diskOS Disco! 2.6.2

Bluetooth headphones connect straight on AAC or LDAC: no switch, no pause. Plus a polished Bluetooth screen, a
clearer clock field, and back-swipe feedback on the track pop-up.

Bluetooth

• Born on the right codec. Until now every Bluetooth connection started on SBC and then switched to AAC or LDAC,
  which rebuilds the link: a short silence on the first song, or a song waiting a moment before it starts. Now Disco
  remembers which codecs your headphones support, and the next time Bluetooth starts it sets up the connection on
  your chosen codec from the first moment (with your LDAC quality: Mobile, Standard or High). Nothing to switch,
  nothing to wait for.
• Disco marks each pair with its known-good codecs: a codec that really ran on them (confirmed by Bluetooth
  itself) counts as good; one that didn't come up isn't insisted on next time.
• The first time you use a pair (or after choosing another codec), it works as in 2.6.1: start on SBC, switch once.
  As soon as the headphones are switched off, Disco gets ready, so their next connection starts straight on the
  right codec. Switched off and on again quickly, they're switched up again at once rather than staying on SBC.
• "Connected: FiiO EH11 / LDAC": the pop-up now names the headphones and the codec actually running, once the
  codec is settled, also when headphones reconnect by themselves.
• The Bluetooth screen keeps up: switching your headphones off or on while the screen is open now updates the
  list at once (it used to keep showing "Connected - LDAC" until you reopened it).
• Other headphones are safe: connecting to a pair that isn't known to support that codec sets Bluetooth up the
  normal way first, so it always has sound.

Bluetooth screen

• One clear line at the top: "Connected to FiiO EH11 - LDAC", in each theme's own font; long names scroll.
• Bigger rows and larger hint text ("Tap to connect", "Connected - LDAC"), and less empty space at the top, so the
  list has more room. Same elements, same places; the Wi-Fi screen is unchanged.

Clock field (Disco, Squash, Null)

• A touch bigger and clearer: the Wi-Fi, Bluetooth and battery icons, the clock (Disco, Squash) and the weather,
  all still inside their field.
• New: Settings › Display › Music screen › Music information › Clock and info, below Show clock:
  • Battery percentage: the level as a number (67%) next to the battery icon. Off by default.
  • Weather: the weather under the clock. On by default; off, tapping the clock no longer opens Weather.
• Null: when the menu slides in and the title moves up, the clock now fades out together with the weather.

Smaller things

• Back-swipe feedback on the track pop-up (tap the title on Music): the back arrow now follows your finger as on
  every other screen, and the pop-up closes when you let go with it armed.
• Ring and Braun: development is frozen. They keep working and get fixes that apply to every theme, but no new
  changes; the clock-field changes are for Disco, Squash and Null.

Testing: an independent review of an earlier 2.6.2 build found five issues; all are fixed and covered by
tests. The idea was tested by hand on the maintainer's Disc: started this way, LDAC headphones connected
straight on LDAC and stayed on it through playback. The automatic version is covered by tests but was not yet
tried on a Disc before release. Bluetooth codec choices still apply on firmware V2.57 only.

Installing and updating

• Already on diskOS Disco! 1.4.1 or newer? Update from the SD card: download mq_ui, sign it with your own
  keys and copy the diskos-update folder to the card (how). Your settings, music and stats stay.
• New install? Start from FiiO's stock V2.57 firmware (recommended). Installing over upstream diskOS or
  another diskOS build is not supported and can be buggy; restore stock first. See Install.
• Windows: Unsupported, but working as intended: confirmed several times by users, installs and SD updates included.

After updating

• Settings > System > About shows 2.6.2.
• The new version starts as a trial: play some music or tap Keep to keep it. If it doesn't start properly,
  the Disc goes back to the previous version by itself, or choose Go back.
