[3.0.0] - 2026-05-23

🎉 Major Release — Minecraft 1.21.11 Full Port

This release is a complete port and overhaul targeting Minecraft 1.21.11 with Fabric Loader 0.19.2 and Fabric API 0.141.3. All known bugs from 2.x have been resolved and several new features have been added.

---

🔧 Build System

• Upgraded fabric-loom from legacy version to 1.14.10 — the latest stable release supporting MC 1.21.11
• Fixed Gradle plugin resolution — added resolutionStrategy in settings.gradle to correctly resolve fabric-loom from Fabric Maven (https://maven.fabricmc.net/)
• Gradle wrapper pinned to 9.5.1 for compatibility with loom 1.14.10
• Java toolchain set to Java 21 (required for MC 1.21.11)

---

🐛 Fixed

Compilation Errors (MC 1.21.11 API Changes)

• KeyBinding category API breaking change: KeyBinding constructor no longer accepts a raw String for the category parameter. Updated both keybindings (key.inputbooster.options, key.inputbooster.toggle) from "key.categories.misc" → KeyBinding.Category.MISC to match the new record-based category system introduced in 1.21.9+
• DrawContext.drawBorder() removed: Method no longer exists in 1.21.11. Replaced with four explicit drawHorizontalLine / drawVerticalLine calls to draw the CPS graph border in InputBoosterScreen

Runtime Bugs

• Black overlay covering the screen: DebugOverlayManager was calling ctx.fill() to draw a semi-transparent black background (0x8B000000) behind each HUD text line. In 1.21.11, DrawContext.fill() renders without proper alpha blending, producing a solid black stripe across the entire screen. Removed the background fill and enabled text shadow (drawText(..., true)) for readability instead
• "Burst Mode ended" message looping on screen: BurstModeManager sent the action bar message inside the tick loop without a sent-flag guard, causing it to fire every tick rather than once. Fixed with an endMsgSent boolean flag that prevents the message from repeating
• Burst Mode triggering immediately on game load: lastFps was initialized to -1, causing a massive artificial FPS drop on the very first tick which immediately triggered burst mode. Fixed by initializing lastFps to 0 and only comparing when FPS is stable (> 10)
• lastFps updated with invalid zero FPS values: FPS reads of 0 during early load were being stored as lastFps, corrupting future drop calculations. Fixed by only updating lastFps when fps > 0

---

✨ Added

• BurstModeManager — endMsgSent flag: Ensures the "Burst Mode ended" action bar message is shown exactly once per burst cycle
• ProfileManager system: Saves and loads named poll rate profiles, allowing players to switch between preset configurations
• SessionStats tracker: Tracks per-session statistics including total hits, recovered inputs, average CPS, and session duration
• LatencyProfiler: Measures and reports input-to-frame latency in the HUD overlay and F3 debug screen
• In-game config screen (InputBoosterScreen): Full GUI screen accessible via keybind (default O) for toggling all features and adjusting poll rate without restarting
• Combo key presets (Ctrl+1 through Ctrl+5): Instantly switches poll rate to 100 / 200 / 350 / 500 / 1000 Hz in-game
• Burst Mode (BurstModeManager): Automatically spikes poll rate to 1000 Hz for 3 seconds when FPS drops more than 20% in a single second, ensuring zero inputs are lost during lag spikes
• CPS graph in settings screen: Visual bar chart of recent CPS history with color-coded bars (green / yellow / red based on proximity to the CPS cap)
• Action bar notifications: Optional in-game messages for burst mode activation/deactivation and poll rate changes via combo keys

---

🔄 Changed

• HUD overlay background replaced from opaque ctx.fill() box → text shadow for clean rendering on all GPU/driver combinations
• Poll rate auto mode now uses a 5-tier FPS threshold system (≤20 FPS → 500 Hz, ≤30 → 400 Hz, ≤60 → 200 Hz, ≤120 → 150 Hz, 120+ → 100 Hz)
• Config file expanded with new keys: burstModeEnabled, showActionBar, comboKeysEnabled, maxCps, debugMode
• Mod version bumped to 3.0.0 across all metadata files

---

🗑️ Removed

• ctx.fill() background behind HUD lines — caused black overlay bug on 1.21.11
• String-based KeyBinding category — replaced with typed KeyBinding.Category record
• DrawContext.drawBorder() call — method removed from MC 1.21.11 API
