FluentValidation 2.0 beta 2 is now available for download. Here are the release notes:

Changes since 2.0 beta 1:

• Updated MVC integration to work with MVC3 RC
• Removed the v1.1 backwards compatibility layer. If you’re still using old-style custom validators (which were marked as Obsolete since v1.2), you will need to upgrade.
• Silverlight assembly renamed to FluentValidation.dll for consistency (formerly was FluentValidation.Silverlight.dll)
• Provide more useful information in ValidationException error message.
• Removed old mechanism for specifying cascade mode. Use .Cascade(cascadeMode) instead
• FluentValidatorModelMetadataProvider now converts NotNull/NotEmpty validators to IsRequired in metadata.
• Patch - updated German localization
• Using a child validator on a collection will now skip items in the collection that are null.
• NotEmptyValidator can now work against empty collections (for collections that implement ICollection)

All changes since 1.3:

• Performance improvements to AttributedValidatorFactory
• Fixed an issue where CascadeMode values are ignored if they're changed after the rules have been defined.
• Ported FluentValidation to WP7.
• ShouldHaveChildValidator test helper now works with child collection validators
• Simplified the implementation of SetValidator.
