 * Optimized ``tm`` formatting
   (`#2602 <https://github.com/fmtlib/fmt/pull/2602>`_,

   `#2670 <https://github.com/fmtlib/fmt/issues/2670>`_
   `#2671 <https://github.com/fmtlib/fmt/pull/2671>`_).
+
+  Processing of some specifiers such as ``%z`` and ``%Y`` is now up to 10-20x
+  times faster::

   Thanks `@phprus (Vladislav Shchapov) <https://github.com/phprus>`_.
 
+* Implemented subsecond formatting for chrono durations
+  (`#2623 <https://github.com/fmtlib/fmt/pull/2623>`_).
+  For example (`godbolt <https://godbolt.org/z/es7vWTETe>`__):
+
+  .. code:: c++
+
+     #include <fmt/chrono.h>
+
+     int main() {
+       fmt::print("{:%S}", std::chrono::milliseconds(1234));
+     }
+
+  prints "01.234".
+
+  Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
+
+
+* Deprecated ``_format``, an undocumented UDL-based format API
+  (`#2646 <https://github.com/fmtlib/fmt/pull/2646>`_).
+  Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
+
 * Disabled a partially broken copy ctor for ``dynamic_format_arg_store`` and
   enabled a working move ctor
   (`#2664 <https://github.com/fmtlib/fmt/pull/2664>`_).
   Thanks `@lucpelletier <https://github.com/lucpelletier>`_.
 
+* Added UDL-based named argument support to compile-time format string checks
+  (`#2640 <https://github.com/fmtlib/fmt/issues/2640>`_,
+  `#2649 <https://github.com/fmtlib/fmt/pull/2649>`_).
+  For example (`godbolt <https://godbolt.org/z/ohGbbvonv>`__):
+
+  .. code:: c++
+
+     #include <fmt/format.h>
+
+     int main() {
+       using namespace fmt::literals;
+       fmt::print("{answer:s}", "answer"_a=42);
+     }
+
+  gives a compile-time error on compilers with C++20 ``consteval`` support
+  (gcc 10+, clang 11+) because ``d`` is not a valid format specifier for a
+  string.
+
+  Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
+
+* Made floating point precision overflow check work with exceptions disabled
+  (`#2647 <https://github.com/fmtlib/fmt/pull/2647>`_).
+  Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
+
+* Resolved lookup ambiguity with C++20 format-related functions due to ADL
+  (`#2639 <https://github.com/fmtlib/fmt/issues/2639>`_,
+  `#2641 <https://github.com/fmtlib/fmt/pull/2641>`_).
+  Thanks `@mkurdej (Marek Kurdej) <https://github.com/mkurdej>`_.
+
+* Removed unnecessary inline namespace qualification
+  (`#2642 <https://github.com/fmtlib/fmt/issues/2642>`_,
+  `#2643 <https://github.com/fmtlib/fmt/pull/2643>`_).
+  Thanks `@mkurdej (Marek Kurdej) <https://github.com/mkurdej>`_.
+
+* Improved documentation
+  (`#2676 <https://github.com/fmtlib/fmt/issues/2676>`_).
+
 * Improved build configuration
   (`#2650 <https://github.com/fmtlib/fmt/pull/2650>`_,
   `#2651 <https://github.com/fmtlib/fmt/pull/2651>`_,
   `#2663 <https://github.com/fmtlib/fmt/pull/2663>`_).
   Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
 
+* Fixed various warnings and compilation issues
+  (`#2627 <https://github.com/fmtlib/fmt/issues/2627>`_,
+  `#2630 <https://github.com/fmtlib/fmt/pull/2630>`_). Thanks
+  `@andrewcorrigan (Andrew Corrigan) <https://github.com/andrewcorrigan>`_.
