 Mill's `--watch` flag watches both the files you are building using Mill, as
 well as Mill's own `build.sc` file and anything it imports, so any changes to
 your `build.sc` will automatically get picked up.

 ## Changelog
 
+### 0.2.5
+
+- Add `.runBackground` and `.runMainBackground` commands, to run something in
+  the background without waiting for it to return. The process will keep running
+  until it exits normally, or until the same `.runBackground` command is run a
+  second time to spawn a new version of the process. Can be used with `-w` for
+  auto-reloading of long-running servers.
+
+- [Scala-Native support](http://www.lihaoyi.com/mill/page/common-project-layouts.html#scala-native-modules).
+  Try it out!
+
+- Add `--disable-ticker` to reduce spam in CI
+
+- Fix propagation of `--color` flag
+
 ### 0.2.4
 
 - Fix resolution of `scala-{library,compiler,reflect}` in case of conflict
