+This release concludes endless months of hard work from the community. You, all
+users and contributors, deserve a big **thank you**.
+
+This project has been an increadible experience for me, your dear Guillaume,
+creator and maintainer of Radicale. After more than 8 years of fun, I think
+that it's time to open this software to its contributors. Radicale can grow and
+become more than the toy it used to be. I've always seen Radicale as a small
+and simple piece of code, and I don't want to prevent people from adding
+features just because I can't or don't want to maintain them. The community is
+now large enough to handle this.
+
+If you're interested in Radicale, you can
+read [#372](https://github.com/Kozea/Radicale/issues/372) and build its
+future.
