• Audio messages decryption — handle OID extraction from decrypted audio messages
• Video reliability — media downloads use context for better error handling
• Reactions disabled — outgoing reactions disabled (LINE doesn't support them)

1.1.0

🔄️ Changelog (1.0.2 → 1.1.0)

✨New Features

• Letter Sealing OFF (LSOFF) support — login and messaging for accounts without E2EE enabled, with automatic plain text fallback
• Audio messages — send and receive voice notes / audio files (E2EE and plain)
• Video & file receive — plain media receive with correct OBS routing
• Location messages — receive and display LINE location shares with Google Maps links
• Contact sharing — LINE contacts shown as notices; device contacts bridged as vCard files
• Call notifications — voice/video call events displayed with duration or missed status
• Message unsending — unsend messages from Matrix (with LINE's 24h limit and proper error)
• Link previews — text messages include URL previews via LINE's GetPageInfo
• Custom display names — 1:1 chats use the contact's custom display name
• Media flow detection — check determineMediaMessageFlow before choosing E2EE vs plain upload path
• File upload ZIP fallback — files rejected by LINE are automatically retried wrapped in a ZIP archive (matching Chrome Extension behavior)
• Additional audio/video MIME types — files sent as MsgFile with audio/video/image MIME are remapped to the correct LINE content type

🐛 Bug Fixes

• First-login E2EE key extraction — fixed crash when fetching E2EE keys on initial login
• Session recovery — bridge auto-reconnects when a user logs into the real LINE Chrome Extension
• SSE long-polling — use timeout-free HTTP client to prevent premature disconnects; context-based cancellation for clean shutdown
• OBS download reliability — retry on 404 and 202 (media still processing); graceful placeholders on failure
• Contact name updates — live contact renames propagate via SSE events with a TTL cache
• E2EE error matching — IsNoUsableE2EEGroupKey no longer false-matches token logout errors
• Video thumbnails — fixed double-close on temp file in extractVideoThumbnail
• Plain media routing — correct OBS type (m endpoint) for video/file plain receive
• Media captions — reject unsupported captions; use correct filename from Matrix
• Avatar sync — sync avatars for LINE business/official accounts; mark DM rooms correctly
• Registration YAML — fixed badly generated registration.yaml from docker-run script

💡 Refactoring

• Handler separation — message conversion split into pkg/connector/handlers/ with individual files per content type (call, image, video, audio, file, sticker, location, contact, text)
• WaitGroups — all goroutines (sync, poll, reactions, chat updates) tracked with sync.WaitGroup; Disconnect() waits for clean shutdown
• SSE context cancellation — ListenSSE accepts context.Context for proper cancellation instead of select/default polling
• Login key extraction — deeply-nested E2EE key chain logic extracted into fetchLoginKeys with early returns
• SSE client reuse — dedicated http.Client reused across SSE reconnects
• Thumbnail encryption — extracted encryptThumbnail helper to remove duplication

🤖 Chores

• Bump Chrome Extension version from 3.7.1 to 3.7.2
• Docker build caching improvements
