v0.4.0

v0.4.0 - TLS & Session Options

What's New

TLS Certificate Support

Custom CA Certificate: Load self-signed or private CA certificates for broker authentication
Client Certificates (mTLS): Full mutual TLS support with client certificate and key
Insecure Mode: Skip certificate verification for testing (use with caution!)

MQTT Session Options

Clean Session Toggle: Choose between persistent sessions (retained subscriptions/messages) or fresh starts
Subscription QoS: Configure QoS level (0, 1, or 2) for subscriptions
Last Will and Testament (LWT): Configure disconnect message with topic, payload, QoS, and retain flag

UI Improvements

Renamed "Exact ID" to "ID Suffix" with clearer status values
Added placeholder hints for empty Client ID field showing auto-generation behavior
All new options available in the server edit dialog

Bug Fixes

Extended reconnect delay for exact client ID to prevent session takeover kick loops (waits keep_alive + 2s)

Configuration Example

[[mqtt.servers]]
name = "secure-broker"
host = "mqtt.example.com"
port = 8883
use_tls = true
ca_cert = "/path/to/ca.pem"           # Custom CA
client_cert = "/path/to/client.pem"   # mTLS cert
client_key = "/path/to/client-key.pem"
clean_session = false                  # Persistent session
subscribe_qos = 1                      # At least once
lwt_topic = "clients/mqtop/status"
lwt_payload = "offline"
lwt_retain = true
