rumqttc v0.25.0 Release Notes

We're excited to announce the release of rumqttc v0.25.0! This release brings significant improvements, new features, and important bug fixes that enhance the stability and functionality of your MQTT applications.

🚀 What's New

Enhanced MQTT v5 Support

  • Session Management: Added support for session_expiry_interval in MQTT v5 connections, giving you better control over session persistence
  • Authentication Packets: Implemented MQTT v5 Auth packet support for enhanced authentication flows
  • Connection Properties: Made DisconnectProperties struct public for better disconnect handling

Security & Performance Improvements

  • Network Performance: Added TCP no_delay configuration option for reduced latency in time-sensitive applications
  • Memory Optimization: Replaced Vec with FixedBitSet for QoS 2 packet tracking, reducing memory overhead
  • Network Timeout: Set default network timeout to Duration::MAX instead of zero for better connection handling

Developer Experience Enhancements

  • TLS Support: Added native TLS TlsConnector support for more flexible secure connections
  • Client Configuration: New set_client_id method in MqttOptions for easier client ID management
  • External Auth: Re-enabled public access to external authentication features

🔧 Important Bug Fixes

Connection Stability

  • Fixed panic issues on connection closure
  • Resolved MQTT v5 packet writing problems that prevented outgoing packets from reaching the network
  • Improved event ordering in poll() method for more predictable behavior

Subscription Handling

  • Filter Validation: Added proper validation for subscription filters
  • Subscribe Many Fix: Resolved critical issue where subscribe_many always caused EmptySubscription errors

Packet Processing

  • Write Operations: Ensured all write operations return correct byte counts
  • PubAck Filtering: Fixed filtering of unexpected PubAck packets in event loop
  • Error Handling: Removed SubAck/UnsubAck/PubAck/PubRec/PubRel/PubComp reason code errors from critical state errors

📚 Code Quality & Maintenance

Dependency Updates

We've updated several critical dependencies for security and performance:

  • OpenSSL: 0.10.64 → 0.10.71
  • H2: 0.4.2 → 0.4.4
  • Rustls: 0.22.2 → 0.22.4
  • Various Go dependencies in benchmarks

Refactoring Highlights
