Release notes for 0.27.7
v0.27.7: several fixes for features broken by TETR.IO updates

Changelog:
- Fixed custom sound effects, custom music, music graph hooks for TETR.IO β1.6.2
- Fixed several issues related to internal storage and tpse migrations: the hidden value of custom songs will no longer reset by itself, and will be properly set when importing older TPSEs
- Experimental, optional extended watermark showing enabled features in-game in the corner at all times - this may or may not stick around as a feature, and the toggle is currently listed only in debug mode
