Changes:

If you have the permission "MCSF.dontfilterme", (no one has this by default) messages will not be filtered for you.
Hex RGB support added for variables, the format is &#RRGGBB
Sign filtering is now relative to the player's view distance rather than the server's view distance which could be larger than that. Although, since this was recently added in 2018 if any errors were to occur because of it, it would default to the server's view distance instead.
Re-translation of de_de.yml (Thank you Xirado)
No longer requires ProtocolLib to be installed
- Without ProtocolLib although player chat will still be filtered, messages from other plugins will not.
