Here's the full changelog for version 2.1, adding Simplified Chinese, several new features for translators, and a couple of bug fixes.
Major Changes
New language: Simplified Chinese (thanks to 'Witchcraft' Han)
Translation Tools
Implemented Simplified Chinese and Korean fonts.
In-game UI labels can now be translated into Japanese, Chinese, and Korean.
Custom translations can now toggle the option to display surnames before names (previously hardcoded for Japanese only).
Bugfixes
If dialogues are disabled in settings, epilogue, commentary, and translator-mode dialogues are no longer skipped.
Fixed Yuzu spawned during Mizuiro's bomb not being cleared after the animation ended, hopefully fixing a rare, user-reported crash.
