panel 1.2.2

Version 1.2.2

on Python PyPI

This micro-release is likely the last in the 1.2.x series with a large number of bug fixes and a few enhancements to existing components. The enhancements include the ability to control the scroll position on a Column, improvements for authentication and authorization, the ability to add click event handlers to Perspective and a few other items. Bug fixes also center fixes for authentication, some improvements when rendering Tabulator avoiding various race conditions in its rendering pipeline, and fixes for Perspective, Echarts, DeckGL and a few other components.
