- Added font weight logic to formatMessageAsText and formatMessage
- User's own @nickname appears bold (weight: .bold)
- Other nicknames remain medium weight
- Helps visually distinguish own messages from others
- Simplified getSenderColor to always return primary color
- Removed RSSI color calculation logic from formatMessageAsText
- Removed RSSI color calculation logic from formatMessage
- All sender names now use consistent green color
- RSSI information remains visible only in peer list
- Cache getRSSIColor results with key format: "\(rssi)_\(isDark)"

- Use minimal vertical padding (1px) between messages
- Remove LazyLinkPreviewView, use LinkPreviewView directly
- URLs now appear highlighted in message text AND show preview below
- Reduce VStack spacing from 4 to 2 and nested VStack from 2 to 0
- Set list row insets top/bottom to 0 to minimize spacing on iPhone
- Remove all markdown link parsing and formatting

- Improve write queue processing with additional safety checks
- Update activity tracking when processing queued writes
These fixes address UI glitches and improve Bluetooth reliability.
Always accept handshake initiations even with valid sessions, as the peer must have cleared their session for a good reason (e.g., decryption failure). This prevents deadlock where one peer has no session while the other maintains an invalid one.
- Add peer presence tracking with lastHeardFromPeer to detect reconnections
- Automatically send identity announcement when detecting peer reconnection after 30s
- Clear stale sessions when receiving handshake from recently-seen peer (likely restart)
- Add peers to activePeers when successfully decrypting their messages
- Fix thread safety in handshake coordinator with concurrent collections
- Extend message delivery timeouts (30s→120s private, 60s→180s room, 300s→600s favorite)
- Add per-peer encryption queues to prevent nonce desynchronization
- Make NoiseSession encrypt/decrypt operations thread-safe with barrier flag
- Initialize lastSuccessfulMessageTime when handshake completes
- Send identity announcement when decryption fails to prompt session reset
- Improve handshake state logging and debugging
This fixes:
- Peers stuck in "establishing encryption" after restart
- Nonce desynchronization causing "Decryption failed at nonce N"
- Asymmetric peer visibility (one peer sees the other but not vice versa)
- Thread safety issues causing crashes with pendingPrivateMessages
- Sessions marked as stale immediately after establishment
- Remove channel UI elements from ContentView
- Remove channel data structures and methods from ChatViewModel
- Remove channel commands (/j, /leave, /channels)
- Remove channel field from BitchatMessage protocol
- Remove channel message types and handling
- Remove NoiseChannelEncryption.swift entirely
- Clean up all channel references across the codebase
- Fix compilation warnings (var to let conversions)
- Remove all outdated test files that used incorrect APIs
- Simplify app to only support public broadcast and 1:1 private messages
- Replaced all print() calls with appropriate SecureLogger.log() calls
- Used proper categories: noise, encryption, session, security
- Applied appropriate log levels: debug, info, warning, error
- Converted 25 prints in BluetoothMeshService.swift
- Converted 1 print in ChatViewModel.swift
- Converted 8 prints in DeliveryTracker.swift
- Test files kept as-is for debugging purposes
- Verified successful build on iOS
This improves security by using structured logging that can filter sensitive data.

- Changed toolbar text from "bitchat*" to "bitchat/" with tighter spacing
- Removed blue intro message when no peers are connected
- Changed RSSI indicator back to simple dot instead of radiowaves icon
- Added triple-tap gesture on chat area to clear current context
- Improved LinkPreviewView performance with metadata caching
- Moved link previews closer to messages for better visual connection
- Fixed AppInfoView duplication by consolidating strings into single location
- Better error handling for link preview ATS errors
In my testing the app crashes in the background when receiving a notification. This is probably due to UIFeedbackGenerator requiring the main thread which isn't available
- Moved encryption/handshake status icons to appear after peer names in sidebar and private message headers
- Converted private messages and channels to slide-over views with smooth transitions
- Added swipe-right gesture to dismiss private chats and channels
- Added vertical separator bars to slide-over views for visual consistency
- Add version negotiation messages (0x20 versionHello, 0x21 versionAck)
- Implement VersionHello and VersionAck message types with platform info
- Add ProtocolVersion struct for version management and negotiation
- Update BinaryProtocol to check supported versions
- Add version negotiation to connection flow before Noise handshake
- Maintain backward compatibility with legacy peers (assume v1)
- Add comprehensive test suite with 40+ test cases
- Update documentation with version negotiation details
This ensures BitChat clients can negotiate protocol versions for smooth
upgrades while maintaining full backward compatibility with existing clients.

- Apply validation in both channel and regular message handling
- Add validation at retry service level to prevent queuing empty messages
- This fixes the phantom space issue between synced messages
- Introduce thread safety for recentlySentMessages using NSLock to prevent race conditions.
- Adjust message delay parameters for faster synchronization: reduce min/max message delays and adjust initial announce timing.
- Update sendMessage and sendEncryptedRoomMessage methods to accept optional messageID and timestamp parameters for better tracking.
- Improve message deduplication logic in ChatViewModel to prevent duplicates from being added when echoing back sent messages.

Implemented user blocking functionality:
- /block <nickname> - blocks a user from private messaging and ignores their messages in channels
- /block - lists all blocked users
- /unblock <nickname> - unblocks a user
Implementation details:
- Blocks are stored by public key fingerprint for persistence across sessions
- Blocked users cannot send private messages or have their public messages displayed
- Blocked users are silently ignored (they don't know they're blocked)
- Blocking a user automatically removes them from favorites

- Improved command help display with alphabetization
- Renamed 'rooms' to 'channels' throughout entire codebase
Critical fixes:
1. Match messages by sender nickname in addition to peer ID (since peer IDs change)
2. Send read receipts to CURRENT peer ID, not old senderPeerID from message
3. Remove requirement for senderPeerID to be non-nil (blocks older messages)
4. Add extensive logging to trace the flow
The core issue was that peer IDs are ephemeral and change between sessions:
- Rick sends message with peer ID A
- Later, Jack connects to Rick who now has peer ID B
- Read receipt needs to be sent to B, not A
- Messages need to be matched by nickname, not just peer ID
- Added logic to prevent downgrading from 'read' status to 'delivered'
- When an ACK arrives after a read receipt, the read status is preserved
- This fixes the issue where blue checkmarks briefly appear then revert to green
- Applied fix to all message types (main, private, room)
- Added app activation observer to send read receipts when app becomes active
- Send read receipts for all unread messages when receiving a new message while chat is open
- Added import for NSApplication/UIApplication notifications
- This ensures messages are marked as read even when opening chat from notifications or returning to app
- Added delay to ensure messages are loaded before checking

- Added onAppear handler to send read receipts when view loads
- Added detailed logging to debug the flow
- Now correctly identifies received messages that need read receipts
- Changed back to bold blue double checkmarks for read status
- Send read receipts for both 'sent' and 'delivered' status messages
- Added onChange handler to send read receipts whenever switching to a private chat
- Made markPrivateMessagesAsRead public so it can be called from views
- This ensures read receipts are sent when opening a chat from notifications or any other way
- Read receipts were being sent to the current ephemeral peer ID instead of the message's senderPeerID
- This caused read receipts to be lost when peer IDs changed between sessions
- Now using message.senderPeerID consistently for all read receipt sending
- Added detailed logging to track which peer ID receives the read receipt
- Add logging to track what delivery status is shown in UI
- Add logging when green/blue checkmarks appear
