   prints "value = 4,2".
 
-* Introduced the ``fmt::compile`` function that does format string compilation:
+* ``formatter`` specializations now always take precedence over ``operator<<``
+  (`#952 <https://github.com/fmtlib/fmt/issues/952>`_):

+  .. code:: c++

+     #include <iostream>

      // s == "42"
 
-  Thanks `@stryku (Mateusz Janek) <https://github.com/stryku>`_.
+  It moves the cost of parsing a format string outside of the format function
+  which can be beneficial when identically formatting many objects of the same
+  types. Thanks `@stryku (Mateusz Janek) <https://github.com/stryku>`_.

+* Implemented precision for floating-point durations
+  (`#1004 <https://github.com/fmtlib/fmt/issues/1004>`_,
+  `#1012 <https://github.com/fmtlib/fmt/pull/1012>`_):

+  .. code:: c++
+
+     auto s = fmt::format("{:.1}", std::chrono::duration<double>(1.234));
+     // s == 1.2s
+
+  Thanks `@DanielaE (Daniela Engert) <https://github.com/DanielaE>`_.
+
+* Implemented ``chrono`` format specifiers ``%Q`` and ``%q`` that give the value
+  and the unit respectively (`#1019 <https://github.com/fmtlib/fmt/pull/1019>`_):
+
+  auto value = fmt::format("{:%Q}", 42s); // value == "42"
