### Fixes
- [#8179](https://github.com/gradio-app/gradio/pull/8179) [`6a218b4`](https://github.com/gradio-app/gradio/commit/6a218b4148095aaa0c58d8c20973ba01c8764fc2) - rework upload to be a class method + pass client into each component. Thanks @pngwn!
- [#8118](https://github.com/gradio-app/gradio/pull/8118) [`7aca673`](https://github.com/gradio-app/gradio/commit/7aca673b38a087533524b2fd8dd3a03e0e4bacfe) - Add eventsource polyfill for Node.js and browser environments. Thanks @hannahblair!
We have added a `max_file_size` size parameter to `launch()` that limits to size of files uploaded to the server. This limit applies to each individual file. This parameter can be specified as a string or an integer (corresponding to the size in bytes).
The following code snippet sets a max file size of 5 megabytes.
When a component encounters an error, the error state shown in the UI can now be cleared by clicking on the `x` icon in the top right of the component. This applies to all types of errors, whether it's raised in the UI or the server.

#### New `ImageEditor` component ([#6169](https://github.com/gradio-app/gradio/pull/6169) [`9caddc17b`](https://github.com/gradio-app/gradio/commit/9caddc17b1dea8da1af8ba724c6a5eab04ce0ed8))
A brand new component, completely separate from `Image` that provides simple editing capabilities.
- Set background images from file uploads, webcam, or just paste!
- Crop images with an improved cropping UI. App authors can event set specific crop size, or crop ratios (`1:1`, etc)
- Paint on top of any image (or no image) and erase any mistakes!
- The ImageEditor supports layers, confining draw and erase actions to that layer.
- More flexible access to data. The image component returns a composite image representing the final state of the canvas as well as providing the background and all layers as individual images.
- Fully customisable. All features can be enabled and disabled. Even the brush color swatches can be customised.

The paste-from-clipboard was not triggering an upload event. The clear button was not triggering a change event. The change event was triggering infinitely. Uploaded images were not preserving their original names. Uploading a new image should clear out the previous image. Thanks [@freddyaboulton](https://github.com/freddyaboulton)!

- [#6279](https://github.com/gradio-app/gradio/pull/6279) [`3cdeabc68`](https://github.com/gradio-app/gradio/commit/3cdeabc6843000310e1a9e1d17190ecbf3bbc780) - Ensure source selection does not get hidden in overflow. Thanks [@hannahblair](https://github.com/hannahblair)!
- [#5373](https://github.com/gradio-app/gradio/pull/5373) [`79d8f9d8`](https://github.com/gradio-app/gradio/commit/79d8f9d891901683c5a1b7486efb44eab2478c96) - Adds `height` and `zoom_speed` parameters to `Model3D` component, as well as a button to reset the camera position. Thanks [@abidlabs](https://github.com/abidlabs)!
#### Improve startup performance and markdown support ([#5279](https://github.com/gradio-app/gradio/pull/5279) [`fe057300`](https://github.com/gradio-app/gradio/commit/fe057300f0672c62dab9d9b4501054ac5d45a4ec))
##### Improved markdown support
We now have better support for markdown in `gr.Markdown` and `gr.Dataframe`. Including syntax highlighting and Github Flavoured Markdown. We also have more consistent markdown behaviour and styling.
##### Various performance improvements
These improvements will be particularly beneficial to large applications.
- Rather than attaching events manually, they are now delegated, leading to a significant performance improvement and addressing a performance regression introduced in a recent version of Gradio. App startup for large applications is now around twice as fast.
- Optimised the mounting of individual components, leading to a modest performance improvement during startup (~30%).
- Corrected an issue that was causing markdown to re-render infinitely.
- Ensured that the `gr.3DModel` does re-render prematurely.
From the backend, streamed outputs are served from the `/stream/` endpoint instead of the `/file/` endpoint. Currently just used to serve audio streaming output. The output JSON will have `is_stream`: `true`, instead of `is_file`: `true` in the file data object. Thanks [@aliabid94](https://github.com/aliabid94)!
