###### Features

-   [#13685](https://github.com/gradio-app/gradio/pull/13685) [`6302098`](https://github.com/gradio-app/gradio/commit/6302098bc300df0dd36f2cbea904bafca03b208d) - `gr.Workflow`: auto-create input/output nodes for model nodes (as already happens for Space nodes), replace the "Input"/"Output" buttons with a single "Component" button whose direction is derived from wiring, rename "Data" to "Dataset", let node error messages be copied, and document the `oauth_token` parameter in the View API panel.  Thanks @abidlabs!
-   [#13688](https://github.com/gradio-app/gradio/pull/13688) [`321361f`](https://github.com/gradio-app/gradio/commit/321361fd8de9942e7046dcb54987d18a2a091e7e) - Workflow: resizable nodes, full-screen image view, and webcam/mic capture.  Thanks @abidlabs!
-   [#13697](https://github.com/gradio-app/gradio/pull/13697) [`3ac9d5d`](https://github.com/gradio-app/gradio/commit/3ac9d5db5892e88f57260215793feeaa06bdde59) - Fix release CI regressions for assets and bundles.  Thanks @abidlabs!

###### Fixes

-   [#13692](https://github.com/gradio-app/gradio/pull/13692) [`3676c45`](https://github.com/gradio-app/gradio/commit/3676c45acfc12456de097996fe5adab2132e2d30) - publish the `Prism` global before its grammar files load, so the docs pages stop failing to hydrate with `ReferenceError: Prism is not defined`.  Thanks @abidlabs!
-   [#13687](https://github.com/gradio-app/gradio/pull/13687) [`fd79d09`](https://github.com/gradio-app/gradio/commit/fd79d0999e66a3331a59d2ac80a7b61ec3e90f46) - Harden authentication and file redirect boundaries.  Thanks @abidlabs!
