Replace use_container_width with width, and pin streamlit - #1
Merged
Conversation
Streamlit renamed this flag and scheduled the old name for removal on 2025-12-31, a date that has already passed. It still works and only logs a warning, but this package declared "streamlit>=1.30.0" with no upper bound, so any future release could drop the old name and stop every chart, table and full-width button from rendering. All 9 sites were use_container_width=True on st.plotly_chart, st.dataframe or st.button, the three widgets where width="stretch" is the documented replacement. Found with an AST walk rather than a grep, so a call spanning several lines could not be missed, and st.image was confirmed absent: width there used to mean a pixel count. The floor moves to 1.60.0 because width is not accepted by the older releases the old floor allowed, so swapping the flag without raising it would have broken installs that were previously fine. Verified against 1.60.0, which is what is installed here. Capped below 2.0 so a major release cannot silently change widget APIs again. 212 passed, including the 10 dashboard tests that render the real app through AppTest.
