Thanks to all our 200+ contributors, we are announcing a release candidate for the upcoming release. On top of a few exciting features, we're also deprecating positional arguments in many places where the constructor/method accepts many arguments. for example, SVC(.5, "poly") will need to be expressed as SVC(C=.5, kernel="poly"), and SVC(C, kernel) as SVC(C=C, kernel=kernel). Please give it a try and let us know if there are any issues for us to fix them for the final release.
