This update includes support for 1.19.
It also adds a new filter option for message types. More information can be found in the tutorials on Github.

What is sad is that in 1.19 the previously one packet was split into two. Therefore, system messages can no longer be assigned to where they originate, i.e. a player or the console. This applies for example to commands.
In 1.19, strangely enough, the normal chat messages sent by players are also sent by the system message packet, which means that they can't be assigned to a player, too. Currently, the only messages that can be assigned are these that originate from /say, /msg or /teammsg. I hope that this will be fixed in 1.19.1, but I'm quite sure they'll do it as they'll need it for the new report system.
