In this release:

• Updated Chromium OS manifest to release-R77-12371.B branch and Chromium to 77.0.3865.41
• Default credentials: chronos / test0000

Known issues

• On initial boot there is a brief period of unresponsiveness where the system is awaiting for HDMI input signal
• No hardware acceleration support for decoding video streaming, yet. TODO
• cras will sometimes cause 100% CPU usage hang when switching between videos playbacks. Reset it by: sudo restart cras
• This release is of a test build, which is by design very insecure (for any production environment), as quoted from Viper: "You must never log in to them with credentials you care about. It will automatically start ssh with root access via well known credentials."
