+# Gerrit 3.0, and beyond
+
+Gerrit 3.0 it out! If you've tried 2.16, you may have already seen the new
+database backend (NoteDb) and UI (PolyGerrit). With 2.16 and 3.0, these features
+are better than ever. In Gerrit 3.0, we've deleted thousands and thousands of
+lines from Gerrit's codebase.
+
+Join me for a tour of new features you can use today, and a discussion about even
+more things to look forward to once we've freed ourselves from the burden of some
+of our legacy code.
