 # Docs changelog
 
+**3 April 2026**
+
+We've published documentation for the GitHub Copilot SDK, now available in public preview. These docs were migrated from the `github/copilot-sdk` repo and cover getting started, setup, authentication, usage patterns, hooks, observability, integrations, and troubleshooting.
+
+See [GitHub Copilot SDK documentation](https://docs.github.com/en/copilot/how-tos/copilot-sdk).
+
+<hr>

 **2 April 2026**
 
 We've expanded the documentation for custom agents in Copilot CLI, adding information about the built-in agents.

+In this exercise, you will learn how to:
+
+* Authenticate to {% data variables.product.prodname_registry %} using the `GITHUB_TOKEN`.
+* Build and publish container images to the {% data variables.product.prodname_container_registry %} (`ghcr.io`).
+* Use official Docker actions, such as `docker/login-action`, `docker/build-push-action`, and `docker/setup-buildx-action`.
+* Generate tags automatically with `docker/metadata-action` based on branches, pull requests, and releases.
+* Create features, pull requests, and releases with proper container versioning.

 Currently, our team is aware that there are limitations to this feature. Many of them are expected in leveraging our {% data variables.product.prodname_copilot_short %} API; however, there are a few that are specific to {% data variables.copilot.copilot_for_prs %} which pertain to limited scope, longer processing times, and inaccurate responses. We also note that users should expect terms used in their PR to appear in the AI-generated summary. This feature has been subject to RAI Red Teaming and we will continue to monitor the efficacy and safety of the feature over time.

 ### Limited scope
 
 Because of capacity, we know that larger pull requests that reference 30 or more files will require more time to be processed thoroughly. We don't have an exact threshold currently, but have observed the first 30 files being accounted for and then any additional files being omitted from the summarization. We are working to address this current scope limitation.
