vDEV-1.9.5 - Advanced Math & Performance Update

This version introduces dynamic hardware profiling and completely rewrites the core movement checks for high-performance servers.

Additions & Changes:

• Added Smart Hardware Profiling. The plugin now runs a short startup benchmark to test your CPU. Fast processors will automatically use the new strict vector math, while budget or ARM hosts will fall back to the classic lightweight checks to preserve TPS.
• Added the /ac perf <high|light|auto> command, allowing server owners to manually override the hardware profile.
• Integrated native Bedrock support via the Geyser API. Bedrock players automatically receive a slight leniency buffer on movement checks to account for packet translation jitter, reducing false positives.
• Rewrote the Speed check for high-performance mode to use Time-Delta calculations. It now measures the time elapsed between packets rather than just flat distance, preventing players from saving up lag to teleport.
• Added Vector Gravity Prediction to the Flight check. It now calculates the exact expected Y-velocity using Minecraft's internal gravity formula to catch hover and slow-fall cheats.
• Upgraded the Phase check with Vector Ray-Tracing to detect horizontal clipping (H-Clip) through walls, even if the start and end blocks are both air.
• Implemented a strict Terminal Velocity limit to instantly block vertical downward clipping (V-Clip).
• Cleaned up the Maven pom.xml dependencies to ensure the plugin stays lightweight without pulling in unnecessary Geyser UI libraries.
• Added customizable combat timer UI positions (ActionBar, BossBar, Subtitle).

-# I have been hacking away at some very cool new features, this took forever and still is only a dev build as i guaranty you there is a bug somewhere

DEV-[1.9.4.6] - 2026-03-07 Build THIS IS A DEV BUILD, EXPECT BUGS AND BE WARNED WHEN USING Fix: Added grace period after elytra unequip to prevent false speed kick violations. Players landing from flight now have 7 seconds (configurable) of exemption from speed checks to allow residual velocity to dissipate naturally. Dev: Implemented glideEndTime tracking in PlayerData to monitor when players stop gliding. Dev: Made elytra grace period duration configurable via speed-check.grace-period-ms in config.yml.

Version 1.9.4.5 Fixed phasing punishing normal people Version 1.9.4 Added phasing detection so if someone phases through a wall it will rubber band them back. Fixed some false detections and made some peformence updates

Fixed a false detection where if a player was using a wind burst mace they got kicked for flying
