The headline above could fit in a tweet, but Drizzle making its first release almost 3 years after the project started deserves a blog post.
Brian Aker has a long blog post looking back at these 3 years (and even longer into MySQL history). Stewart Smith has an entertaining personal perspective. .frm files, I will not miss you (if I were to start using Drizzle, that is). Planet Drizzle has an avalanche of posts from most Drizzle devs celebrating this event.
