+# Changelog
+
+## 2.0.0-rc1 (2016-02-11)
+
+Time flies and it has been three years since this package was first released.
+There have been a couple of API changes I have wanted to do for some time but
+I've tried to maintain backwards compatibility. Some inconsistencies in the
+API have started to show, proper vendor support in Go out of the box and
+the fact that `go vet` will give warnings -- I have decided to bump the major
+version.
+
+* Make eg. `Info` and `Infof` do different things. You want to change all calls
+	to `Info` with a string format go to `Infof` etc. In many cases, `go vet` will
+	guide you.
+* `Id` in `Record` is now called `ID`
