This new release includes some major cleanup to the code base of packet.dll aimed at having more stable and easily maintainable code. It also includes a more coherent use of the tracing macros, as well as some bug fixes related to AirPcap support and the use of WinPcap in conjunction with some VPN clients.
Moreover, starting from this release, the support for Windows 95/98/ME has been dropped.
Full details can be found in the changelog.
Being a beta release, as usual we encourage people to test it and report any anomaly or strange behavior to the WinPcap mailing lists.
The final release of WinPcap 4.0 is expected to be available by the end of January 2007.
