Sensory Networks NodalCore (http://www.clamav.net/nodalcore/)
acceleration in ClamAV is now available and will be compiled in if the
ncore libraries are detected at compile time.
NodalCore acceleration allows highly improved scan speeds on systems
equipped with NodalCore cards.
