Features

Kui now uses Markdown for its notebook source format. Previously, notebooks could only be authored within Kui itself, and the serialized form was a dump of the internal models.
Playground for Kui notebooks: https://playground.guidebooks.dev/ This is a static single page web app deployment of Kui! Source
Update to Electron 13, which allows us to ship signed+notarized builds for macOS. This should also yield some improvements to performance of certain commands, especially on macOS and Linux (due to an update to node-pty)
This release now presents offered notebooks in a sidebar with a hamburger menu toggler
