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 Speakeasy?
Speakeasy stopped inventorying MCP servers and started adjudicating them.
Speakeasy ships near-daily platform releases with unusually legible notes — each headline states what changed for a user, not a version number. The current one turns the Shadow MCP page into a single review surface where every server carries an approval state and an automatically gathered evidence dossier: publisher, requested scopes, declared capabilities, maintenance signals, and whether internal teams already talk to it. Decisions enforce on record. Around it, the assistant surfaces have been consolidating: one detail panel for configuration and observation, exact session totals, and canonical identities folding a person's work and personal AI accounts together.

fish shell
2.5DEVOPS
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.
Speakeasy
10.0DEVOPS
Speakeasy stopped inventorying MCP servers and started adjudicating them.
◆ Current state
Speakeasy ships near-daily platform releases with unusually legible notes — each headline states what changed for a user, not a version number. The current one turns the Shadow MCP page into a single review surface where every server carries an approval state and an automatically gathered evidence dossier: publisher, requested scopes, declared capabilities, maintenance signals, and whether internal teams already talk to it. Decisions enforce on record. Around it, the assistant surfaces have been consolidating: one detail panel for configuration and observation, exact session totals, and canonical identities folding a person's work and personal AI accounts together.
◆ Where it's heading
The arc runs observe, then intercept, now adjudicate. Earlier releases catalogued spend and inventoried shadow MCP servers; the LiteLLM integration moved enforcement to the proxy so a violating prompt dies before inference; this release supplies the judgment layer, doing the research an approver would otherwise do by hand. The supporting work points the same way — prompt-injection scanning of captured skill manifests, risk policies that pause instead of being deleted, identity resolution that reports a whole person rather than an account. Each is a piece a control plane needs before its verdicts can be trusted.
◆ Prediction
Expect approval state to start gating traffic rather than only recording a decision, and the evidence dossier to extend from MCP servers to the skills and assistants already being captured. The rollout flag on the approval workflow suggests general availability is the next step rather than new capability.
