We would like to let you know that the second developer preview of CKEditor 5 has recently been tagged as version v0.2.0.
The first developer preview of CKEditor 5 was the first demo-able version. Its development took us 2 years and resulted in over 400 closed tickets and, most importantly, the creation of a powerful editing engine, editor architecture and a few basic features.
Such intensive initial development period had to lead to many unclosed businesses and a lot of ideas for refactoring. Hence, in iteration 2 (v0.2.0) we were focused on the most important architecture changes and project cleanup. As a result, in iteration 3 we will be able to focus on rapid feature development.
