[Pvfs2-developers] PVFS2 release: pvfs2-1.5.0

[Sam Lang]

Hello!

The PVFS2 development team is pleased to announce PVFS2 1.5.0.

Notable changes in this release:

* Infiniband module supports OpenIB as well as Melanox.
* Optimized metadata access performance with a new metadata storage  
format.
* Better support for 64 bit platforms and 64bit/32bit mixed  
environments.
* Epoll is enabled by default
* Optimizations for the TCP module: Allow socket buffer sizes
    and window sizes to be changed dynamically.
* Support for linux kernels 2.6.16 and 2.6.17.
* Many internal improvements and bug fixes.

A more complete summary can be found in the ChangeLog.

Note that this release changes the storage format, so storage spaces  
created with 1.4.0 or older must use the pvfs2-migrate-collection  
utility after 1.5.0 has been installed.  See the pvfs2 faq item for  
further info:

Note also that this release changes the network protocol:  when  
upgrading, you'll have to ensure your clients and servers are  
synchronized.
