This update is for Spigot/Minecraft 1.13 and 1.14, and has been compiled with Spigot API 1.14.3.

This update contains an option to display a player's remaining double-jumps in the scoreboard. This needs to be enabled in the config:
There is also an option to remove a player's purchase if the player leaves the arena before the game starts. If the player rejoins the arena, he/she can again purchase any shop item, money permitting. The default is false.
The custom knockback effect of snowballs, added in version 8.1, is now configurable between 0 and 5. Zero will have no knockback effect on a player, while 5 will have a large knockback effect. The default is 2.

The player's monetary balance can be displayed in the shop by using the item in the final inventory slot of the shop. If your shop is currently full, then you can increase the size in config.yml, as this item will overwrite anything in the final inventory slot. The text displayed by this item can be translated or changed in messages.yml. The item itself (default GOLD_INGOT) can be set in config.yml.
