The Rust port ships the same +user-facing `cua-driver` binary for macOS and Windows, plus Linux pre-release +artifacts for early testing. All versions are currently published as GitHub +**prereleases** under the `cua-driver-rs-v*` tag prefix (distinct from the Swift +driver's `cua-driver-v*` tags so their artifacts don't collide). + +The canonical, always-current source is the +[GitHub releases page](https://github.com/trycua/cua/releases). Each GitHub +release body is auto-generated per release from the commits touching +`libs/cua-driver/rust`, including SHA256 checksums and install instructions. + +## 0.5.1 (2026-06-01) + +- **Install home unified on `~/.cua-driver` + collision fix.** The release + installer (`install.sh` → `_install-rust.sh`) was still defaulting its package + home to the legacy `~/.cua-driver-rs`, while the local installer + (`install-local.sh`) and the runtime already used `~/.cua-driver` (renamed in + v0.2.16). That mismatch meant a machine could end up with two homes and two + conflicting installs. The release installer now defaults to `~/.cua-driver` + (still honoring the `CUA_DRIVER_RS_HOME` override), and on every install it (a) + cleans up a prior `install-local` dev build under the shared home — stops the + daemon, removes the `*-local-*` release dirs and the local signing-identity + marker — and (b) sweeps a stale `~/.cua-driver-rs` left by an older release. + Both steps are best-effort, idempotent, and conservative (marker-gated; they + never touch a real release dir, the `current` symlink, or unrelated user + state). TCC grants are preserved — the `/Applications/CuaDriver.app` bundle is + replaced in place, not `tccutil reset`. The Windows installer (`install.ps1`) + already used `~/.cua-driver` and migrated the legacy home, so it is unchanged. + +## 0.5.0 (2026-06-01) + +- **Windows: per-session agent cursors** — the per-session cursor model (macOS + #1779) is ported to Windows, so concurrent sessions are tracked per-session on + Windows too (#1801). +- **Streamable-HTTP MCP transport (parallel multi-agent).** Over stdio, one + `cua-driver mcp` process is a single pipe, so a client's tool calls — including + multiple subagents — serialize. The daemon itself is concurrent. Set + `CUA_DRIVER_RS_MCP_HTTP_PORT=` and the daemon also serves MCP over HTTP + (`POST http://127.0.0.1:/mcp`, loopback only), so each agent opens its + **own** connection and they run truly in parallel — measured 3.6× on 10 + concurrent calls. Per-connection ordering keeps a single agent's sequence + correct; the per-`(pid, window_id)` cache + per-session cursor make concurrent + cross-connection actions safe. `move_cursor` is now `readOnlyHint:true` so MCP + clients also parallelize cursor moves on stdio (mutating tools stay serialized + on purpose) (#1799). +- **Breaking — session identity is now caller-declared.** A "session" (which + owns the agent cursor + per-session state) used to be minted per MCP + connection, so it couldn't be set from the CLI and couldn't span a run that + touches multiple apps. It's now an explicit identity you declare: pass a + `session` id (or call the new `start_session`/`end_session` tools), and the + same id drives the same cursor over MCP, the CLI, or the raw socket, following + the run across any apps/windows. **The cursor is now opt-in:** a run shows a + cursor only when it declares a `session` — anonymous calls execute without one. + Sessions are reclaimed by `end_session` or an idle-TTL (default 300s, override + `CUA_DRIVER_RS_SESSION_IDLE_TTL_SECS`) instead of connection-EOF. Per-session + config + recording keep their existing connection-scoped cleanup as a fallback + when no `session` is declared. Update agents to `start_session` at the start of + a run (the bundled skill + MCP instructions now say so). +- macOS: fix a daemon crash (`EXC_BREAKPOINT` in `AXUIElementCopyActionNames`) + when two sessions drive the same window concurrently. Element actions + (`click`, `type_text`, `set_value`, …) read the target `AXUIElementRef` out + of the per-`(pid, window_id)` cache, but a concurrent `get_window_state` + could replace that cache entry and `CFRelease` the element to zero while the + action was still using it — a use-after-free. The cache now hands out a + retained guard (`CFRetain` under the cache lock, `CFRelease` on drop), so an + in-flight action keeps the element alive across a concurrent refresh. +- macOS (local dev install only): `install-local.sh` now clears a stale TCC + grant left over from a previous signing identity. If you first granted + Accessibility / Screen Recording while the bundle was ad-hoc signed, that + grant was pinned to the per-build `cdhash` and silently stopped matching on + the next rebuild — the daemon read `NOT granted` while System Settings still + showed CuaDriver toggled ON, a dead end re-toggling couldn't fix. The + installer records the signing identity and, when it changes, runs + `tccutil reset` so the next grant re-pins cleanly to the stable self-signed + certificate (after which grants survive all future rebuilds). Release builds + are unaffected — they're CI-signed with a stable identity (#1792 follow-up). + +## 0.4.3 (2026-05-31) + +- macOS: the agent-cursor overlay now actually renders in the `serve` daemon. + It was only wired into the in-process `mcp` path, so in the daemon-proxy + setup (the default) every cursor command was a silent no-op and the agent + cursor never appeared (#1790). +- macOS: `cua-driver permissions grant` no longer spams the TCC prompt — it + raises a single dialog and then polls silently, and the gate honours its + deadline instead of re-prompting (and restarting the daemon) on every + ~25s re-exec (#1791). +- Dev: `install-local` now signs the bundle with a stable self-signed + identity, so TCC grants (Accessibility / Screen Recording) survive rebuilds + instead of resetting on every install (#1792). + +## 0.4.2 (2026-05-31) + +- macOS: guard the SkyLight auth-message selector on macOS 14 Sonoma so the + driver no longer crashes on launch (#1782, #1503). +- macOS: enable Chromium/Electron accessibility trees via `AXManualAccessibility`, + so `get_window_state` can see their window content (#1756). + +## 0.4.1 (2026-05-31) + +- macOS: per-session agent cursors, so concurrent sessions each get their own + visual agent cursor (#1779). +- macOS: ship `AppIcon.icns` in the bundle so `CuaDriver.app` no longer shows a + blank icon (#1780, #1496). +- macOS: guard AppKit initialization so `mcp` runs headless instead of + SIGABRT-ing (#1781, #1724). + +## 0.4.0 (2026-05-31) + +- Daemon session-identity model: the daemon now owns and cleans up + session-scoped recording and config, tying that state to the session that + created it (#1776). + +## 0.3.6 (2026-05-30) + +- macOS: fix permissions status so it reports the driver's real TCC grants (via + the daemon) instead of the calling terminal's — it no longer claims granted + when only the caller holds the grant (#1774). + +## 0.3.5 (2026-05-30) + +- macOS: bind the `serve` socket before the permissions gate, so clients can + connect even while permissions are still being resolved (#1761, #1773). + +## 0.3.4 (2026-05-30) + +- Maintenance release (no path-specific changes). + +## 0.3.3 (2026-05-30) + +- Maintenance release (no path-specific changes). + +## 0.3.2 (2026-05-27) + +- Add a `check-update` CLI verb and a `check_for_update` MCP tool so clients can + detect when a newer driver is available (#1734). + +## 0.3.1 (2026-05-27) + +- First release in the 0.3.x line, which began the macOS TCC / permissions + hardening series. + +## 0.2.x (2026-05-17 – 2026-05-21) + +- Pre-release iteration on the Rust port across versions 0.2.0–0.2.18, + including cross-platform build and packaging work for the macOS, Windows, and + Linux pre-release artifacts. + +## 0.1.x (2026-05-14) + +- Initial `cua-driver-rs` pre-releases.

On the daemon-proxy path every `cua-driver mcp` client mints a session identity, and that identity is the cursor key when the caller passes no explicit `cursor_id` — so two concurrent sessions each drive their own overlay cursor (distinct auto-assigned colour) drawn simultaneously, instead of clobbering one shared cursor last-writer-wins. The key is resolved with the precedence **explicit `cursor_id` > session identity > `"default"`**: an explicit `cursor_id` stays an orthogonal, user-facing handle, so a wrapper can deliberately share or override a cursor across sessions by passing the same `cursor_id`. When a session ends (`session_end`), that session's cursor is removed from the overlay automatically — including on **ungraceful proxy death** (`kill -9`, crash), because the daemon detects the proxy's control-connection EOF and fires `session_end` without any cooperation from the dying proxy. A late, in-flight cursor command that arrives after removal cannot resurrect the cursor (a render-side tombstone keyed on the session id). The anonymous / one-shot `cua-driver call` path (no session identity, no `cursor_id`) maps to the seeded `"default"` cursor, which is never removed — backward compatible. (Windows/Linux keep the single shared cursor today.) +**Sessions and per-session agent cursors (macOS).** A **session** is a +caller-declared identity for one agent run — not a property of the MCP +connection. Declare it with `start_session` (or just pass a `session` id on your +actions); the same id drives the same agent cursor, per-session config, and +recording over MCP, the CLI, or the raw socket, and follows the run across any +number of apps/windows. The cursor's colour is auto-derived from the id, so +concurrent runs are visually distinct and drawn simultaneously. **The cursor is +opt-in:** a run shows a cursor only when it declares a `session` — anonymous +calls (no `session`) execute without one. `cursor_id` is a legacy alias for +`session`.

For +concurrent runs/subagents, give each its own `session` (and pass +`creates_new_application_instance:true` to `launch_app` so they don't share a +window). Per-session config + recording fall back to connection-scoped cleanup +when no `session` is declared. (Windows/Linux have no overlay cursor today; the +session identity still scopes their per-session config + recording.) + +### start_session + +Declare a session — a named, color-coded identity for the current agent run. Pass a stable `session` id; the agent cursor, per-session config, and recording all key on it, and it follows the run across apps/windows. The cursor appears on the session's first action.

For a clearly *gliding* cursor in a demo, issue a pixel `click({pid,x,y})` or a `move_agent_cursor` first to put the cursor on-screen; subsequent AX clicks then glide normally. **Arguments:** diff --git a/docs/content/docs/cua-driver/reference/meta.json b/docs/content/docs/cua-driver/reference/meta.json index 6a86740522..e96d110716 100644 --- a/docs/content/docs/cua-driver/reference/meta.json +++ b/docs/content/docs/cua-driver/reference/meta.json @@ -2,5 +2,5 @@ "title": "Reference", "description": "CLI and MCP reference documentation", "icon": "FileText", - "pages": ["cli-reference", "mcp-tools", "limits"] + "pages": ["cli-reference", "mcp-tools", "limits", "changelog"] } diff --git a/flake.nix b/flake.nix index ea800a6810..a2b9ac9204 100644 --- a/flake.nix +++ b/flake.nix @@ -79,7 +79,34 @@ services.cua-driver.package = cuaDriverPackage; }; }; - }; + } + // pkgs.lib.optionalAttrs (system == "x86_64-linux") ( + # Background GUI input coverage — one independent matrix job per + # app, proving focus-free typing into real toolkit/browser windows. + pkgs.lib.listToAttrs ( + map ( + app: + pkgs.lib.nameValuePair "cua-driver-linux-background-gui-${app}" ( + import ./nix/cua-driver/tests/linux-background-gui.nix { + inherit pkgs app; + inherit (pkgs) lib; + cuaDriverModule = { + imports = [ ./nix/cua-driver/module.nix ]; + services.cua-driver.package = cuaDriverPackage; + }; + } + ) + # "firefox" temporarily disabled: it does not surface its + # window within the launch timeout under the emulated CI VM + # (no KVM), so the job times out before any AT-SPI subtest + # runs.
