Kestrel v0.9.1

What's new in 0.9.1

Linux AppImage starts again. 0.9.0 crashed on start on systems with an older glibc (for example Ubuntu 24.04: "Failed to load native module: pty.node"). The AppImage is now built on Ubuntu 22.04 and runs on that and newer, and the build checks this from now on.

Up to four agents at once. Each agent gets its own tab in the agent panel, with its own permission questions. A file with a held change is locked for the other agents, and restoring a checkpoint while agents are working asks first.

Kestrel v0.9.0

What's new in 0.9.0

Language servers. Completion, hover, go to definition and a Problems list from real language servers – TypeScript (downloaded via npx on first use), Pyright, rust-analyzer, gopls or your own. Agents can read the current problems through the get_diagnostics tool.

Git panel. Stage, unstage and discard per file or section, commit with Ctrl+Enter, switch or create branches, fetch, pull and push, and see diffs side by side. Changed files are marked in the file tree; the status bar shows the branch.

Restricted mode for new projects. Language servers and Git can run code from a project (tsserver plugins, hooks, filters). They only do so after you trust the project in a native dialog; until then Git only reads.

Your layout. Any command as a toolbar button (Pull and Push are there by default), sidebar and agent panel on either side, hide what you don't use, save layouts – or describe the IDE you want and let your chat model propose it, with a preview and Undo.

Fixes. Local Ollama models in the chat no longer claim to be a company's assistant; the Linux AppImage builds again; more reliable tests on CI.
