DISC's beta firmware v2.04

Note: v2.04 is a beta version, and updating to this new firmware is a bit of a hassle. You’ll need to manually update locally to v2.03 (also a beta) first before you can do an OTA update to v2.04. The download link for v2.03 can be found in my reply below. I didn't share v2.03 earlier because it was pretty buggy and had some serious issues. However, I’ve been testing v2.04 for 2 days now, and it seems stable so far. If you find the update process too tedious or don't want to risk it, you can just wait for the official firmware release, which is expected to roll out in the next few days.

Below are the release notes for v2.03, which should be the same for v2.04.

1. Added Bluetooth receiver mode
2. Added gapless playback
3. Added sorting toggle between Artist and Album Artist in category playback
4. Added album category sorting by genre and display of all tracks in category playback
5. Fixed the issue where tracks could not be added to Favorites or My Playlist after upgrading
6. Fixed playback stuttering issues with some M4a tracks
7. Other bug fixes and performance optimizations
8. Note: When using the Bluetooth receiver function, it is recommended to turn off Wi-Fi first to avoid a suboptimal experience.
