Void 2.9.0

Fixes

• AntiKB bypass (Grim #2371): a block change next to an idle player (inside the 0.03 movement zone) recalculated the pending knockback and explosions and could drop velocity the player had already been given, so the knockback was never enforced. Void now keeps the previous velocity when the recalculation finds nothing new.
• BadPacketsU: the expected Y of the "use item" placement packet is now compared as the raw 12-bit value sent by the client, so it no longer false flags when PacketEvents decodes positions in the pre-1.14 format (older servers or unrecognised server versions).
• AimSnapReturn: a flick-and-return move is no longer reused as the start of the next snap, so a single oscillation can't count twice. The hit counter is also reset when an exemption applies (teleport, vehicle, spectator).

Changes

• Bedrock players: Floodgate players (Geyser) are now exempt from the dedicated killaura checks (AimGcd, AimSnapReturn, AutoClickerD), since controller and touch input don't follow the mouse sensitivity grid.
• Added an unverified debug message for accounts named 22ix or using my UUID (unverified-dev-debug-greet to turn it off). It only shows basic Void info and grants nothing, it just helps me debug on users' servers.
