 New functionality:
 
 - Interface `C5.ICollection<T>` now extends generic interface `System.Collections.Generic.ICollection<T>`. The `C5.ICollection<T>` interface in some cases describe different exceptions than specified by `SCG.ICollection<T>`, but we have not attempted to fix this because the .NET collection implemented in some cases throw other exceptions than those specified anyway.
-
 - Interface `C5.IList<T>` now extends interface non-generic interface `System.Collections.IList`, so C5 list collections can be passed to .NET GUI components and other framework methods.
-
 - Exception-free methods
 
   - `bool TryPredecessor(T x, out T res)`
