LINE CLI v0.5.0

What's Changed

• Add message-history pagination with messages --page --json and continuation cursors
• Add bounded lookup of older messages for replies, downloads, reactions, and unsends
• Add --details --json for structured chat and message content, including locations, attachments, stickers, contacts, and mentions
• Add optional sender-name lookup with --resolve-names
• Add members to list group members and invitees
• Add send --mentions with validated UTF-16 spans for text, stdin, and replies
• Add --timeout across core commands and improve cancellation and terminal restoration
• Add global --error-format=json with structured errors, mutation outcomes, and sanitized request diagnostics
• Add messages --diagnostics --json to inspect history IDs and counts before decryption
• Preserve confirmed mutation outcomes when output fails and report partial failures without automatically replaying actions
• Prefer Letter Sealing and automatically use HTTPS/TLS when LINE explicitly reports no E2EE support. Add --require-e2ee to block non-E2EE sends; LINE can read non-E2EE content. See LINE’s Encryption Report 2025
• Add JPEG/PNG image preparation and capability-checked non-E2EE sending. Encrypted native-image sending remains disabled, and live image delivery remains unverified
• Fix group encryption to honor LINE's negotiated encryption version
• Improve chat search and profile lookup when some profiles are unavailable
• Keep encrypted-file keys and filenames inside the authenticated Letter Sealing payload. Live encrypted-file interoperability remains unverified
• Reject authenticated-request redirects and limit response sizes and SSE event accumulation
• Require Go 1.27.2 for source builds and add source and release-binary vulnerability scans
• Consolidate JSON, session, security, and development references, and bundle the complete documentation in every release archive

Full Changelog: v0.4.0...v0.5.0

Full Changelog: v0.3.1...v0.4.0

LINE CLI v0.3.1

What's Changed

• Reliable V3 token refresh at the normal approximately 168-hour (7-day) access-token boundary, using server timing metadata and durable access/refresh-token rotation
• Bounded exponential backoff and jitter using LINE's refresh retry policy, with cancellation support
• Improved authentication error detection and safe read recovery, while preserving single-shot sends, reactions, unsends, and uploads
• Resilient line watch reconnection after token refresh, with protection against stale clients invalidating newer credentials
• Expanded regression coverage for proactive refresh, token rotation, concurrent recovery, forced logout, and simulated restarts across the seven-day refresh boundary
• Documentation updates across English, Thai, Japanese, and Traditional Chinese, plus a detailed token/session audit and LINEJS/Beeper comparison

LINE CLI v0.1.0

The first standalone LINE CLI release: use your personal LINE account from a terminal, with guided prompts for everyday use and JSON output for scripts.

What's included

• line login, whoami, contacts, chats, messages, send, and logout.
• Searchable chat selection, readable conversation history, and recipient names instead of copying IDs.
• Letter Sealing encrypted text and generic file attachments up to 20 MiB.
• Replies, six standard reactions, reaction removal, file downloads, and unsend.
• Live events with line watch, saved resume position, and NDJSON output.
• Native credential protection: macOS Keychain, Linux Secret Service, and Windows DPAPI.
• A standalone CLI with the legacy Matrix/Beeper bridge removed; upstream MIT attribution retained.

Download and install

Choose the archive matching your computer:

Computer	Archive
macOS — Apple Silicon	line-darwin-arm64.tar.gz
macOS — Intel	line-darwin-amd64.tar.gz
Linux — Intel/AMD 64-bit	line-linux-amd64.tar.gz
Linux — ARM64	line-linux-arm64.tar.gz

Extract into a new directory, verify the included SHA256SUMS, and place line or line.exe on your PATH. SHA256SUMS.txt attached to this release also contains checksums for the six archives. Each archive includes the README, CLI reference, and MIT license. Go is not required to run these binaries.

On macOS, verify the extracted binary with shasum -a 256 -c SHA256SUMS; on Linux, use sha256sum -c SHA256SUMS. On Windows, compare Get-FileHash .\line.exe -Algorithm SHA256 with the included checksum.

Start with:

line version
line login
line chats
line messages
line send

See the installation and usage guide and complete CLI reference.

Validation

Tagged CI passed on Linux, macOS, and Windows, including native Linux Secret Service and Windows DPAPI checks. All six release builds passed. The macOS Apple Silicon release binary passed local version/help startup checks without accessing a LINE account.

Requirements and current limits

• Login needs an email/password configured in LINE and phone approval. This client uses a Chrome-style session and may replace another LINE Chrome extension session.
• Linux needs secret-tool and an unlocked Secret Service keyring in the current D-Bus session. There is no plaintext credential fallback.
• Binaries are unsigned and not notarized. macOS may require approval in Privacy & Security. Keep the executable at a stable path for Keychain access.
• Recent message history is limited to 100 messages per read. File uploads are generic files, not specialized photo/video/audio messages.
• Only one saved account is supported. Reading does not mark messages read; logout removes the local saved session.
• Fresh group-key registration, some live token-refresh scenarios, and live watch message-event delivery still have validation gaps. No send is automatically retried after an uncertain result.

This is an independent client derived from beeper/line, not an official LINE product.
