Performance Improvements

• Reduced CPU, memory, and disk workload:
  • Server identity is now derived once per window.
  • Key snapshots and binding rebuilds occur only when changes are detected.
  • Settings writes are coalesced onto a background thread and written atomically.
• Chunk scheduling is intentionally left to vanilla Minecraft, Sodium, and Lithium.
• The poller reduces its frequency to 20 Hz in menus and while paused, while maintaining full polling frequency in-game.
• Added a new Performance Engine section in settings, providing controls for:
  • Individual module switches.
  • Check intervals.
  • Write delays.
• No FPS improvement is claimed because no measurements were taken in a running client.

Input Correctness (4.0.1-beta)

• Fixed COOLDOWN CPS mode: the minimum click interval was incorrectly multiplied by nanoseconds twice, resulting in an approximately 15-hour delay. It now correctly uses 35 ms or one window divided by the configured cap.
• Clicks inside chests and inventories no longer execute in the game world.
• Right-click interactions with blocks work again instead of always using the held item.
• The swap-offhand key no longer accidentally consumes food or places blocks.
• A single failing action can no longer crash the tick loop.
• Safe Mode can disable the input layer.
• Jump actions triggered by the mod now execute exactly once.
• Keys held during a pause no longer generate fresh presses when the game resumes.
• Entity attacks now verify that the target is alive and within reach.
• Replay no longer inflates hit counts, CPS, or click sounds.
• Configuration improvements:
  • Correct directory handling for import/export.
  • Correct schema version.
  • Bounded event log.
  • Locked CPS window.
• Overlay scaling now correctly scales text as well.

Keyboard Routing (4.0.2-alpha)

• Fixed the issue where pressing Space in chat caused the player to jump.
• Screen state is now recorded using the game's own screen-opening method.
• Queued input events are discarded when a screen opens.
• Added an opt-in Custom Keyboard ALPHA handler:
  • Protected by a warning screen.
  • Displays a red banner while active.
  • Disabled by default through custom_keyboard_handler=false in the configuration.
  • Does not modify vanilla key bindings.
  • Does not cancel input from other mods.

Stability Audit (4.0.2-stable → 4.0.3-stable)

• Replay now waits while a screen is open instead of losing events behind it.
• The poller re-seeds its edge detector when no key source is available.
• Initialization and the tick loop now catch Throwable, preventing linkage errors from escaping into every tick.
• Startup logs now identify which screen hook was applied.

4.0.2-stable Withdrawal

Version 4.0.2-stable was withdrawn because three Mixin accessors exposed non-private static methods, which Mixin rejects. This caused the Minecraft client to crash during loading.

Fixes

• Moved the affected helper methods into MixinAccess.
• Added a build test that fails if any mixin declares non-private static methods.
