As can be seen, this is one of those project pages not intended to be useful to those who have not already become familiar with the subject in some other way.

Apparently this approach is so widely used in order to limit the number of new people that might become interested.

If Fish 3.6.0 were to catch on very widely or god forbid go viral, I can only imagine the maintainer would be as gravely disappointed as could be.

Not sure if you’re being sarcastic or not, but the actual project page is very useful: https://fishshell.com/

The OP is the equivalent of a changelog, which isn’t going to be terribly helpful to the uninitiated.

Thanks, this is exactly what is needed to get an idea what Fish is to begin with.

It is all too common for github pages to have no reference to more introductory material, and no obvious introductory material of their own.

Ah yes. The wisdom of the OP’s obscurity becomes clear now.
