+In the past few months, we delivered not only a bunch of awesome features but also some critical bug fixes. Moreover, we refactored CodiMD's backend and started to write new tests.
+
+To make it easier to maintain, we dropped legacy code, reorganize the repository, and add new documentation. For these reasons, we decided to make a huge leap toward version 2.0.0.
+
+Here are the highlights coming from version 2.0.0:
