Now the users of NNG can use NanoMQ to work as the bridge between Nanomsg Next-gen and MQTT ecosystem, just by configuration, no need to add one more proxy process.\u003C/p>\n\u003Cp>AI composed change log:\u003C/p>\n\u003Cp>We are thrilled to announce the release of NanoMQ v0.24.14!\u003C/p>\n\u003Cp>This version represents a major milestone in NanoMQ's robustness. Thanks to extensive fuzzing and rigorous code audits, we have patched several critical memory safety vulnerabilities. Alongside these security consolidations, we are introducing a brand-new offline message cache, NNG Pub/Sub bridging, and enhanced REST API querying capabilities.\u003C/p>\n\u003Cp>Upgrade is highly recommended for all users.\u003C/p>\n\u003Cp>🚀 New Features & Enhancements\nOffline Message Cache: Introduced a new offline message caching mechanism to improve data reliability for disconnected clients.\u003C/p>\n\u003Cp>NNG Pub/Sub Bridging: Added full support for NNG Pub/Sub bridging capabilities across both NanoMQ and NanoNNG.\u003C/p>\n\u003Cp>REST API Upgrades: The GET /api/v4/clients endpoint now supports multi-condition querying, giving you more granular control over client monitoring.\u003C/p>\n\u003Cp>CLI Enhancements: nanomq_cli now fully supports Will Properties for MQTT v5 client options.\u003C/p>\n\u003Cp>🛡️ Security & Stability\nThis release resolves several high-severity vulnerabilities and edge-case crashes, making the broker more resilient against malformed packets and malicious payloads:\u003C/p>\n\u003Cp>Pre-Auth Memory Safety: Fixed a critical memory corruption/integer underflow bug in the HTTP basic_authorize API.\u003C/p>\n\u003Cp>MQTTv5 Parser Hardening:\u003C/p>\n\u003Cp>Fixed a Double Free vulnerability in nni_mqtt_msg_decode_subscribe().\u003C/p>\n\u003Cp>Fixed a NULL pointer dereference (SEGV) in nni_mqttv5_msg_decode_connect().\u003C/p>\n\u003Cp>Patched multiple Heap Use-After-Free (UAF) bugs related to connection parameters and properties.\u003C/p>\n\u003Cp>HTTP API: Fixed an out-of-bounds bug in the HTTP post_msg API discovered via fuzzing.\u003C/p>\n\u003Cp>Safety Consolidation: Deployed multiple new boundary checkers and safety guards throughout the NanoNNG core.\u003C/p>\n\u003Cp>🐛 Bug Fixes & Optimizations\nWebhook: Fixed memory leaks that could occur during Webhook execution.\u003C/p>\n\u003Cp>QUIC: Fixed a type confusion issue triggered when closing QUIC dialers (nni_quic_dialer_close).\u003C/p>\n\u003Cp>Bridging: Added the missing SNI parameter to the bridge configuration parser.\u003C/p>\n\u003Cp>Codec Performance: Optimized property decoding logic by adding a tail node, significantly reducing complexity.\u003C/p>\n\u003Cp>Housekeeping: Removed obsolete code, cleaned up redundant logging, and added new internal flags.\u003C/p>\n\u003Ch2>What's
