This update is for Spigot/Minecraft 1.13 and 1.14, and has been compiled with Spigot API 1.14.4.

Update 8.4 includes a number of bug fixes and some small improvements (see change log), the main one being the ability to remove any of the default shop items without them reappearing when the server restarts. This can be done while the server is running, the shop contents will be automatically refreshed.
I've added a new command /tr autojoin which will join the player to the first available arena.
When buying doublejumps in the shop, the scoreboard is now automatically updated to show the player's current total (assuming the option to display doublejumps in the scoreboard is enabled in the config).
