Counter AntiCheat

New

• New tick-exact checks for scaffold, nuker, surround, silent swaps, and anchor and bed aura.
• Stepping up a full block in one tick is caught.
• Killaura and reach checks now also cover mobs: aim, attacking from inside a menu, attacking while blocking, and reach on mobs that stand still.
• Killaura is now checked while riding and during elytra boosts.
• High jump is caught on the takeoff tick.
• Optional fast punish for killaura: add post_tick and multi to proof and they punish in fewer flags. Off by default, leave it off if your proxy runs ViaVersion.

Improved

• Players on clients newer than your PacketEvents build now get the right physics.
• Timer can no longer hide behind right-click spam or teleports.
• Phase can no longer switch itself off by placing or breaking blocks.
• Wind charge, pearl and vehicle exemptions are shorter and much harder to abuse.
• Mob reach and hitbox checks keep working while the player lags, and on killing blows.
• Anti knockback is now checked properly at low ping.
• High ping players can no longer dodge a punish by going quiet or relogging. A single real lag spike is still let off.
• Less work per move and per packet, and spectators skip the physics engine.
• The database reconnects on its own and never counts a flag twice across a network.

Fixed

• Older clients on networks running ViaVersion on the proxy no longer flag killaura.
• Fake Bedrock IDs and a fake Geyser brand no longer skip checks.
• Plugin area damage (mcMMO, custom enchants) no longer counts as reach.
• Soul speed on honey and sneaking off ledges no longer flag.
• Memory leak when fighting lots of mobs.
• No flag data is lost on a crash or shutdown.
• A typo in config.yml on first start no longer makes alert only checks punish.
• Alert history now shows in each staff member's own language.
• Unfreezing an offline player now works.
