Release History & Changelog

Builds

v1.7.1 No More Missed Notifications

November 5, 2026

Notifications Build 19

✓ Fixed: after leaving the app, new messages could be treated as already seen and show no notification.

v1.7.0 Reply From Notifications

November 5, 2026

Notifications Build 18

✓ Reply from the notification: type an answer without opening the app. If it cannot be sent, the notification stays and says why.
✓ Messenger and WhatsApp gateway chats now open on the right channel and chat when you tap their notification.

v1.6.2 Messages Stay Unread Until You Return

October 30, 2026

Read Status Build 17

✓ No more silent "read": if you leave the app with a chat open, new messages stay unread and keep their notification until you come back.

v1.6.1 All Unread Messages in the Notification

October 30, 2026

Notifications Build 16

✓ Conversation view: several unread messages from one customer now stack in one notification, like WhatsApp, instead of showing only the last one.

v1.6.0 Brand-Aware Notifications • Mark as Read

October 30, 2026

Notifications Build 15

✓ Opens the right line: tapping a notification opens the chat on the business number it came from.
✓ One notification per line: the same customer writing to both numbers now shows two notifications, each with the business name.
✓ Mark as read button: clear a message from the notification without opening the app.

v1.5.1 Persistent Session Cookie • Prevent Task Kill Sign-Out

October 20, 2026

Persistent Storage • Indestructible Session Build 14

✓ Persistent Cookie Jar: Replaced transient session cookies with permanent 10-year persistent cookies (Max-Age & Expires) immune to Capacitor's session cleanup.
✓ Recent Apps / Force-Stop Resistance: Swiping the app away from recent tasks or force-stopping never revokes your login session.
✓ Instant Zero-Click Restoration: On app restart, native SharedPreferences synchronously re-injects the session cookie before any network navigation occurs.

v1.5.0 Native Google Sign-In • Unlimited Device Session • RBAC Channel Security

October 19, 2026

Android Credential Manager • Secure Device Tokens Build 13

✓ Native Google Sign-In: Android Credential Manager bottom-sheet sign-in bypassing WebView restrictions. Instant silent sign-in on app boot.
✓ Unlimited Device Session: Permanent device token stored in private SharedPreferences and synced as HttpOnly cookie to WebView. Never expires while active.
✓ Authenticated Push Registration: FCM tokens registered with Bearer auth and linked to team member ID, enforcing per-channel push permissions.

v1.4.7 Clean Standard Notifications • High Reliability • Scale-Ready Architecture

October 04, 2026

Ultra-Lean Architecture • 0ms Tap Navigation Build 12

✓ Clean 1:1 Conversation Cards: Reliable per-chat notifications keyed to sanitized phone numbers (phone.hashCode()) with instant 0ms deep-link navigation into that chat room.
✓ Zero Ghost Summary Cards: Stripped artificial group summary wrappers and token synchronization overhead, avoiding OEM notification listener race conditions.
✓ Prepared for Omnichannel Scale: Clean notification contract ready for Facebook Messenger connection, Facebook comments, and AI-powered reply automations.

v1.4.6 Xiaomi HyperOS & MIUI InboxStyle Group Engine • Dedicated Summary ID

October 04, 2026

OEM Grouping Parity • Dedicated Summary ID 9999 Build 11

✓ Multi-Line InboxStyle Previews: Group summary notifications now construct dynamic multi-line sender previews matching WhatsApp Business, preventing Xiaomi HyperOS/MIUI from discarding empty summaries.
✓ Immunity to OEM Zero-Drop: Assigned positive constant SUMMARY_ID = 9999 so OEM notification listeners do not misinterpret ID 0 as null/uninitialized.
✓ FCM & Native Bridge Parity: Full feature synchronization between background push receiver and in-app webview bridge.

v1.4.5 Hardened Notification Group Bundling • Zero Drawer Splitting

October 04, 2026

WhatsApp-Authentic Notification Bundling • ID Alignment Build 10

✓ Unified Group Bundling: Group summary notifications are now always maintained with GROUP_ALERT_CHILDREN, preventing multi-contact chats from splitting apart or interleaving with third-party apps like WhatsApp.
✓ Normalized ID Hashing: Strict sanitization of phone digits ensures notification creation and dismissal IDs match identically across webview, FCM, and OS shade.
✓ Zero Orphan Card & Safe Teardown: Summary card is preserved as long as any unread chat is active in the tray, and cleanly wiped when the tray is cleared.

v1.4.4 Instant 0ms Launch • Zero Layout Shift • No Shaking

October 02, 2026

Ultra-Fast 0ms Cold Launch • Compositor Stability Fix Build 9

✓ 0ms Instant Launch: Removed the 1.5s artificial splash screen delay. The app reveals its UI immediately without holding a blank or splash screen.
✓ Eliminated Post-Open Shaking & Jitter: Removed GPU layer transform (translateZ(0)) that broke sticky header compositing on Android WebViews. Stabilized header height to WhatsApp's standard 56px.
✓ Zero-Flicker Conversation Hydration: Cached chats are painted synchronously on Frame 1, bypassing the skeleton loader completely if cached data is present.

v1.4.3 Authentic WhatsApp Document Viewer • FileProvider Cache Engine

October 02, 2026

WhatsApp Document UX • Native FileProvider Integration Build 8

✓ 3-State Document Morphology: Document bubbles dynamically transition from Pending (download icon) to Downloading (animated SVG spinner ring) to Cached (file open checkmark icon), matching official WhatsApp client behavior.
✓ Native Android Intent Dispatch: Replaced broken background DownloadManager queuing with direct background streaming into private cache storage (getCacheDir()/ig_docs) followed by immediate FileProvider handover to the phone's native PDF/Office viewer (Google Drive, Adobe Acrobat, WPS).
✓ Zero-Latency Instant Re-Open: Once downloaded, tapping the document instantly opens the cached local file without initiating another roundtrip network request.
✓ Web/PWA Inline Viewer: Desktop and mobile browsers open PDFs directly in the browser's native document viewer via Content-Disposition: inline rather than forcing unwanted file downloads.

v1.4.2 Native Gboard Paste • Over-The-Air Media & Album Engine

September 26, 2026

Live OTA Update • Auto-Synced (No APK Reinstall Needed) Service Worker v32

✓ Authentic WhatsApp Relative Timestamps: Conversation feed now mirrors WhatsApp's exact temporal formatting: today shows time (3:26 PM), yesterday shows Yesterday, past 6 days shows weekday (Thursday), and older chats show DD/MM/YYYY with vibrant green highlight on unread conversations.
✓ Sticky Chat Date Dividers: Distinct days in the conversation stream are cleanly partitioned by WhatsApp-style centered floating date badges (Today, Yesterday, 25 September 2026).
✓ WhatsApp 2x2 Album Collages: Consecutive photos and media bursts now automatically group into an authentic 2x2 collage grid with a frosted +N badge overlay, preventing vertical chat sprawl.
✓ Adaptive Aspect-Ratio Single Images: Single portrait receipts and tall payment screenshots (e.g. BRAC Bank Astha, bKash) adapt naturally up to 380px without cropping critical headers or reference numbers.
✓ Swipeable Gallery Lightbox: View high-res album photos with smooth mobile touch swipe gestures, next/prev arrow buttons, and keyboard navigation.
✓ WhatsApp Media Preview Screen: Stage photos, videos, and documents with full-width preview, custom captions, HD toggle, and 90° rotation baking before sending.

Native APK Core (v1.4.2 Binary)

✓ Native Gboard Clipboard Image Paste (Commit Content API): Tapping any copied image or screenshot in Google Keyboard (Gboard) clipboard now stages directly into the full-screen WhatsApp Media Preview screen. No more “InboxGuru does not support image pasting here” toast!

Live OTA Authentic WhatsApp Composer Capsule & Client-Side HD Engine

September 25, 2026

✓ Canvas 90° Rotation Baking: Swaps physical dimensions and bakes orientation transforms directly into exported image blobs before uploading.
✓ Desktop Clipboard & Drag-and-Drop: Native Ctrl+V screenshot paste and direct file drag-and-drop staging into the WhatsApp media canvas.

v1.4.1 Firebase Cloud Messaging & Zero Battery Drain

September 24, 2026

✓ Firebase Cloud Messaging (FCM): Replaced the OkHttp WebSocket foreground service with Google's own push infrastructure. Notifications now work even when the app is force-killed by the user or Android's battery optimization.
✓ Zero Battery Drain: Removed the persistent “Background Sync” notification from the status bar. No more always-on connections draining battery — FCM piggybacks on Android’s existing Google Play Services connection.
✓ OEM Battery Saver Compatible: Works reliably on Xiaomi MIUI, Oppo ColorOS, Samsung One UI, and Vivo FunTouch battery optimization modes — FCM is whitelisted by all major manufacturers.
✓ Reduced APK Permissions: Removed FOREGROUND_SERVICE, WAKE_LOCK, and RECEIVE_BOOT_COMPLETED — 4 fewer permissions for a cleaner install.

v1.3.0 Background Push Service, OkHttp Keep-Alive & Resilient Wakeup Sync

September 24, 2026

✓ Native OkHttp WebSocket Push Service: Continuous background sync service running directly in native Java with a 25s ping-pong keep-alive, guaranteeing notification delivery when the phone is locked or WebView is suspended.
✓ Resilient Resume & Wakeup Sync: Seamlessly reconnects dropped sockets and pulls fresh conversation updates immediately upon waking from sleep via visibilitychange and focus handlers.
✓ Active Chat Notification Suppression: Silently renders incoming messages in real-time when looking at that conversation, while firing heads-up cards for other incoming chats.
