General
Enabled GM_cookie for all versions (HttpOnly cookie access still only at the beta versions)
Added a warning message when a script without @include and @match entry is saved the first time
UI
Show an error icon at scripts without any @include and @match entry
MV3
Improved script installation to not download the script content in parallel anymore
Note: you can restore the old behavior, by changing Userscript URL detection to Legacy
Known Issues
GM_webRequest is not (yet) supported in Manifest V3
GM_xhr fires only one progress event (you can use responseType stream for now)
In UserScript API Dynamic mode scripts that are using a RegExp @require cause overhead by being injected into every frame
Script installation is kind of clumsy because the script content is downloaded in parallel
