June 2025: Delivered Telegram alert transport improvements in librenms/librenms to enhance incident notification relevance and reliability. Key changes include attaching images after the main message, configurable attachment handling (photos vs files), and adding message_thread_id to enable threading; POST requests now correctly apply query parameters. This work aligns with proactive alerting, reduces notification fatigue, and improves MTTR. Commit bb523c97635ea9e57ac661769f8c1f4c5f58e904 (Alert Telegram @signedGraphTag #17710 (#17867)).
