This might come across as a bit 'gushy' but it really has had a massive impact on what I am working on and what it enables us to do.<p>I've been evaluating WYSIWYG editors to use in one of our main products for about a year now. I stopped looking when I saw CK5 back in Alpha 1.<p>It ticked all of the boxes: modern build architecture, easily extensible, diffs/deltas/transform-ops at the core for collaborative services -- it's made for today and the future. And so much more than that. Where CK4 was great for what is now legacy browsers, CK5 is completely fresh and new for current & future browsers.<p>I highly recommend checking it out and to absolutely consider using it in a project that needs any form of rich text editing.
