The EVMS team is announcing the next development release of the Enterprise 
Volume Management System, which will eventually become EVMS 2.0. Package 
1.1.0-pre4 is now available for download at the project web site:
http://www.sf.net/projects/evms

As with the previous pre-releases, only the source tarball is available for 
download. RPM files will be available when 1.1.0 is released. 

Also, please use the appropriate level of caution when using this version! 
There are several very new features which have not yet undergone extensive 
testing! In other words, you probably shouldn't run this version on any 
critical systems.

*** Important Note ***

As of this release, EVMS has been assigned a new, permanent major number: 
117. The previous major number, 63, was reserved for experimental drivers. 
Before using -pre4, please read the README_Upgrade_To_1.1.0 file included in 
the source package for details on how you might be affected by the major 
number change. You can also view these instructions on the EVMS web site at 
http://evms.sf.net/new_major.html.


Please report any problems or bugs to the EVMS mailing list: 
evms-devel@lists.sf.net.
