We'll see if we get more testing inside master tree.

@claudep I am trying out the version from master in my project and it seems to be working well for me, although my requirements are fairly simple - basically just doing some configuration of the editor toolbar, and using HtmlField to store it in my models.

An official release would be great - I was using https://github.com/django-ckeditor/django-ckeditor but that is now stuck on an insecure, unsupported version, and this would be a good replacement.

Thanks a lot for the feedback! I guess that #460 is still more or less a blocker, and should be solved (either by upstream or us removing the offending lines) before pushing a new release.
