Universal I/O Backbone for device integration into the MCP ecosystem. Provides device registry, policy engine, audit trail, streaming, command queue, and session management.

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 does not touch UiSection.pages directly, so this release is a caret-only cascade. Consumers should bump to ^0.2.1.

0.2.0 - 2026-05-04

• Long-running job lifecycle (JobManager + cooperative cancellation + progress URI subscribe).
• Runtime telemetry hooks (IoMetrics counter / gauge interface).
• MCP tool surface expanded to 11 tools (3 job-control tools added).
