4.1.0

✨ The 4.1.0 tour

A fleet you can run from one screen. CodeAlta 4.1 gives Fleet a home: an overview and tables that scale, machines that start at boot and sign in from your desk, and automations that chain and run without a model. It also brings side questions, notes on your project's pages, and a calmer workspace. Here is the tour of what is new since 4.0.0.

🛰️ The Fleet console

Settings > Fleet opens on an Overview: how many machines are online, what needs your attention, the server of each space, and what is left to set up. Machines, people, devices, policies and the audit log are now tables you can sort and filter. They show a large fleet a page at a time, and the audit log is read from the server by page and filter, however long it gets. More → (#369)

🔑 Machines that stay on and sign in from your desk

Tick Always on when you add a machine over SSH or create your server, and its node starts at boot: a Windows service, a LaunchDaemon on a Mac, or a lingering systemd unit on Linux. The page of a machine tells you whether it does. Sign in… on that page signs the machine in to Codex, GitHub Copilot, Claude Code (on Windows too), Mistral Vibe, ACP agents that take an API key, MCP servers and gh. You don't need a terminal or SSH: the machine keeps the token, and your computer only relays the code. Pairing two desktops now works both ways in one step. More → (#365, #366, #359)

💬 Side questions

Ask the model of a session about it while the session goes on, without adding the question to the conversation: click the speech bubbles beside the microphone, or type /ask. Every provider answers them, Claude Code, Codex CLI and ACP agents included, and earlier answers stay in a list. More → (#370)

🖍️ Notes on your project's pages

In the CodeAlta browser, click Annotate, mark the elements of a page of your project and write what should change. You can paste a mockup too. The notes reach the session with the source files where each element is written. More → (#355, #356)

⚡ Automations that chain

An automation can now start when a project is added, archived or removed, when another automation ends, or on an event from a source or a plugin. With Run without a model, a script does the work alone. Plugins can add triggers and scripts to the library of Code Mode. More → (#354)

📋 Your work, by day

Work items shows when each task and plan was created. They are grouped by Today, Yesterday, This week, Last week and by month, newest or oldest first. The Issues tab shows 50 items at a time, with Show 50 more up to 500, on GitHub, GitLab, Bitbucket and Azure DevOps. More →

📰 What's new, inside CodeAlta

The Release notes window reads the releases from GitHub. It tells you when a newer version is out, and shows what it brings once you update. More →

🎁 And also

• Windows that fit. Smaller and Larger in the title bar of every window, Settings included.
• Find on the phone. Search a session or a file from your phone; long activity headlines no longer get cut. (#374, #371)
• Model lists in order. Models sort by family and version. (#361)
• Project MCP servers. Servers of .alta/mcp.json find the files of the project, relative paths and variables included. (#368)
• Cleanups that count. Clearing the scratchpad and removing worktrees say how much space they free.
• Sessions on a node. Each session started on a machine gets a worktree of its own and the machine's sandbox, and its worktrees are removed when no session uses them.
• The little snags. Fixes cover "No model ready" while providers start, a middle click that pasted into the prompt, phones over Dev Tunnels, fleet machines that asked before every tool call, worktrees left behind by deleted child sessions, and the Search card of the welcome page. (#367, #357, #364, #358, #372, #373)

🙏 Thank you

To @kzu for side questions, model lists in order and the phone's headlines; @windischb for browser annotations, plugin requests across windows and worktree cleanup; and @xen2 for find on the phone and the prompt's right-click menu.

And to @emmanuelbretonbelz, @BenjaBobs, @dpen2000 and @TechInterMezzo for the requests and reports behind the Project trigger, the middle-click fix, fleet approvals, Dev Tunnels and "No model ready".
