3.19.0

New Features:

Improved embedding experience

When embedding a spaces-hosted gradio app as a web component, you now get an improved UI linking back to the original space, better error handling and more intelligent load performance. No changes are required to your code to benefit from this enhanced experience; simply upgrade your gradio SDK to the latest version.

This behaviour is configurable. You can disable the info panel at the bottom by passing info="false". You can disable the container entirely by passing container="false".

Error statuses are reported in the UI with an easy way for end-users to report problems to the original space author via the community tab of that Hugginface space:

By default, gradio apps are lazy loaded, vastly improving performance when there are several demos on the page. Metadata is loaded ahead of time, but the space will only be loaded and rendered when it is in view.

This behaviour is configurable. You can pass eager="true" to load and render the space regardless of whether or not it is currently on the screen.

New gr.BarPlot component! 📊

Create interactive bar plots from a high-level interface with gr.BarPlot.
No need to remember matplotlib syntax anymore!

Example usage:

import gradio as gr
import pandas as pd

simple = pd.DataFrame({
    'a': ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I'],
    'b': [28, 55, 43, 91, 81, 53, 19, 87, 52]
})

with gr.Blocks() as demo:
    gr.BarPlot(
        simple,
        x="a",
        y="b",
        title="Simple Bar Plot with made up data",
        tooltip=['a', 'b'],
    )

demo.launch()

Bokeh plots are back! 🌠

Fixed a bug that prevented bokeh plots from being displayed on the front end and extended support for both 2.x and 3.x versions of bokeh!

By @freddyaboulton in PR 3212

Bug Fixes:

• Adds ability to add a single message from the bot or user side. Ex: specify None as the second value in the tuple, to add a single message in the chatbot from the "bot" side.
