fish shell

Fish Shell 4 is here, completely rewritten in Rust with improved key bindings, self-installable builds, better history control, and more.

Two years, 57k lines of C++, now 75k lines of Rust. Fish Shell 4.0 beta has been entirely rewritten in the Rust programming language.

Fish Shell 3.7.0 improves history pager, performance, and scripting. Future 4.x releases will transition Fish internals to Rust.
