This build improves the browser and electron app compatibility quite a bit, it also adds a new web browser compatibility Template wizard allowing to create templates for previously unknown Chromium and Firefox (gecko) based browsers.
Please review the full Changelog thoroughly as it documents a bunch of new options which allow to control the new compatibility mechanisms and in case of unexpected issues will help to mitigate them.
There is a new revision of this update available 1.8.2a see the changelog and update.
Please note that with this build we have updated Inno Setup to 6.2.2 which comes with a new more modern icon, also as this is a pre-release build it is not fully signed (only the driver is).
