Highlights

• Announcing the general availability of st.user, a dict-like object to access information about the current user.

Notable Changes

• st.multiselect and st.selectbox have a new parameter to let users add new options.
• st.context has new attributes: url, ip_address, and is_embedded.
• Text alerts and exceptions have a new width parameter (#11142).
• You can set the tab index for st.components.v1.html and st.components.v1.iframe (#11065, #7969).
• When you pass a CSS file's path to st.html, Streamlit will automatically insert <style> tags and avoid creating extra space in the app (#10979, #9388, #10027).
• You can add an icon to the left of the value in st.text_input and st.number_input.
