What is 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.

What is Alacritty?

Alacritty ships twice a year and spends it on config syntax, Wayland and IME.

The feed interleaves two things: application releases and tags for the alacritty_terminal library crate, the latter carrying no release notes at all. The one substantive release in this window, 0.17.0, adds mouse wheel bindings, TOML 1.1 syntax support, and window.resize_increments on Wayland, alongside IME behavior changes on X11 and touch input and a new escapes manpage. Before it, 0.16.1 was a single crash fix for GPUs with partial robustness support.

fish shell vs Alacritty: editorial side-by-side

F2.5

Four minor versions in five months, and the shell's remaining work is almost all interaction detail.

◆ Current state

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.

◆ Where it's heading

Two threads run underneath the interaction polish. One is shedding legacy C-era dependencies: terminfo and ncurses are gone for good, and 4.8.0 moves Rust-side translation off GNU gettext onto Fluent with purpose-built tooling. The other is fitting into a modern terminal environment rather than working around old ones — OSC 133 prompt marking, systemd run0's prompt variables, emoji width defaulting to 2. The project is trading compatibility with terminals nobody runs for fidelity in the ones people actually use.

◆ Prediction

Expect the gettext-to-Fluent migration to extend from Rust source into fish script messages, since 4.8.0 flags script translations as the remaining holdout, and expect the release-then-patch rhythm to continue given every minor in this window needed one.

Alacritty
DEVOPS
0.0

Alacritty ships twice a year and spends it on config syntax, Wayland and IME.

◆ Current state

The feed interleaves two things: application releases and tags for the alacritty_terminal library crate, the latter carrying no release notes at all. The one substantive release in this window, 0.17.0, adds mouse wheel bindings, TOML 1.1 syntax support, and window.resize_increments on Wayland, alongside IME behavior changes on X11 and touch input and a new escapes manpage. Before it, 0.16.1 was a single crash fix for GPUs with partial robustness support.

◆ Where it's heading

This is a mature terminal emulator on a deliberately slow cadence, and the work concentrates where the platform underneath keeps moving: Wayland window sizing, input method handling across X11 and touch, and GPU driver edge cases. Configuration is the other thread, with TOML syntax support advancing and more of the terminal's behavior becoming bindable. Every application release ships a release candidate carrying an identical change list first.

◆ Prediction

Recent additions are all bindings and configuration surface rather than terminal features, and the library crate is versioned separately on its own cadence; more of the same incremental configurability is what these entries support, on a timeline measured in months.
