New Special Build available for download at http://chromium.arnoldthebat.co.uk/special/Cx86OS_R42-6813.0-Special.7z. As per the previous build, this is cumulative so contains all the previous drivers.
Unfortunately, there is still no Broadcom support! Its a work in progress so bear with me…
In addition, the old versions of the special build can be updated from a new Dev Server by issuing the following command.
update_engine_client --update --omaha_url=http://chromebld.arnoldthebat.co.uk:9080/update
The only thing I have noticed not working too well is that extensions sometimes crash on login. It is a simple reload to add them back in again however..
Sleep/Restore on laptop lid close/open seems to work fine now as well.
