streamlit 1.27.0

on Python PyPI

What's Changed

Highlights

• ✨ Introducing st.scatter_chart — a new, simple chart element to build scatter charts Streamlit-y fast and easy! See our documentation.
• 🔗 Introducing st.link_button! Want to open an external link in a new tab with a bit more pizazz than a plain-text link? Check out our documentation to see how.
• 🏃 Announcing the general availability of st.rerun, a command to interrupt your script and trigger an immediate rerun.

Notable Changes

• 👻 You can initialize widgets with an empty state by setting None as an initial value for st.number_input, st.selectbox, st.date_input, st.time_input, st.radio, st.text_input, and st.text_area!
• 📤 st.download_button now uses target="_self" instead of opening a new tab (#7151, #7132).
• 🧟 Removed unmaintained pympler dependency (#7193, #7131). Thanks, rudyardrichter!
