OpenAFS 1.5.53 released (Production Version for Windows including UNICODE; Test Version for other platforms)

1.5.53 is the recommended production-ready release of OpenAFS for
Microsoft Windows users.  It supports all Microsoft Windows operating
systems from Windows 2000 through Windows Vista SP1 and Windows Server
2008 including both 32-bit and 64-bit architectures.  The 1.5.53
release continues the recent efforts at optimizing the performance of
the Windows client and improving its scalability.

In the 1.5.53 release of OpenAFS for Windows, each of the AFS Client
Service, the AFS Explorer Shell Extension, and the command-line tools
are UNICODE character set enabled.  No longer is OpenAFS restricted to
accessing file system objects whose names can be represented in the
locale specific OEM code page.  This has significant benefits for end
users.  Most importantly it permits non-Western languages to now be used
for file system object names in AFS from Microsoft Windows operating
systems.  Now that Unicode names are supported, Roaming User Profiles
and Folder Redirection will no longer fail when a user attempts to store
an object with a name that cannot be represented in the OEM code page.

For UNIX, Linux, and MacOS X the recommend production-ready release of
OpenAFS is 1.4.7.  The 1.5.53 Windows client is fully compatible with
all AFS server versions.

Windows:

This production release is a major release.  Changes since 1.5.52 include:

 * Many potential deadlock conditions due to out of order
   lock acquisitions have been corrected

 * A race condition resulting in an undercount on the
   cm_scache_t reference counts has been corrected

 * An empty string when sent as an ioctl path is now properly
   interpreted as meaning the current directory.  This affects
   "fs lsm", "symlink list", etc.

 * Fix smb string parsing differences where the smb protocol
   documentation does not match the actual Windows implementation

 * Random access denied errors fixed

 * A file server lock synchronization issue was corrected in
   SMB NTCreateX and NTTranCreate operations.  This bug prevented
   properly operation when loading roaming profiles.

 * Fix a heap overwrite error during server probe operations if
   a new server is added while a probe operation is in progress.

 * Fix an LSA memory leak that was the result of an LSA error.

 * Do not leak cm_cell_t objects if the VLDB server lookup fails.

 * Only initialize rx mutex/lock objects once.

 * Do not nul terminate the AFS volume name when reported to
   Windows

 * Improve VNOVOL error handling.  Prevent updated vl information
   from being destroyed immediately after it was acquired.  This
   bug prevented proper fail over when volumes are moved or
   removed from a server.

 * Remove volume id from the server volume list in response to
   VMOVED and VNOVOL errors.

 * "fs flushXXX" commands now destroy locally built B+ directory
    trees.

 * Prevent mixture of locally modified directory pages and file
   server directory pages.

 * Fail over to alternate vl servers if a ubik error is returned.

AIX:

 * AIX 6 is now supported.

FreeBSD clients:

 * FreeBSD 7 is now supported.

Linux clients:

 * cache bypass is now supported.

 * 2.6.x kmod compilation now uses kernel compile options always.

 * Support through 2.6.27.

MacOS clients:

 * Show more space free so Finder doesn't get confused.

Solaris 10 server:

 * Default to namei rather than inode.

All UNIX clients:

 * Disconnected AFS now supports read-write mode.

 * volserver now builds correctly.

All systems:

 * rx avoids many packet leaks.

 * Demand Attach fileserver tries to avoid issues tracking
   offline status of volumes.

 * rx jumbogram disabling now works (and is the default).

This release is the recommended production release for all
Microsoft Windows environments.
