The alternatives below are ranked the same way, so you're comparing real release momentum, not marketing claims.
About fish shell
Four minor versions in five months, and the shell's remaining work is almost all interaction detail.
fish is deep into the 4.x Rust-era grind: 4.4.0 through 4.8.1 land in roughly five months, each carrying 60-234 commits from a steadily widening contributor base with new committers in every release. The changes are overwhelmingly interactive — keybindings, completion pager behavior, prompt handling, color variables. Each minor release is followed within days or weeks by a patch cleaning up its own regressions.
