v.0.58.0

Added

• HDMI-CEC. On boards with a TC358743 capture chip the device now talks
  over the CEC line of the HDMI cable. It acts as a TV, finds what is
  connected and shows its name, vendor and power state. From the console's
  new remote panel you can send remote-control keys, put the source to
  standby or wake it. Also in the API (/api/v1/cec), in runbooks
  (hdmi standby, hdmi wake, hdmi key <name>) and in Home Assistant.
  Only media boxes, consoles and the like speak CEC; an ordinary PC does
  not. What the source says about itself is under the HDMI icon at the
  bottom, and the remote button shows up only when a source answers. Tried
  with a Steam Deck in its dock: the name, the remote keys in the Steam menus
  and standby work; wake does not, SteamOS does not wake on CEC. Off with one
  switch in Settings → Power.
• Pointer lock in relative mode. While you are in control, the console
  hides your own cursor and sends only movements, so the target's cursor is the
  only one on the screen. Esc gives it back. This is what SteamOS in game mode
  needs: an absolute pointer does not move there.

Changed

• The buttons under the picture are icons now: touch, fit / stretch / 1:1,
  select text, copy text.

Fixed

• Clicks in relative mode moved the cursor first. They went out as
  absolute reports, so the target's cursor jumped to the browser's spot before
  every click.
• A Steam Deck was shown as Android. Steam re-reads the USB strings the
  way Android does. Android also re-reads the device's own name strings, and
  that is what the guess looks for now.
