# MCP Mesh Release Notes

## v2.2.0 (UNRELEASED)
[Full Changelog](https://github.com/dhyansraj/mcp-mesh/compare/v2.1.0...v2.2.0)

## v2.2.0 (2026-05-19)

The MeshJob substrate gains a second-direction primitive: a per-job, ordered, append-only event log every running job carries, with cross-runtime parity across Python, TypeScript, and Java. Closes the sub-iteration gap left by the v2.0 progress-only surface — handlers can now drain events inline instead of polling state agents at iteration boundaries — and adds an observer iterator so multiple subscribers can mirror the same job's events independently without disturbing the producer's drain.
