Quick answer
Which toucanLib release should I use?
toucanLib 0.5.0 targets 1.21.1 with Fabric. Installation on the client is optional. Installation on the dedicated server is optional. All 2 required mods have matching files.
Where it goes
Is toucanLib required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does toucanLib 0.5.0 need?
0.5.0. Change the file and its required mods may change too.
Install Architectury API, Fabric API first. We found matching files for this game-version and loader setup. 1 comes through another mod in the chain.
1 extra mod was pulled in by another dependency. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.
