+- 📂 Users can upload a directory of files with [`st.file_uploader`](/develop/api-reference/widgets/st.file_uploader) or [`st.chat_input`](/develop/api-reference/chat/st.chat_input).
+
+**Notable Changes**
+
+- 🏷️ You can configure the labels of options in [`SelectboxColumn`](/develop/api-reference/data/st.column_config/st.column_config.selectboxcolumn) with a new `format_func` parameter ([#12232](https://github.com/streamlit/streamlit/pull/12232), [#6795](https://github.com/streamlit/streamlit/issues/6795)).
