WinPcap 4.0 beta1 is available as of today in the download section of 
the WinPcap website, http://www.winpcap.org/install/.

This release addresses some bugs in WinPcap 4.0 alpha1 reported by our
users (problems sending OID requests to the WinPcap driver, and empty 
packets while capturing from dialup/VPN adapters). 
  
This build also includes support for wireless capture through the CACE
Technologies AirPcap adapter, and a major rewriting of the transmit 
capabilities exposed by pcap_send() and pcap_inject(). Moreover, a 
deeper testing of the library on Vista Beta2 has been performed.
 
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 complete change log is attached at the end of this message.

Changelog
=========

- Added support for AirPcap adapters.

- Rewritten the transmit code in the driver (NPF_Write()), in order to
  improve its solidity:
  + the IRP is not marked as pending 
  + we use a different algorithm to stop transmitting when the packets
    are all pending 
  + added a new NdisEvent for the management of the transmit 
    operations. 
  + added a counter used upon transmission with NPF_Write() to keep 
    track of the number of pending packets.

- Added a global version header file that is used for all the modules 
  of WinPcap.
  
- Updated the license in the installer and on the web to account for 
  the third party source files used by WinPcap and libpcap.
  
- Updated the documentation that explains how to write an application 
  based on wpcap.dll.
  
- Removed some useless files in the source tree (these files that are 
  automatically generated by the build process or no longer in use).
  
- Removed some useless files from the developer's pack.
  
- Bug fixing:
  + Fixed a bug by which the caplen field of a WAN packet was set to a
    random number (usually 0 for the first packets of a capture). This
    was causing WinPcap not to work at all on dialup/VPN adapters. 
  + Fixed a bug in the BIOCSETOID/BIOCREQUESTOID code: in one error 
    management path we were not releasing the NDIS binding context 
    with NPF_StopUsingBinding(). 
  + Fixed a bug in some samples (when compiled under VS2005): 
    localtime() accepts a time_t variable, which happens to be a 32bit
    value with VS6/VS2003, and a 64bit value when compiled under 
    VS2005. 
  + Fixed a bug in some samples: added a const qualifier for the 
    packet data returned by pcap_next_ex(). 
  + Fixed a couple of bugs in the remote capture code that were 
    causing wpcap.dll to fail when a read timeout occurred, and a 
    failure to use the remote capture deamon (rpcapd) when compiled on
    a big-endian machine. 
  + Added the usual #ifndef/#define and #ifdef _cplusplus stuff to 
    win32_extensions.h 
  + Minor fixes to the samples. 
  + Minor fixes to avoid some compilation warnings under Cygwin. 
  + Minor layout fixes to the documentation.
