ScalaCheck 1.14.3

Release notes

ScalaCheck 1.14.3 is a minor update from ScalaCheck 1.14.2, and it is binary compatible. This means that if you are using any other framework in combination with ScalaCheck, like ScalaTest or specs2 you can typically just bump the version of ScalaCheck in your build definition or wait for those libraries to transitively do it for you in their next update. You still need to make sure that the combination of frameworks you are using was built and tested together with each other, otherwise you can run into errors related to binary compatibility that are possibly very hard to debug.

If you're using ScalaCheck as your only testing framework, you can safely update your build definition to use the latest ScalaCheck release, although you might not see compilation errors but there may be deprecation warnings due to expected changes in ScalaCheck's API.

The detailed list of changes from the CHANGELOG for the 1.14.3. release are below.
