What’s new
in Mars.

A new look, and one panel for the work

The app is redrawn, and Git, files, the browser, the terminal and Metrics now sit in one panel beside the chat.

A new look

The app is redrawn in two themes, Regolith Night and Regolith Day, with a new font, Onest.

The terminal client, redrawn

The CLI gets the app’s new themes and a clearer layout, and scripts can review changes and see how each run ended.

01New

New look in the terminal

Regolith Night, Regolith Day, or Terminal with your terminal’s own colours. Lines stay under 90 characters, and your messages sit on the right.

Mars remembers your project and uses fewer tokens

The first part of 0.2.0. Long chats no longer start over, Mars keeps notes about the project between sessions, and runs get through provider hiccups.

Send messages while the agent works

Your messages reach a running agent right away, approvals take one line, and model details now come from the providers themselves.

A redrawn app, with plans and reviews as cards

The app got a new dark design, plans and reviews became cards you act on, and what a session costs shows under the input box.

Twenty-three languages and a stricter agent

The interface is translated, the agent tests its work before it says it is done, and 57 bugs found in an audit are fixed.

More reliable summaries and clearer status

Long chats are summarised more reliably, and cost and status are easier to see.

A tidier workspace

Files, Git and session activity look and behave the same everywhere in the app.

The agent checks its work before handing it over

Agents look at the workflows they have before starting and review their changes before they hand them over.

Skills and checks at the start of a run

The same agent core as the desktop: it reads your workflows first and checks its changes before it hands them over.

Project checks in one place

Run formatting, lint, types, tests and builds as one job and read its report.

Project checks from the terminal

The checks added in this version are part of the shared core, so they work in the CLI too.

Many files at once, and Git in the app

Agents can change several files in one step, and Git lives inside the workspace.

Many files at once

New file tools and steadier messages during a run, shared with the desktop.

Media in messages, a better model picker, signed updates

Desktop and CLI share one agent core. Install this build once from Downloads to get the new updater.

A redesigned terminal client

The CLI is rebuilt on a shared design layer: one reading column, no frames, and the same agent core as the desktop.

One reading column

Status marks sit in a narrow column beside the text, times and counts on the right, and no boxes.

Clearer agent activity

See what each agent did and which files a run changed.

A workspace for agent teams

Follow a team of agents, the messages between them and the context they keep.

A compact sidebar and a clearer skill library

Skill packs in the CLI

Skill packs and plugin changes from this version work in the CLI as well.

Skills and plugins arrive

Skills and plugins in the CLI

The new skills catalogue and plugins are shared by the desktop and the CLI.
