v0.8.50 — custom-stream preset buttons start from standby on their own

Fixed

Custom-stream preset buttons start from standby on their own. On SoundTouch speakers with firmware 27.0.6, pressing the button of a custom-stream preset while the speaker was in standby did not start playback: the speaker hung, the preset LED kept blinking and the power button was ignored, until SixBack sent the station again (the retries added in v0.8.23 and v0.8.48). The cause was the form in which SixBack hands these presets to the speaker. They now arrive in a form the speaker starts by itself: in tests all 17 presses — from standby, after more than a day in standby, and while another source was playing — started within 2 to 5 seconds without any help, on SoundTouch 10 (firmware 27.0.6 and 27.0.3) and SoundTouch 30 (27.0.6).

This applies to every build, including C3, C6 and ESP32, which have no watcher that could send the station again. On the ESP32-S3 builds the watcher stays in place as a fallback.

Important

Export your presets before you install any release older than v0.8.50. An older firmware does not recognise the new preset form, and the speaker then loses those preset slots.

No partition changes; the update can be installed online.
