This release primarily aims at providing compatibility with Bokeh 3.2 and the upcoming Param 2.0 release. Additionally it includes a number of improvements including the ability to generate multiple outputs from a generator using the new 'append' mode and updates and fixes for Tabulator. We are also excited about the new Streamlit migration guide and a number of bug fixes.
