System requirements

Different distributions and releases ship with different fish versions.

The biggest source of problems is the compatibility between fish and tide (see Fish version compatibility)

To guarantee compatibility with the least possible maintenance effort, the latest fish version required, and the fisher plugins have been fixed to the specific versions known to work with the current fish version.

Therefore, only the following combinations are supported:

Platform/version	fish version	Package source
Debian 11	3.6.0	openSUSE Build Service
Debian 12	3.6.0	Official Debian repository
Fedora 37	3.6.0	Official Fedora repository
Ubuntu 22.04	3.6.0	fish PPA
macOS 10.15 Catalina	3.6.0	MacPorts
