 sbt-ci-release. A release is made by pushing a tag to GitHub.
 
 The plugin also brings in
-  - sbt-travisci to set the `scalaVersion` and `crossScalaVersions`
   - sbt-dynver to set the `version` based on the git history
+  - sbt-version-policy to check the versioning policy using MiMa
   - sbt-header to automate copyright header maintenance
-  - sbt-mima-plugin to maintain binary compatibility
   - sbt-osgi, if enabled with `scalaModuleOsgiSettings`
-  - sbt-version-policy to check the versioning policy
 
 ## Usage
 
 Add the plugin to the `project/plugins.sbt` file:
 
 ```
-addSbtPlugin("org.scala-lang.modules" % "sbt-scala-module" % "2.2.3")
+addSbtPlugin("org.scala-lang.modules" % "sbt-scala-module" % <version>)

 These additional settings are enabled by `scalaModuleSettings`:

+  - `Compile / compile / scalacOptions ++= Seq("-feature", "-deprecation", "-unchecked", "-Xlint")`
   - A `projectName.properties` file is generated and packaged
-  - `fork in Test := true` to work around some classpath clashes with scala-xml

 The following settings are also available:
