mcp_io_mqtt 0.2.1

MQTT v3.1.1 adapter for mcp_io. QoS 0 pub/sub with topic wildcard matching.

0.2.1 - 2026-05-23 - mcp_bundle 0.4.0 cascade

Changed (cascade)

• mcp_bundle caret bumped from ^0.3.0 to ^0.4.0.
• mcp_io caret bumped from ^0.2.0 to ^0.2.1.

mcp_io_mqtt does not touch UiSection.pages directly — caret-only cascade. Consumers should bump to ^0.2.1.

0.2.0 - 2026-05-04

• MQTT v5 — properties, reason codes, AUTH packet, shared subscriptions ($share/<group>/<filter>), client-side topic-alias LRU cache.
• QoS 1 / QoS 2 inflight tracking + persistent session (resume on sessionPresent=true).
• Will message + retain flag.
• Reason code → IoError mapping.

0.1.0 - 2026-04-28 - Initial Release
