@fredzannarbor @knorthover Just to be clear, we won’t be removing st.cache right away. We’ll show a deprecation warning in the logs if you keep using it in new Streamlit versions. But we’ll only remove it in a future major version of Streamlit (i.e. 2.0 or 3.0 – which we are not even thinking about yet). We absolutely want to make sure we don’t break old apps and this transition is not a pain in the a** for you
