v0.13.0

Added

• Ability to reverse global left and right audio channels (new configuration file option) to work around broken hardware (issue #307).
• Support for CP2104 (and possibly other members of CP210x family) USB serial devices (issue #305). Thanks to @gritd and @ajhuitsing for reporting/finding a solution!
  • This is currently achieved by applying a temporary patch to Circle to remove a part number check in the CP2102 driver.

Changed

• Update to circle-stdlib v16/Circle Step 45.1.
• Update ARM toolchains to 11.3.rel1.
• Update to libmt32emu v2.7.0.
• Update to FluidSynth v2.3.1.
• Update to inih r56.
• Volume up/down buttons in the simple_buttons control scheme now repeat and accelerate when pressed and held (issue #323).
• Updater: config.txt is now replaced on update, however the avoid_warnings setting is preserved (the only setting that matters to most users).
• Updater: improved error handling.
• Installer: less often-selected Wi-Fi countries have been moved to a separate list.

Fixed

• Incorrect I²C clock speed with recent Raspberry Pi firmware versions (issue #292). This was caused by core clock frequency scaling by the GPU firmware. Changes to config.txt have been added to ensure the I²C clock is stable by locking the core frequency to 250MHz. The newer Raspberry Pi firmware has been restored.
• Some USB MIDI controllers which make use of interrupt endpoints would not be usable (e.g. some Novation models).
• Installer: invalid Wi-Fi countries removed from list according to driver source.
• Installer: if using a wpa_supplicant.conf copied from a MiSTer system, invalid lines are now removed (e.g. "ctrl_interface") as they will fail under mt32-pi.
