+## [0.5.0]
+
+### Changed
+
+* The plugin artifact is now published under the `org.typelevel` group ID. An artifact migration has been added to Scala Steward, so Scala Steward users should not have to update the artifact group ID manually.
+
+* The project now makes use of the [scalac-options](https://github.com/typelevel/scalac-options) library, so symbols relating to scalac options and their availability on differing Scala versions have been moved to the package `org.typelevel.scalacoptions`.
+
+* All other symbols provided by this plugin have been moved to the `org.typelevel.sbt.tpolecat` package.
+
+*  A Scalafix migration is available, and can be applied using the `github:` scheme, e.g.
+
+  ```bash
+  $ scalafix github:typelevel/sbt-tpolecat/v0_5?sha=v0.5.0
+  ```
+
+  or via the `dependency:` scheme, e.g.
+
+  ```bash
+  $ scalafix dependency:[email protected]::sbt-tpolecat-scalafix:0.5.0
