## Highlights

* **Personal ChatGPT plan connections**: Self-hosted deployments can enable personal account sign-in and discover its available models; connections stay scoped to the signed-in user ([#4136](https://github.com/everruns/everruns/pull/4136)).
* **Stock subagents for custom hosts**: Library hosts can run the stock subagent and handoff tools through a store of portable runtime definitions, without constructing control-plane records ([#4078](https://github.com/everruns/everruns/pull/4078)).
