File Release Notes and Changelog

Release Name: 1.1.0-preX

This is the first development release of what will eventually become
EVMS 2.0.

This is currently a pre-release, so only the source code package is 
available. Kernel patches are available for 2.4 kernels up to 2.4.19-rc3,
and for 2.5 kernels 2.5.25 and 2.5.27. The EVMS kernel code is still being 
updated for the 2.5 kernel, and currently the OS/2, BBR, and Snapshot 
plugins do not compile on 2.5.

Also, since this is a pre-release of a developement package, you should
use the appropriate level of caution when using this release! It contains
several new features which have not undergone extensive testing yet!  In
other words, you probably shouldn't use this version on any critical
systems.

*** Important Information About The New Major Number ***

As of release 1.1.0-pre4, EVMS has been assigned a new major number.
The old major, 63, was reserved for experimental drivers. The new
major, 117, will be assigned to EVMS permanently.

Please see http://evms.sf.net/new_major.html for details on how the new
major number might affect you.

If you encounter any problems or bugs, please send email to the EVMS 
mailing list (evms-devel@lists.sf.net).
