Alpha builds – R78-12476.0.2019_09_08

Alpha builds are now available for testing. These builds will pretty much always be near cutting edge release (in this case R78) and allow testing of new features before they are back ported into the released Special builds.
This will allow for a simpler mechanism to test and deploy new features without waiting for the cut of a specific release from Google to baseline in the main ChromiumOS repo.

Consider these builds even more alpha in quality therefore!

This particular build will not auto update but can be forced once the real R78 special version is deployed if desired.

When R78 special is ready, the upgrade process can be performed with the following command line after opening a shell prompt:

update_engine_client --update --omaha_url=http://chromebld.arnoldthebat.co.uk:9080/update
