+
+**Notable Changes**
+
+- 🔲 [`st.metric`](/develop/api-reference/data/st.metric) and [`st.columns`](/develop/api-reference/layout/st.columns) have a parameter to show an optional border ([#9927](https://github.com/streamlit/streamlit/pull/9927), [#9928](https://github.com/streamlit/streamlit/pull/9928)).
+- 🎨 Text and background color in [Markdown](/develop/api-reference/text/st.markdown) can use the "primary" color from the `theme.primaryColor` configuration option ([#9676](https://github.com/streamlit/streamlit/pull/9676)).
+- 🥶 You can freeze columns with [column configuration](/develop/api-reference/data/st.column_config) to make them always visible when scrolling horizontally ([#9535](https://github.com/streamlit/streamlit/pull/9535), [#7078](https://github.com/streamlit/streamlit/issues/7078)).
+- 3️⃣ The `type` parameter for [buttons](/develop/api-reference/widgets/st.button) accepts a new option, `"tertiary"` ([#9923](https://github.com/streamlit/streamlit/pull/9923)).

+- 🪵 The [`client.showErrorDetails`](/develop/api-reference/configuration/config.toml#client) configuration option has additional values to show or hide more information ([#9909](https://github.com/streamlit/streamlit/pull/9909)).
+- 🔎 When Streamlit shows stack traces in the app for uncaught exceptions, internal code is omitted or reduced for easier debugging ([#9913](https://github.com/streamlit/streamlit/pull/9913)).
+- 📈 [`st.line_chart`](/develop/api-reference/charts/st.line_chart) shows tooltips for the nearest point on hover ([#9674](https://github.com/streamlit/streamlit/pull/9674)).
+- 🌐 [`st.html`](/develop/api-reference/utilities/st.html) will attempt to convert non-string objects with `._repr_html_()` before falling back to `str()` ([#9877](https://github.com/streamlit/streamlit/pull/9877)).
