Panel: The powerful data exploration & web app framework for Python
This minor release packs many exciting new features, specifically a new panel.chat subpackage containing components with powerful capabilities for interacting with LLM whether local or remote. Secondly this release adds compatibility with Param 2.0 bringing powerful new features including the ability to leverage reactive expressions using the rx wrapper and deeper support for reactively linking parameters, expressions and bound functions on Panel components. Lastly we overhauled the OAuth implementations adding support for code authorization and password based OAuth grant workflows and automatically refreshing the access_token when it expires. Beyond that this release includes many enhancements and numerous bug fixes. Special thanks to our first time contributors @aktech and @monodera and returning contributors @cdeil, @pierrotsmnrd and @TheoMartin. We also want to highlight the contribution of our new core contributor @ahuang11 for developing the chat components and recognize @MarcSkovMadsen and @philippjfr for their efforts on testing and improving these new components. Finally we thank the entire core team @Hoxbro, @MarcSkovMadsen, @maximlt, @ahuang11 and @philippjfr for their continued efforts.

Specifically it adds support for notifying users when the page is ready and when the Websocket disconnects using corresponding config options and upgrades the Vizzu version, thereby adding support for tooltips and enabling animations when the data is updated. The bug fixes are primarily focused on ensuring components such as GridStack and Tabulator render correctly and do not unnecessarily re-render or reload stylesheets.
