   * Introduce `AddPlayerBuffWhitelist` (replacing `WhitelistBuffMaxTime`), which allows us to specify the maximum amount of ticks a buff can be applied for, and if it can be applied without the target being in PvP.
   * When rejecting from `OnPlayerBuff`, instead of sending a `PlayerAddBuff` packet with the rejected buff (essentially a no-op, as the sender implicitly applies the buff to the target, and causes desync as the buff was rejected), send a `PlayerBuff` to re-sync the target's buffs, without the buff we just rejected.
 * Added new tile provider. Use `-constileation` or `-c` to use it. Constileation is an alternative tile provider to Tiled and HeapTile. (@SignatureBeef)
+* Fixed an exploit with grass mowing not removing hanging vines. (@punchready)
 
 ## TShock 4.5.18
 * Fixed `TSPlayer.GiveItem` not working if the player is in lava. (@PotatoCider)
