Version 1.50.0

[mathcatsand]

Highlights

• Introducing MultiselectColumn to configure colorful, editable lists in your dataframes.

• Announcing color palette configuration options to set the exact shade of red, orange, yellow, green, blue, violet, and grey to use in Markdown, status elements, sparklines, st.metric, and st.badge.

• st.bar_chart has a new sort parameter for conveniently sorting your bars.

Notable Changes

• To prevent widgets from resetting when you change a parameter, widgets are transitioning to an identity based only on their keys (if provided). The following widgets use only their key for their identity:

  • st.button

  • st.download_button

  • st.checkbox

  • st.toggle

  • st.text_area

  • st.text_input

  • st.number_input

  • st.time_input

  • st.date_input

  • st.selectbox

  • st.multiselect

  • Custom components

• You can configure the color of chart columns.

• st.metric supports decimal.Decimal types (#12377, #12308). Thanks, aebrahim!

• You can specify the sample rate for st.audio_input, and the default sample rate has been reduced to 16000 Hz.

• For clarity, in st.plotly_chart, **kwargs is deprecated and replaced by config (#12291, #12280). Thanks, zyfy29!

• st.line_chart and st.graphviz_chart have width parameters to use with flex containers.

• You can configure st.table borders to show all, only horizontal, or no lines.

• You can specify a default tab in st.tabs.

• To use hosted fonts from providers like Google and Adobe, you can declare externally hosted fonts with a URL to their CSS file in theme.font, theme.headingFont, and theme.codeFont.
