End of Life Announcement: ClamAV 0.94.x
October 5th, 2009 Posted by – webmaster
All ClamAV releases older than 0.95 are affected by a bug in freshclam which prevents incremental updates from working with signatures longer than 980 bytes.
You can find more details on this issue on our bugzilla (see bug #1395)

This bug affects our ability to distribute complex signatures (e.g. logical signatures) with incremental updates.

So far we haven’t released any signatures which exceed this limit.
Before we do we want as many users as possible to upgrade to the latest version of ClamAV.

Starting from 15 April 2010 our CVD will contain a special signature which disables all clamd installations older than 0.95 – that is to say older than 1 year.

This move is needed to push more people to upgrade to 0.95 .
We would like to keep on supporting all old versions of our engine, but unfortunately this is no longer possible without causing a disservice to people running a recent release of ClamAV.
The traffic generated by a full CVD download, as opposed to an incremental update, cannot be sustained by our mirrors.

We plan to start releasing signatures which exceed the 980 bytes limit on May 2010.

We recommend that you always run the latest version of ClamAV to get optimal protection, reliability and performance.

Thanks for your cooperation!
