5.1.0

Enhancements

• Support for covariant method returns (@stakx, #619)

Bugfixes

• DynamicProxy emits invalid metadata for redeclared event (@stakx, #590)
• Proxies using records with a base class broken using .NET 6 compiler (@ajcvickers, #601)
• MissingMethodException when proxying interfaces containing sealed methods (@stakx, #621)
