Fluentvalidation 8.0-preview1 is now available. This is a major release with several breaking changes.

The biggest change is that validators should now inherit from ValidatorBase rather than AbstractValidator so you can take advantage of the new rule caching that’s available in FluentValidation 8. This change has been reverted for now and removed from preview2 due to some critical issues which were found.

Please check out the upgrade guide. If you run into any issues, please post them on the GitHub project site
