[OpenAFS-announce] OpenAFS 1.5.75 released (Production Version for Windows; Test Version for other platforms)

[Derrick J Brashear]

1.5.75 is the recommended production-ready release of OpenAFS for
Microsoft Windows users.  It supports all Microsoft Windows operating
systems from Windows 2000 through Windows 7 and Windows Server
2008 R2 including both 32-bit and 64-bit architectures.  The 1.5.75 
Windows client is fully compatible with all AFS server versions.

1.5.75 is a necessary upgrade for sites which have taken the MS10-020 
update on Windows hosts, as this update did further validation of SMB 
traffic which was incompatible with previous versions of the OpenAFS 
client.

information on the status of the OpenAFS for Windows client.
