ScalaTest/Scalactic 3.0.6 Release Notes

ScalaTest/Scalactic 3.0.6 (for Scala 2.10, 2.11 and 2.12) includes the enhancements and bug fixes listed below. No source code using ScalaTest/Scalactic 3.0 or higher should break, but you will likely need to do a clean build to upgrade. Unfortunately, this release was accidentally not binary compatible with 3.0.5. We recommend you use 3.0.8 or higher instead.

For information on how to include ScalaTest in your project, see the install page. For information on how to use Scalactic in your production code, see its install page.
