[OpenAFS-announce] OpenAFS 1.3.80 released

[Derrick J Brashear]

OpenAFS 1.3.80 is now available for download from the openafs.org web
site.

For Windows, 1.3.80 is the new stable release.  This release continues the 
substantial improvements provided to the community since November 2003.  Thanks 
to a contribution from Sine Nomine Associates of work performed by Secure 
Endpoints Inc. OpenAFS for Windows now supports:

  * a persistent cache of up to 1.2GB
  * cache manager debugging
  * long term UUIDs
  * correct server failover and callback revocation
    processing.
  * multi-domain Windows forests with cross realm trusts to
    MIT or Heimdal KDCs
  * the ability to obtain tokens for multiple cells via OpenAFS
    integrated logon
  * improvements to directory search processsing
  * the ability to obtain tokens via cross-realm trusts when using the
    AFS systray tool
  * new @sys names
  * many many bug fixes.

Please see the afs-changes-since-1.2.txt file on the release page for
complete details.

Special thanks are issued to MIT's IS&T division for their efforts in
developing a stress test which has been used continuously over the last
two months to identify defects in the OpenAFS for Windows client.  90%
of the work of fixing a problem is being able to reproduce it.  Without
the stress test and the testing environment The OpenAFS Project would
not be capable of producing such a high quality product.

The performance of the OpenAFS for Windows client has improved over
the last eighteen months.  The percentage improvement of OpenAFS for
Windows 1.3.80 over 1.2.10 are as follows:

   crypt mode: writes:  54%; reads: 125%
   clear mode: writes: 143%; reads: 263%.

The percentage improvement of OpenAFS for Windows 1.3.80 over IBM AFS
3.6.2.53 are as follows:

   clear mode: writes:  31%; reads:  35%.

For those of you who have been burned by the use of AFS on Windows in
the past and are waiting for the 1.4 release to re-evaluate the combination of 
Windows and AFS, the 1.3.80 release for Windows is a release candidate for the 
1.4 release.  When the Unix/Linux/MacOS platforms are ready for a 1.4 release, 
new Windows binaries will be produced including any available bug fixes.  There 
are no additional changes planned for Windows before the OpenAFS 2.0 release.

For UNIX, 1.3.80 is the latest version in the 1.4 release cycle. Starting in 
1.3.70, platforms with pthreads support provide a volserver which like the 
fileserver and butc backup system uses pthreads. Solaris versions 8 and above, 
AIX, IRIX, OpenBSD, Darwin, MacOS and Linux clients support large (>2gb) files, 
and provided fileservers have this option enabled. HP-UX may also support large 
files, but has not yet been verified. We hope sites which can do so will make 
use of 1.3.80 on their UNIX platforms and provide feedback to help us fix any 
remaining issues before 1.4 is released.

The UNIX client and server includes a number of updates, including 
many client fixes for Linux 2.6. There is also a fix for support in the 
fileserver which has existed only in previous 1.3 versions for breaking 
volume callbacks following release out of band of the release; All sites 
running OpenAFS 1.3 fileservers are advised to upgrade to 1.3.80.
