+## v3.0.0
+### Breaking changes
+v3 removes external dependencies from the core TestStack.ConventionTest project. 
+
+1. Mono.Cecil is now ILMerged internally  
+So if you use the Mono.Cecil functionality, leave it installed. Otherwise uninstall it to remove unneeded dependencies
+2. ApprovalTests is no longer a dependency  
+This also means the `Convention.IsWithApprovedExeptions` method is gone.  
+Replace usage with `var failures = Convention.GetFailures` then use Shouldly's `failures.ShouldMatchApproved()` extension or `ApprovalTests.Verify(failures)` to verify the failures.
