 - `[[maybe_unused]]` **Visual Studio 2017 version 15.3 and later:** (Available with [`/std:c++17`](../build/reference/std-specify-language-standard-version.md) and later.) Specifies that a variable, function, class, typedef, non-static data member, enum, or template specialization may be intentionally unused. The compiler doesn't warn when an entity marked `[[maybe_unused]]` isn't used. An entity that's declared without the attribute can later be redeclared with the attribute and vice-versa. An entity is considered *marked* after its first declaration that's marked `[[maybe_unused]]` gets analyzed, and for the rest of the current translation unit.
 
-- `[[likely]]` **Visual Studio 2019 version 16.6 and later:** (Available with [`/std:c++20`](../build/reference/std-specify-language-standard-version.md) and later.) Specifies a hint to the compiler that the code path for the attributed label or statement is more likely to execute than alternatives. In the Microsoft compiler, the `[[likely]]` attribute marks blocks as "hot code", which increments an internal optimization score. The score is incremented more when optimizing for speed, and not as much when optimizing for size. The net score affects the likelihood of inlining, loop unrolling, and vectorizing optimizations. The effect of `[[likely]]` and `[[unlikely]]` is similar to [Profile-guided optimization](../build/profile-guided-optimizations.md), but limited in scope to the current translation unit.
