The kernel in RC1 has been updated to upstream version 2.6.27.10 and the wl wireless driver has been updated to improve reliability. Some minor changes have taken place "under the hood" to address issues that were reported by individual testers.

Warren Woodford, the builder of SimplyMEPIS, says, " There have been lots of good updates from the upstream Debian developers. I know they are working very hard to finalize the release of Lenny, which is the foundation for SimplyMEPIS 8.0. And the MEPIS community has been hard at work, for example on the 8.0 manual, which has been submitted but was packaged to late for inclusion in this RC. I'm not sure if SimplyMEPIS will be ready by the end of the year, but we're working toward that goal."
