Version 1.15.0

Notable Changes

  • :nail_care: Widget labels can contain inline Markdown. See our docs and demo app for more info.
  • :musical_note: st.audio now supports playing audio data passed in as NumPy arrays with the keyword-only sample_rate parameter.
  • :repeat: Functions cached with st.experimental_memo or st.experimental_singleton can contain Streamlit widgets using the experimental_allow_widgets parameter. This allows caching checkboxes, sliders, radio buttons, and more!

As a musician and audio engineer (in my spare time) I love this update for st.audio :heart:

This release seems to have broken the Streamlit Altair theme for charting (this link used to show a demo but that seems down now too: https://share.streamlit.io/app/streamlit-feature-demos-altairstreamlitstreamlit-app-260ynr/)

At least, the pattern for applying the Streamlit theme has changed - you can still specify it on a chart by chart basis but that global command seems to no longer work.
