 ------------
 
-- ...
+- The ``Standard`` style option specifies which version of C++ should be used
+  when parsing and formatting C++ code. The set of allowed values has changed:
+  - ``Latest`` will always enable new C++ language features.
+  - ``c++03``, ``c++11``, ``c++14``, ``c++17``, ``c++20`` will pin to exactly
+    that language version.
+  - ``Auto`` is the default and detects style from the code (this is unchanged).
+ The previous values of ``Cpp03`` and ``Cpp11`` are deprecated. Note that
+ ``Cpp11`` is treated as ``Latest``, as this was always clang-format's behavior.
+ (One motivation for this change is the new name describes the behavior better).
