All notable changes to Bull Bitcoin Mobile will be documented in this file.
- Real-time WebSocket notifications: Exchange updates (balance, KYC status, group membership) now arrive instantly via WebSocket instead of polling every 5 seconds, providing faster feedback and reducing battery drain
- Real-time support chat: Support messages now appear immediately without manual refresh via WebSocket push notifications
- Enhanced exchange settings menu: Added new functional screens including Recipients, Transactions, Default Bitcoin Wallets, App Settings, Secure File Upload, and Statistics
- Bitcoin wallets management: New screen to manage default Bitcoin, Lightning, and Liquid withdrawal addresses with edit/save/delete functionality
- Email notifications toggle: Added option in App Settings to enable/disable email notifications
- Secure file upload: New KYC document upload screen with status indicators (Upload, In Review, Accepted)
- Trading statistics dashboard: New Statistics screen showing buy/sell ratio, trade volumes, trade counts, average prices, and biller statistics
- Transaction filters: Added missing order type filters (Withdraw, Pay, Funding, Reward, Refund, Balance Adjustment) to exchange transactions page
- Exchange announcement banner improvements: Announcements now show truncated descriptions with ellipsis, and tapping opens a bottom sheet with full details
- Preferred currency improvements: Exchange home now properly handles empty balance currency, and deposit/withdraw/pay screens set initial dropdown values to preferred currency jurisdiction
- Backup warning overlay: Users are now shown a persistent overlay warning when their wallet backup is incomplete, preventing them from dismissing it by navigating away without addressing it.
- Scam consent warning for exchange funding: Users must explicitly consent to a scam warning before funding their exchange account, protecting against social engineering attacks
- Randomized OHTTP relay selection: OHTTP relay is now randomly selected on each payjoin call using
Random.secure()to prevent network-layer fingerprinting
- Self-transfer detection: Payjoin send now detects self-spent transactions and displays a "Self-transfer" row on the confirmation screen. Self-spends bypass payjoin.
- Close button on broadcasting screen: Added a Close button on the broadcasting/loading screen since the app no longer auto-progresses when autosync is disabled
- 11 new languages exposed in the language selector: 🇸🇦 Arabic, 🇧🇬 Bulgarian, 🇧🇩 Bengali, 🇨🇿 Czech, 🇬🇷 Greek, 🇮🇷 Persian, 🇮🇳 Hindi, 🇰🇷 Korean, 🇧🇷 Brazilian Portuguese, 🇹🇭 Thai, 🇹🇷 Turkish
- Opt-in error reporting program: Added optional, self-hosted error reporting (disabled by default) with explicit user consent toggle in App Settings. Only collects error reports and stack traces, no user behavior tracking or telemetry

- Price graph refresh: Users can now manually reload Bitcoin prices if automatic loading fails
- LN receive success screen crash: Fixed a UI crash that occurred when reaching the success screen after receiving via Lightning through the wallet receive pages
- Insufficient balance navigation: Improved error on insufficient balance and swap limits. Fixed an issue where clicking Continue on the send amount page with insufficient funds would show an error but still navigate to the confirm page
- Handle amountless invoice: Better handling of amountless invoices on swaps. Throws a more descriptive error.
- WebSocket reconnect loop: Fixed infinite reconnect loop where unauthenticated users would see repeated WebSocket connection errors every 5 seconds
- Exchange statistics improvements: Replaced circular progress indicators with linear ones, fixed trade count display to show plain integers, added currency conversion for statistics, and improved number formatting with thousands separators
- DCA confirmation text color: Fixed unreadable text color on DCA confirmation screen by using proper theme color
- Support chat attachments: Improved image picker flow with better permission handling and clearer error messages
- CA KYC Limited sell limit: Enforced the $999 CAD buy/sell limit for Canadian users with limited KYC verification, with proper form validation

- Recoverbull Orbot detection: Fixed Recoverbull connection by checking if Orbot is actually running on port 9050 instead of just checking user settings, preventing Tor-over-Tor connection errors
- Multiple dark theme fixes: Fixed various dark theme issues including QR code backgrounds (now hardcoded white for hardware wallet compatibility), PSBT flow instructions visibility, exchange logout bottom sheet theme, and Recoverbull button theme; also fixed custom Electrum server delete widget, "how to decide" bottom sheet, and exchange home KYC card

- Secure storage updates: Updated to Flutter Secure Storage 10.0.0 with improved iOS background task access and better Android compatibility. Should fix app startup issues
- Seed fetch retry logic: Added retry mechanism with exponential backoff (up to 5 attempts) when fetching seeds from secure storage to prevent false "Seed Not Found" errors during app startup
