Pre-releases of the Vivid Vervet are *not* encouraged for anyone
needing a stable system or anyone who is not comfortable running into
occasional, even frequent breakage. They are, however, recommended for
Ubuntu flavour developers and those who want to help in testing,
reporting and fixing bugs as we work towards getting this release
ready.

Beta 1 includes a number of software updates that are ready for wider
testing. This is quite an early set of images, so you should expect
some bugs.

While these Beta 1 images have been tested and work, except as noted
in the release notes, Ubuntu developers are continuing to improve the
Vivid Vervet. In particular, once newer daily images are available,
system installation bugs identified in the Beta 1 installer should be
verified against the current daily image before being reported in
Launchpad. Using an obsolete image to re-report bugs that have already
been fixed wastes your time and the time of developers who are busy
trying to make 15.04 the best Ubuntu release yet. Always ensure your
system is up to date before reporting bugs.
