Change to version numbering with Sophos Anti-Virus version 3.86 onwards

From the October 2004 release (version 3.86) onwards, the following versions of Sophos Anti-Virus separately report a software version number and a virus data version number. The Sophos Anti-Virus version is in the form 3.XX.Y, or 4.XX.Y and the virus data version is in the form 3.XX or 4.XX:

The XX will continue to increment each month in both cases.

The third digit, Y, on the Sophos Anti-Virus version indicates a patch or bug fix release.

For example, in October 2004 the Sophos Anti-Virus version is set to 3.86.0 for all platforms, and the virus data version is set to 3.86. If a bug fix is issued on a particular platform the Sophos Anti-Virus version becomes 3.86.1. for the first bug fix version, 3.86.2 for the second bug fix version, etc. In November 2004, when the virus data increments to 3.87, the above Sophos Anti-Virus versions are set to 3.87.0.

Note: The version numbering for Sophos Anti-Virus for Windows 95/98/Me changed in the November (3.87) release.
