Quite a few changed have been made to the plugin, so you will have to update lang.yml manually.
You can also rename or delete any of the files, to generate new ones.

config.yml
lang.yml

The plugin has been tested on 1.20 and should work as usual.
(Same goes for older versions of DCM)
(Do note that I've been testing on an experimental version of Paper, so there may be errors I do not know about, since Spigot/Paper 1.20 is in the early stages)

- PlaceholderAPI support!
You can now use other plugin's placeholders using PlaceholderAPI.
I haven't tried adding PlaceholderAPI to my plugins before, so please message me if something is off

- Changed how commands are handled.
They should now be castable via other plugins.

- Reworked how our own placeholders work to support PlaceholderAPI, and I've changed how the lang.yml file is layed out.
The placeholder %s has been removed from all messages.

- The config value "timestamp" has been removed and replaced with the placeholder %timestamp%

Ignore the LuckPerms hook message for now.
LuckPerms is no longer used due to PlaceholderAPI, but is still being hooked if available.
This'll be removed soon.
