That was a pretty major change as it is, but as part of that conversion it also required an intense refactoring to move the mostly sync application to mostly async. I've written quite a bit about the conversion from the Internet Explorer based WebBrowser views to the Chromium based Edge WebView2 control which touched a lot of the code base. Building out these changes actually took a lot of effort - a lot more than I expected. Most of these features are internal and they affect the underlying foundation that Markdown Monster sits on. If these don't sound very exciting from an end user perspective, you are right.
If you've followed this blog and my Twitter feed, you've probably seen some of the discussions around my (mis)adventures around the process of building the update for this version. Markdown Monster is a sophisticated, yet easy to use Markdown Editor for Windows.
It's been a long road, but I've finally released Markdown Monster 2.0.
