- -Wunused-lambda-capture warns when a variable explicitly captured
by a lambda is not used in the body of the lambda.
+- -Wstrict-prototypes is a new warning that warns about non-prototype
+ function and block declarations and types in C and Objective-C.
+
+- -Wunguarded-availability is a new warning that warns about uses of new
+ APIs that were introduced in a system whose version is newer than the
+ deployment target version. A new Objective-C expression ``@available`` has
+ been introduced to perform system version checking at runtime. This warning
+ is off by default to prevent unexpected warnings in existing projects.
+ However, its less strict sibling -Wunguarded-availability-new is on by
+ default. It warns about unguarded uses of APIs only when they were
introduced
+ in or after macOS 10.13, iOS 11, tvOS 11 or watchOS 4.
+
+- The -Wdocumentation warning now allows the use of ``\param`` and
+ ``\returns`` documentation directives in the documentation comments for
+ declarations with a function or a block pointer type.
+
+- The compiler no longer warns about unreachable ``__builtin_unreachable``
+ statements.
