MikeL - I picked up the announcment from Gustavo's blog, and got the download link from Lasse Korpela's blog entry which also turned up on Planet Maemo - I now see Lasse's blog has been edited to remove the download link.

The original blog from Gustavo didn't make it clear this was a closed beta - want me to remove the download link from my post or add a warning? The update from Lasse is that all bugs should be reported on #maemo, so I think the message is don't install this unless you intend to help by discussing bugs on #maemo and if not, just uninstall Canola beta-2. If it works for you, great.

EDIT: I've removed the link anyway as I suspect it was the wrong thing to publicise.
