[Pvfs2-developers] PVFS2 release: pvfs2-1.4.0

[Robert Latham]

Hello!

The PVFS2 development team is pleased to announce pvfs2 1.4.0.  We've
slipped a bit on our bi-monthly schedule, but we've put the extra time
to good use.  

Notable changes in this release:
- A new optimization we call SIO (small io): small I/O requests will
  be piggybacked along with the initial communication between server
  and client.  It's like MPI eager mode, but for I/O.
- A new atribute cache, built upon a generic caching infrastructure.
  There are now a lot more tuning knobs for cache behavior. 
- Many bug fixes, especially for zero-fill and truncate

A more complete summary can be found in the ChangeLog.  This release
changes the network protocol:  when upgrading, you'll have to ensure
your clients and servers are syncronized. 

This release represents 119 changesets over 10 weeks.  Diffstat
