The second one is not as important as the main deps.

Hello, I have been doing this in my fork. Everything is still working, but my changes for additional common events are included. I will wait until that one is merged to open another pull request.

Would it make sense to have different releases for different Angular versions? I was thinking about to go with Angular versions e.g. 9.x.x or 8.x.x for previous version.

Hello @ezintz,

dependencies of ckeditor4-angular package are rather minimal - only load-script and tslib (see on NPM) so I'm not sure if there is any sense in having different releases for different Angular versions. Do yo think there could be any issue with newer/older Angular versions with those deps?

As for devDependencies we have an issue with @angular-devkit/build-angular dependency which requires [email protected] and so we cannot build docs (ckeditor4-docs) with never than 10 version of node (because it is used there too).
