Conn v0.8.3 (preview)

Conn v0.8.3

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

Validation: 246 Rust tests, 46 frontend tests, 78 release tests, production-App browser fixtures, the real Rust Harness collaboration flow and a real OpenSSH authentication/sharing regression passed locally. Interactive testing of this patch on macOS was not performed because the test Mac is offline; Linux/Windows native GUI acceptance and installed-app upgrade coverage also remain open. Release CI and signing checks are reported separately.

한국어: 로컬 Rust 246개·프런트엔드 46개·릴리스 78개 테스트, 실제 App 브라우저 검증·Rust Harness 협업 흐름·실제 OpenSSH 인증 및 공유 회귀 검증을 통과했습니다. 테스트 Mac이 꺼져 있어 이번 패치의 macOS 대화형 검증은 하지 않았습니다. Linux·Windows 네이티브 GUI 및 설치된 앱의 업그레이드 검증도 남아 있습니다.

• Connection approval stays actionable in private, empty, preparing and Settings views. Failed decisions remain retryable, and late snapshots cannot resurrect resolved requests.
• Sharing validates input, live participants, history resources and the selected revision before revoking external input. Failed transitions preserve the running shell and writer; stale selections require reloading.
• Centralize connection admission, cross-session control transitions, participation cleanup and typed UI state. Owner grants and hand-backs enforce one lease per connection; explicit take/release and process exit cancel pending work. Cards, keyboard and palette decisions share their request state.
• Add required browser collaboration regressions using the production App and real Rust Harness. Implementation and validation; native platform acceptance remains open.

한국어: 비공개 화면에서도 연결 승인을 처리하고, 공유 실패 시 기존 셸과 외부 입력 권한을 유지합니다. 연결·참여·제어권·UI 상태의 책임을 분리했으며, 오래된 공유 선택은 다시 확인하게 합니다. 구현·검증 결과에 플랫폼별 남은 검증을 구분했습니다.

• Snapshots no longer carry the constant imageUnavailable: true field, a remnant of the optional PNG snapshots removed in 0.8.0. Snapshots remain text only.
• Removed the native OpenAI command suggestions preview, its provider settings and the OS credential-store key storage. Themes and the extension registry stay. A key saved earlier remains in the OS credential store under dev.eggp.conn.model-provider until you delete it there.

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.
