Despite using Linux myself, I've only included a Windows build, because that's what most people use and compiling tends to be less of a hassle for Linux users. I can prepare a Linux build if someone wants one, but unfortunately not macOS, as I don't have convenient access to a Mac. If you do want to compile from source, the corresponding source for this binary is identical to the SRB2_release_2.2.9 tag on Gitlab, with the exception of the "d_clisrv.c" file, which is included in the download.
Oh, and this works fine with vanilla clients; only the server needs to have the patch.
Thanks to Jerry for preparing the build as well as testing my fix on his server.
