So the engine and "data-otservbr-global" is out of date here? Latest relases are on Canary Git, true?
They are not out of date, they are uploaded released as windows.
For linux users, if you got the right vcpkg version in order to compile, you can compile it, since each day vcpkg is changing also canary, maybe you can compile today using the microsoft vcpkg, but maybe tomorrow no. ( It's important to fork the Vcpkg repo and canary repo, when you got the right version that allows you to compile, before you lose the version, since on vcpkg.json it's not writed the version of vcpckg it's impossible to download on github vcpkg the version in order to compile.
For canary or otserv global, check Canary Github, download zip, and follow steps to compile or download already compiled server.
