Revert "Release notes for 0.2.0"

For some strange reason, after committing SHA:
12e51f9ad017a897924b5b85fd29e8b62069869d, the website's CSS seems to not be
displayed anymore. I'm reverting this commit to understand if the fact is
coincidental or not.

This reverts commit 12e51f9ad017a897924b5b85fd29e8b62069869d.
