[1.3.0] - 2026-02-22 "Social Network"

Added

Auto-Connect System

• New config option: autoconnect=1 connects automatically to configured server on startup
• Combined with nickpass=, provides fully automated login experience
• Eliminates manual /server command for regular users

NickServ Auto-Identification

• New config option: nickpass= for automatic NickServ identification after connect
• Separate from server password (pass=) for clarity
• Sends IDENTIFY <password> to NickServ immediately after registration completes

Friends Detection System

• New config options: friend1=, friend2=, friend3= to define up to 3 friend nicks
• Automatic ISON polling every 30 seconds to detect online friends
• Status bar indicator shows when friends are online
• WHOIS information displayed when friend comes online

Timestamps Toggle

• New command: /timestamps (alias /ts) toggles timestamp display
• New config option: timestamps=1 to enable by default
• Timestamps now shown consistently on all message types when enabled

Ping Latency Indicator

• Server response time measured and displayed after PING/PONG
• Helps diagnose connection quality issues
• Displayed in status messages when relevant

Automatic Nick Recovery (433 Handling)

• If nickname is in use during registration, automatically appends _ and retries
• Prevents connection failure due to nick collision
• User notified of alternate nick being used

UTF-8 Support

• Incoming UTF-8 text automatically converted to displayable ASCII
• Accented characters (áéíóúñüç) converted to base letters
• Emoji and other multi-byte sequences replaced with ?
• Enables readable chat with international users

Fixed

Reentrant Disconnection Bug

• Fixed race condition where multiple disconnect triggers could corrupt state
• Added disconnecting_in_progress guard flag
• Prevents crashes during network instability

Search Command Reliability

• Fixed rx_overflow not being reset in send_pending_search_command
• Prevents stale overflow state from corrupting search results

WHO/Search Parsing

• Implemented protocol-agnostic parsing for numeric 352 (WHO reply)
• Works correctly with different IRC server implementations
• Fixes /who and /search on non-standard servers

Message Formatting

• wrap_indent=0 now correctly applied after QUIT/KICK/KILL messages
• Prevents visual artifacts in subsequent messages

Optimized

Deep Code Optimization (4 passes)

• Library function elimination: Replaced strstr, strncmp, strcmp with specialized inline checks
• String deduplication: Consolidated 20+ duplicate string literals into shared constants
• ASM hot paths: Converted print_char64, print_str64, irc_param to optimized assembly
• SDCC codegen improvements: Applied __z88dk_fastcall and __z88dk_callee conventions throughout
• Table compression: Optimized command dispatch tables and help text pool
• Call fusion: Combined consecutive main_puts calls with main_puts2 helper

Memory Footprint

• Reduced command history buffer from 128 to 96 bytes per entry (128 bytes BSS saved)
• Eliminated unused static buffers
• Consolidated toggle command implementations

Changed

Configuration File Format

• !config display now shows all new options with formatted output
• Config parser extended for new keywords
• Maintains backward compatibility with v1.2 config files

Technical Notes

• Multiple optimization passes applied (see optimization reports r1-r4)
• Total estimated savings: ~500-800 bytes ROM across all optimizations
• New ASM routines: _utf8_to_ascii, _st_strchr
• New handlers: friends ISON/WHOIS processing
• Config parser extended for: autoconnect, nickpass, friend1-3, timestamps
