<Update label="June 5, 2026" description="Unreleased · latest core v0.16.2, stream v0.8.3, react v0.8.3, ui v0.8.3" tags={["Features"]} rss={{ title: "June 5, 2026 — @m4trix/core updates", description: "replace channel sinks with proxy consumers" }}>
  ### Breaking changes

  * replace channel sinks with proxy consumers (`matrix`) **BREAKING** ([90871b6](https://github.com/Pascal-Lohscheidt/m4trix/commit/90871b64d9dbe07a87e3f1c5de8c2c529bdd92d9))

    Add channel proxy declarations, explicit SSE proxy consumers, custom proxy registration, and inbound event publishing through InteractiveProxyHandle.

    BREAKING CHANGE: AgentNetwork setup now provides `proxy` instead of `sink`, channels use `.proxy(...)`/`getProxies()` instead of `.sink(...)`/`getSinks()`, and `network.expose()` now accepts proxy consumers such as `registerSSEStream(...)` instead of `\{ protocol, select }` options.
