Changelog
Newest first. Each minor release is a deliberate “floor” — functional and daily-driven before the next. Full history + downloads on GitHub Releases.
0.11.1 — “Paste the Picture”
Section titled “0.11.1 — “Paste the Picture””Native macOS support ships: a universal (Apple Silicon + Intel) build with darwin auto-update entries alongside the existing Windows updater. See Install & first run for the Gatekeeper first-run step (ad-hoc signed, not notarized).
- Paste screenshots into panes —
Ctrl+Vwith an image on the clipboard writes it to a temp PNG and pastes the (shell-translated) path into the pane, so agents can read the image natively.
0.11.0 — “The Thaw”
Section titled “0.11.0 — “The Thaw””Six fixes and quality-of-life improvements across the pane/terminal layer:
- All-shells PTY freeze fix — resolves a freeze that could affect any shell, not just one kind.
- Clickable terminal hyperlinks, plus a WebGL repaint fix.
- Respawn preserves the live working directory instead of resetting to the project root.
- Git Bash opens in the project directory.
- Per-project active-pane memory — Atrium remembers which pane was focused, per project.
- WSL2 pressure relief + disclosure — eases and surfaces the shared-VM memory-pressure behavior described below.
0.10.0 — “The Cockpit, Furnished” — 2026-06-14
Section titled “0.10.0 — “The Cockpit, Furnished” — 2026-06-14”The largest release since the cockpit foundation: a full next-era program plus a deep polish-and-fix pass, consolidating everything accumulated since 0.9.4.
- Worktree View — a pane-geometry lens: partition selector, agent/shell slots, tabbed panes, per-project view memory, empty-slot spawn, and entry points from the Sidebar and Switcher.
- Pro v1 bundle — focus-aware desktop notifications + OSC 9/777 passthrough, named workspaces
(save/materialize), Switcher action verbs, and per-worktree runtime vars (
$ATRIUM_PORT/$ATRIUM_WORKTREE) so two worktrees can run the same dev server on distinct ports. All Pro code is dead-code-eliminated from the Free build. - Theming — six preset themes (dark, light, high-contrast, nord, solarized-dark, sepia) with a glow-intensity control; status-orb semantics stay constant across every theme.
- Command palette — a
?shortcut cheatsheet overlay over a single data-first command/keybinding registry. - Pane power — pin a pane to the top of its group, scrollback search (
Ctrl+Shift+/), “Open lazygit here,” a per-pane Restart button. - Status legibility — the
StatusDotorb system across Sidebar, Dashboard, and Rail, with a status legend and hover descriptions. - Distribution/quality — copy a diff or commit-graph as shareable markdown, plus a no-telemetry pass.
0.9.4 — “Worktree Lifecycle”
Section titled “0.9.4 — “Worktree Lifecycle””Full worktree lifecycle management from the UI.
- Spawn any pane kind into a worktree — a
＋▾caret per worktree opens the full spawn menu scoped to that directory. - New/remove worktree dialogs — create a worktree with a new or existing branch; remove with a
two-gate destructive confirm (homed panes, git’s
--forcegate on dirty worktrees). - Prune orphaned worktrees — one-click
git worktree prunefrom Inventory, with a prunable-count badge. - Per-project Sidebar view memory — the Groups/Worktrees toggle persists and survives restart.
- ErrorBoundary — a top-level React error boundary so render crashes show a recoverable panel instead of a blank screen.
- Removed: the
.mcp.jsonauto-writer. Atrium no longer writes MCP discovery config when a Claude pane opens. The MCP server itself still ships in the binary — connecting it is now a manual, per-project opt-in. Auto-discovery will return as an explicit opt-in with the Pro edition; it will never be on by default.
0.9.0 — “Editions & Worktrees”
Section titled “0.9.0 — “Editions & Worktrees””A git-worktree lens for the Sidebar, plus the developer foundation for the Free/Pro editions. Windows/WSL2 build at the time — native macOS support shipped later, in 0.11.1.
- Worktrees view — a git-worktree organizing lens in the Sidebar: each worktree as a two-line row with a group-colored orb, empty worktrees as launch targets, drift detection, and move-to-worktree. Bare-clone and traditional layouts; graceful on non-git repos.
- Free/Pro edition seam (foundation) — a build-time
isPro()seam with free/pro build modes and a CI guard proving a free build excludes all Pro code (at the time, that included the MCP auto-discovery wiring — removed entirely in 0.9.4). Atrium stays free (organization); Pro (augmentation) is in active development as a paid, one-time-purchase edition. The standard build ships in 0.9.0; the genuine free/pro split lands ahead of 1.0, as part of Atrium’s commercial launch. - Privacy policy — provable no-telemetry, no backend the app depends on. See Privacy.
0.8.0 — “The Integration Layer”
Section titled “0.8.0 — “The Integration Layer””The agent-integration layer — visibility-in, never control-out.
- Atrium MCP server — a local stdio server each agent spawns itself, reaching Atrium over the
shared filesystem (works on default WSL2, no port/firewall/token). Read tools:
list_projects,list_panes,pane_status,read_pane_output(read a sibling pane’s logs),list_todos,read_scratchpad. Write-into-Atrium tools:add_todo,set_todo_status,append_scratchpad. No control verb — enforced by a test. See The Atrium MCP server. (The auto-discovery wiring this shipped with was later removed in 0.9.4 — connecting is manual.) - Live status snapshot — the cockpit publishes real per-pane status so the MCP surface reflects what’s actually running.
- Context-window usage % on Claude panes (read from Claude’s own statusline).
- Agent-written TODOs appear live in the dock.
- App zoom — Ctrl
+/−/0, persisted. - First-class agent Providers — a capability registry per agent.
0.7.0 — “The Cockpit Foundation”
Section titled “0.7.0 — “The Cockpit Foundation””Dashboard with cross-project live status; read-only git diff + commit lane-graph; script auto-detection;
configurable editor (VS Code / Cursor / Zed / Windsurf / custom); per-project scratchpad + TODOs dock;
project.toml import/export; and polish (non-selectable chrome, right-click-to-paste).
The calm single-window organizer: projects → groups → panes with liveness, activity, attention, per-pane working directory (worktree scoping), session restoration, agent permissions, and read-only git branch context.
Earlier
Section titled “Earlier”0.1.0–0.5.0 established the Tauri + xterm.js foundation, cross-platform builds, and self-update. See GitHub Releases for details.
