Changelog

v4.1.0

Modern UI Integration

  • New wizard page for configuring Modern UI features
  • Toggle Custom Font (Inter) — disabling reverts to the vanilla Minecraft font and requires a restart
  • Toggle Fancy Tooltips — rounded, styled tooltips with rarity-adaptive border colors
  • Toggle Startup Ding — sound effect played when the game finishes loading
  • Font values are backed up before clearing, and restored if the custom font is re-enabled
  • Confirm page now shows a restart warning when the font toggle differs from the current live state
  • Custom Font row in the summary is annotated with "(restart required)"
  • New /packcore modernui command with subcommands: font vanilla, font custom, tooltip on/off, ding on/off

Diagnostics

  • Full diagnostics report logged on every startup (modpack info, config pack, settings, runtime, system)
  • Crash reports now include a PackCore Diagnostics section with the same data as the startup log
  • New /packcore diagnose command — shows a compact report in chat with a click-to-copy button for easy sharing when reporting issues
  • New /packcore crashtest command — triggers a test crash to verify the crash report enrichment is working

Storage Design

  • Replaced the world-join command approach for toggling the Firmament storage overlay with direct reflection — the setting is now applied instantly without requiring a world join

Tab Design

  • SkyHanni compact tab list toggle now applied instantly via reflection instead of a delayed chat command on world join
