Conn v0.8.5 (preview)

Conn v0.8.5

Preview / prerelease. Conn gives a human and an agent one shared shell with
visible control handoff, command approval, and a combined collaboration timeline.
These binaries are built by CI; a green build is not a claim of full manual
validation on every operating system.

Installers include the app and its Conn CLI sidecar; Rust and Node.js are not
required to use these binaries. Windows preview installers are unsigned, so a
SmartScreen or unknown-publisher prompt may appear. Native CLI startup is checked
in CI; full interactive GUI installation/collaboration checks remain pending.

New in this release

• Restore policy-based Autopilot in POSIX SSH: ordinary commands run, risky commands request approval, and deny rules remain blocked. Remote paths are never inspected as host files.
• Make Allow this session work for SSH confirm rules and publish the allowance immediately. Programs requiring individual review explain that requirement instead of showing an inert button. The control indicator explains the selected collaboration mode.
• Stop resizing the underlying terminal when opening the modal settings sheet. The obsolete side-panel width animation repeatedly resized SSH line editors and corrupted long input/cursor placement.
• Keep approval actions visible while long command details scroll inside the common decision card.

한국어: POSIX SSH의 Autopilot에서 일반 명령은 자동 실행하고 위험 명령은 승인을 받도록 수정했습니다. 세션 허용은 해당 확인 규칙에 적용하고 즉시 표시하며, 명령별 검토가 필요한 경우에는 이유를 안내합니다. 모달 설정 뒤에서 남아 있던 터미널 너비 변경을 제거해 재현된 긴 입력·커서 깨짐을 수정했습니다. 긴 명령의 승인 내용은 카드 안에서 스크롤하고 승인 버튼은 계속 표시합니다.

Validation: 258 Rust tests, 48 frontend tests, 85 core/xterm comparisons, real SSH browser regressions and the 12-stage collaboration harness passed. On Apple Silicon macOS 27.0, the same product code was also exercised in an ad-hoc signed native debug app with real WebKit, Tauri IPC and loopback SSH: long input, cursor editing, approval/session allowances, takeover and original-shell return passed. Release artifact signing/notarization and installation checks are separate.

Remaining coverage: physical-keyboard Korean IME composition and the user's exact SSH setup remain unverified. WebKit emitted ResizeObserver warnings without a persistent mismatch in the checked steps. Other macOS versions, Windows interactive GUI and full installed-app upgrades remain open. Validation report.

한국어: Rust 258개·프런트엔드 48개·화면 비교 85회·실제 SSH 브라우저 회귀·협업 하네스 12단계를 통과했습니다. Apple Silicon macOS 27.0의 실제 WebKit·Tauri 디버그 앱과 SSH에서 긴 입력·커서 편집·승인·세션 허용·제어권 회수·원래 셸 복귀도 확인했습니다. 배포 파일 서명·공증과 설치 검사는 별도입니다. 실제 키보드 한글 IME 조합과 사용자의 정확한 SSH 환경은 미검증이며, ResizeObserver 경고가 관찰됐습니다. 다른 macOS 버전, Windows 대화형 UI와 설치된 앱의 전체 업그레이드 검증은 남아 있습니다. 검증 보고서.

Updating

Update the app and its CLI/MCP adapter together, then restart your MCP clients.
Existing files, profiles and saved activity remain; running shell sessions close
during app restart and are not migrated.

Installations from v0.6.0 on can discover this preview through the signed updater. Older
clients need a manual install. Updates support Apple Silicon macOS, Windows x64
and Linux AppImage; Debian packages use package-manager/manual updates. Installation
and restart remain your choice. Full installed-app upgrade coverage on every target
is not claimed by artifact signature checks.

한국어: 앱·CLI를 함께 업데이트하고 MCP 클라이언트를 재시작하세요. 파일·설정·저장 기록은
유지하며 실행 중인 셸은 앱 재시작 시 종료됩니다. v0.6.0 이후 설치본은 서명 업데이트를 사용할
수 있고 그보다 이전 버전은 직접 설치하세요.

Native validation and remaining coverage

Validation coverage is recorded per version in the changelog and linked reports.
CI builds, scripting-dictionary checks, signing and notarization are separate from
interactive testing of an installed app. Previous development-app results do not
establish that every native interaction works in this build. Windows interactive
GUI and full installed-app upgrades remain unverified.

AppleScript is disabled by default. Enable it for selected local profiles in Settings
and consult the automation guide.

Getting started

• English guide
• 한국어 사용법
• What changed

For a separate MCP connector, download the matching CLI for
Apple Silicon,
Windows x64 or
Linux x64.
Linux x64 assets are built on Ubuntu 24.04 and target
Ubuntu 24.04/26.04; runtime coverage of these exact assets is separate from CI.
Windows targets x64 and is intentionally unsigned for this preview; a certificate
is not a release prerequisite. SmartScreen or unknown-publisher prompts may appear.
macOS apps, their embedded CLI sidecars, and standalone CLIs are Developer ID
signed with hardened runtime and secure timestamps. Apple notarization is
Accepted for the final DMGs and standalone CLI submissions; app and DMG tickets
are stapled and verified. Apple does not support stapling a standalone CLI or
its archive, so its notarization ticket is retrieved online when needed.
The Apple Silicon -signing.json asset records native runner checks and final asset hashes;
it is evidence of this build, not an independent cryptographic attestation.
Intel Mac packages are paused for new releases; previously published assets remain available.
Native interactive installation and collaboration coverage remains limited for this preview.
See the platform policy.
Follow the installation guide for platform trust prompts; never disable system
protection globally.

Verify the download

Download SHA256SUMS with your selected asset. On Linux, run
sha256sum --ignore-missing -c SHA256SUMS from that directory. On macOS, compare
shasum -a 256 <asset> to the matching line; on Windows use
Get-FileHash <asset> -Algorithm SHA256. SHA-256 detects download corruption;
the checksum file is not a code-signing signature.

Before giving an agent control

Commands use your account's permissions. Conn's policy and approval UI are not
an operating-system sandbox. An “executed” record means input reached the shell,
not that the command completed successfully. Start with a disposable project.
Read the security model and
report security issues privately.

한국어: AppleScript는 기본적으로 꺼져 있습니다. 버전별 검증 범위는 변경 기록과 연결된 보고서를 확인하세요. CI 빌드·스크립팅 사전·서명·공증 검증은 설치된 앱의 대화형 검증과 별개이며, 이전 개발 앱의 결과가 이번 배포판의 모든 동작을 보장하지 않습니다.
이 릴리스는 프리뷰입니다. 명령은 사용자 계정 권한으로 실행되며, 승인 기능은
운영체제 샌드박스가 아닙니다. 실행 기록은 입력 전달을 뜻하며 명령의 성공을 보장하지
않습니다. macOS 앱·내장 CLI·별도 CLI는 Developer ID로 서명하며 hardened runtime과
보안 타임스탬프를 검증합니다. DMG와 별도 CLI의 Apple 공증이 승인되었고 앱·DMG에는
티켓을 첨부했습니다. 별도 CLI와 아카이브에는 티켓을 첨부할 수 없어 필요 시 온라인으로
조회합니다. Apple Silicon 서명 보고서는 해당 빌드의 검증 기록이며 독립적인 암호학적 증명은 아닙니다.
새 릴리스의 Intel Mac 배포는 중단하며 기존 공개 파일은 유지합니다.
Windows 프리뷰는 무서명으로 배포하며 인증서가 필수 조건은 아닙니다. Linux는
Ubuntu 24.04 빌드를 24.04·26.04 대상으로 제공합니다. CI에서 각 운영체제의 별도 CLI
시작을 확인하며, 네이티브 GUI 설치·협업의 전체 대화형 검증은 아직 완료되지 않았습니다.
