New Streamlit release: 0.47.2

Version 0.47.2

Release date: October 1, 2019


  • :sunrise_over_mountains: New showing off 4 glorious Streamlit apps. Try it out!
  • :arrows_counterclockwise: Streamlit now automatically selects an unused port when 8501 is already in use.
  • :gift: Sidebar support is now out of beta! Just start any command with st.sidebar. instead of st.
  • :zap: Performance improvements: we added a cache to our websocket layer so we no longer re-send data to the browser when it hasn’t changed between runs
  • :chart_with_upwards_trend: Our “native” charts st.line_chart, st.area_chart and st.bar_chart now use Altair behind the scenes
  • :gun: Improved widgets: custom st.slider labels; default values in multiselect
  • :female_detective: The filesystem watcher now ignores hidden folders and virtual environments
  • :nail_care: Plus lots of polish around caching and widget state management

Breaking change:

  • :shield: We have temporarily disabled support for sharing static “snapshots” of Streamlit apps. Now that we’re no longer in a limited-access beta, we need to make sure sharing is well thought through and abides by laws like the DMCA. But we’re working on a solution!
