Change Control note Hiperspace --version 2.5.8 HiLang --version 2.5.8

The is null and is not null patterns are billed as

provide a clearer and more concise way to check for null values in C#. This change enhances readability and aligns with current C# best practices.

but the main advantage is that:

• You don't need to include ReferenceEquals in any operator == overload.
• name is not null is the same for reference (class) and value (struct) objects instead of ReferenceEquals(name, null) for classes and !name.HasValue for nullable values.
