Athas 0.13.0 brings the editor into a more unified, flexible workbench. Settings now open as a workbench tab, main tabs are draggable, terminal panes integrate with the main surface, the Activity sidebar resizes live, and shared chrome is more consistent across editor, project, and tool views.
Workspace and project workflows are faster and more dependable. This release centralizes local and remote workspace lifecycle management, improves session restoration and file-provider behavior, adds project management and remote connection entry points to the switcher, and reduces resource use for inactive workspaces.
AI, agent, and review tools are substantially more capable. Agent integrations have been modernized with structured tool results, reliable session lifecycle handling, editor-selection context, and hunk-based Intelligence review. Built-in model catalogs now include Claude Fable 5.1 and Qwen 3.8 Flash, use current Mistral IDs, and default Anthropic chat to Claude Sonnet 5 while migrating saved selections.
Source Control, debugging, and navigation received focused upgrades. Review is now part of Source Control, repository and branch selection are unified, commit controls are clearer, debugger actions and breakpoints are easier to reach, Outline remains available for editor tabs, and file-tree folder arrows can be configured without compact folders being forced on.
Extensions and language tooling cover more real-world workflows. Extension views are responsive and more strongly typed, installs can be interrupted, Vercel and v0 integrations are externalized, database extension delivery is improved, Java workflows are complete, and managed runtime contracts are more consistent.
Platform polish and reliability extend across macOS, Linux, Windows, and the terminal. The release improves native macOS workspace integration, restores Linux file dialogs and keyboard support, fixes Vim ex commands and terminal tab shortcuts, stabilizes remote connections, and updates audited Rust networking, XML, and concurrency dependencies.
