This is the second and final release candidate before 1.0 — it's not a planned release candidate, but due to a flurry of activity and awesome PRs from FS2, Monix and Http4s contributors, we can't release a 1.0 with so much being added, a total of 35 PRs, which aren't light at all, a record for this project.
