I am pleased to announce the release of rainbow-0.8.6. Rainbow implements
portions of the isolation shell described in the Bitfrost threat model and
security architecture.

The key differences between this release and its predecessor include support
for garbage collection of uids, ui sugar for resuming uids, bug fixes to the
resume logic, and a simplified singly-linked list library.

This release was made possible by encouragement and suggestions from Sascha
Silbe, Bernie Innocenti, and Benjamin Mako Hill. It has been (minimally) tested
on Debian Sid, Ubuntu Karmic, and Fedora Rawhide and has been packaged in
Fedora Rawhide for your convenience.
