 - `Project(...)` constructor is restricted down to two parameters. Use `project` instead.
 - `sbt.Plugin` is also gone. Use auto plugins.
 - The incremental compiler, called Zinc, uses class-based name hashing.
-- Zinc drops support for Scala 2.8.x and 2.9.x.
+- Zinc drops support for Scala 2.8.x, 2.9.x., 2.11.1 and below.
 - Removed the pre-0.13.7 *.sbt file parser (previously available under `-Dsbt.parser.simple=true`)
 - Removed old, hyphen-separated key names (use `publishLocal` instead of `publish-local`)
 - Removes no-longer-documented old operators `<<=`, `<+=`, and `<++=`.
