Microsoft Windows:

This production release is a major release.  Important changes since
1.5.65 include:

 * Official support for Windows 7 and Server 2008 R2

 * Prevent a file server bug (FetchData returning an
   invalid length instead of zero) from causing an
   "unexpected network error" when writing to files.

 * Promote DNS SRV records as superior to DNS AFSDB
   records.  Support arbitrary port numbers for vldb
   servers.

 * Add AFSVolSync based .readonly "whole-volume callback"
   support.  With this functionality, multiple objects from
   a .readonly volume can have their status validated by
   issuing a single RXAFS_FetchStatus RPC.

 * Remove drive mapping functionality and service start/stop
   from afscreds.exe.

 * Remove drive mapping functionality from afs_config.exe.

 * Use {HKLM,HKCU}\SOFTWARE\OpenAFS\Client  DWORD  "ShowMountTab"
   to restore access to drive mapping functionality in afscreds.exe
   and afs_config.exe.

 * Adjust SMB error return codes to avoid returning
   STATUS_TIMEOUT which results in the SMB redirector
   disconnecting.

 * Network Identity Manager OpenAFS Provider now provides its
   own "AFS lock" notification icon to report the status of
   "have tokens, have no tokens, service not started, service
   started but inaccessible".  Hovering over the icon lists the
   cells for which tokens exist (if any) and the OpenAFS version
   number.  Double-clicking executes the Network Identity Manager
   default action.

 * Prevent pioctl calls from retrying indefinitely when a sharing
   violation error occurs.

All platforms:

 * Avoid calling exit() in library code.

 * Add rx window size and peer timeout tuning APIs.

 * Correct rx peer timeout handling to disallow 0ms timeouts.

 * Correct calculation of rx RTT by disregarding retransmitted
   packets.

 * vos manpages updated to reflect changes in recent versions.

 * GNU-style long options (e.g. --cell) are now supported in all
   commands.

 * fs listacl can now print a command to recreate the current ACL.

All UNIX clients:

 * Correct a condition which could discard the error from initializing
   a fetch request.

 * Avoid using invalid references to afs_Conn connection structures,
   and thus potentially producing invalid data when a retry is needed.

 * SRV records are now supported for discovering AFS servers.

All servers:

 * Fix a race on transaction objects in the volserver which can
   cause a crash.

 * Avoid destroying and setting to NULL the callback connection when it
   could still be being used.

 * Correct unlink handling in salvager.

 * Improve error messages due to I/O errors in the volserver.

 * Correct an issue which caused converted RO to RW volumes on namei
   fileservers to not come online immediately.

Linux:

 * Correct writepage behavior.

 * Fix error code handling in the writepage code.

 * Avoid leaking page locks, which could potentially hang a machine.

MacOS X:

 * Preferences Pane improvements.

HP-UX:

 * Avoiding attempting to handle critical signals in servers, so that
   core file handling works correctly.


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