+### Improvements
+
+- Ports sbt-cross-building's `^` and `^^` commands for plugin cross building. See below.
+
+### sbt-cross-building
+
+[@jrudolph][@jrudolph]'s sbt-cross-building is a plugin author's plugin.
+It adds cross command `^` and sbtVersion switch command `^^`, similar to `+` and `++`,
+but for switching between multiple sbt versions across major versions.
+sbt 0.13.16 merges these commands into sbt because the feature it provides is useful as we migrate plugins to sbt 1.0.
+
+To switch the `sbtVersion in pluginCrossBuild` from the shell use:
+
+```
+^^ 1.0.0-M5
+```
+
+Your plugin will now build with sbt 1.0.0-M5 (and its Scala version 2.12.2).
+
+If you need to make changes specific to a sbt version, you can now include them into `src/main/scala-sbt-0.13`,
+and `src/main/scala-sbt-1.0.0-M5`, where the binary sbt version number is used as postfix.
+
+To run a command across multiple sbt versions, set:
+
+```scala
+crossSbtVersions := Vector("0.13.15", "1.0.0-M5")
+```
+
+Then, run:
+
+```
+^ compile
+```
