Previously, if an HDMI display was connected at boot time when composite was enabled, the firmware FB would get "stuck" and a login console would not appear on either HDMI or composite. With the change, a console will now appear, typically (invariably?) on HDMI (just as happens with HDMI + DPI). This may be helpful when booting to CLI when composite was enabled accidentally and cannot be viewed. The old behaviour can be reinstated by adding the "nohdmi" option.
