Breaking Changes

●Issue #1

Native bokeh chart support has been removed; replace `st.bokeh_chart` usage with alternative chart libraries or custom components.

●Issue #2

`add_rows` command now includes a deprecation note; update code to avoid relying on deprecated behavior and migrate to newer data handling APIs.

●Issue #3

Keyword‑argument support for `st.vega_lite_chart` is deprecated; stop passing kwargs and use the explicit parameters instead.

Migration Steps

  1. 1
    Remove any usage of `st.bokeh_chart` or other native bokeh chart APIs.
  2. 2
    Update calls to `add_rows` to follow the new non‑deprecated behavior or replace them with alternative data‑handling functions.
  3. 3
    Stop passing arbitrary keyword arguments to `st.vega_lite_chart`; use the explicit parameters documented in the API.
  4. 4
    For `st.file_uploader` and `st.camera_input`, provide a stable `key` argument to maintain widget state across reruns.
