    fmtlib: updated to 8.1.1

    8.1.1 - 2022-01-06
    ------------------
    * Restored ABI compatibility with version 8.0.x
    * Fixed chorno formatting on big endian systems
    * Fixed a linkage error with mingw

    8.1.0 - 2022-01-02
    ------------------
    * Optimized chrono formatting
      Processing of some specifiers such as ``%z`` and ``%Y`` is now up to 10-20
      times faster, for example on GCC 11 with libstdc++::

        ----------------------------------------------------------------------------
        Benchmark                                  Before             After
        ----------------------------------------------------------------------------
        FMTFormatter_z                             261 ns             26.3 ns
        FMTFormatterCompile_z                      246 ns             11.6 ns
        FMTFormatter_Y                             263 ns             26.1 ns
        FMTFormatterCompile_Y                      244 ns             10.5 ns
        ----------------------------------------------------------------------------
    * Implemented subsecond formatting for chrono durations
      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".
    * Fixed handling of precision 0 when formatting chrono durations
    * Fixed an overflow on invalid inputs in the ``tm`` formatter
    * Added ``fmt::group_digits`` that formats integers with a non-localized digit
      separator (comma) for groups of three digits.
      For example (`godbolt <https://godbolt.org/z/TxGxG9Poq>`__):

      .. code:: c++

         #include <fmt/format.h>

         int main() {
           fmt::print("{} dollars", fmt::group_digits(1000000));
         }

      prints "1,000,000 dollars".

    * Added support for faint, conceal, reverse and blink text styles
    * Added experimental support for compile-time floating point formatting
      It is currently limited to the header-only mode.
    * Added UDL-based named argument support to compile-time format string checks
      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`` and non-type
      template parameter support (gcc 10+) because ``s`` is not a valid format
      specifier for an integer.
    * Implemented escaping of string range elements.
      For example (`godbolt <https://godbolt.org/z/rKvM1vKf3>`__):

      .. code:: c++

         #include <fmt/ranges.h>
         #include <vector>

         int main() {
           fmt::print("{}", std::vector<std::string>{"\naan"});
         }

      is now printed as::

        ["\naan"]

      instead of::

        ["
        aan"]

    * Switched to JSON-like representation of maps and sets for consistency with
      Python's ``str.format``.
      For example (`godbolt <https://godbolt.org/z/seKjoY9W5>`__):

      .. code:: c++

         #include <fmt/ranges.h>
         #include <map>

         int main() {
           fmt::print("{}", std::map<std::string, int>{{"answer", 42}});
         }

      is now printed as::

        {"answer": 42}

    * Extended ``fmt::join`` to support C++20-only ranges
    * Optimized handling of non-const-iterable ranges and implemented initial
      support for non-const-formattable types.
    * Disabled implicit conversions of scoped enums to integers that was
      accidentally introduced in earlier versions
    * Deprecated implicit conversion of ``[const] signed char*`` and
      ``[const] unsigned char*`` to C strings.
    * Deprecated ``_format``, a legacy UDL-based format API
    * Marked ``format``, ``formatted_size`` and ``to_string`` as ``[[nodiscard]]``
    * Added missing diagnostic when trying to format function and member pointers
      as well as objects convertible to pointers which is explicitly disallowed
    * Optimized writing to a contiguous buffer with ``format_to_n``
    * Optimized writing to non-``char`` buffers
    * Decimal point is now localized when using the ``L`` specifier.
    * Improved floating point formatter implementation
    * Fixed handling of very large precision in fixed format
    * Made a table of cached powers used in FP formatting static
    * Resolved a lookup ambiguity with C++20 format-related functions due to ADL
    * Removed unnecessary inline namespace qualification
    * Implemented argument forwarding in ``format_to_n``
    * Fixed handling of implicit conversions in ``fmt::to_string`` and format string
      compilation
    * Changed the default access mode of files created by ``fmt::output_file`` to
      ``-rw-r--r--`` for consistency with ``fopen``
    * Make ``fmt::ostream::flush`` public
    * Improved C++14/17 attribute detection
    * Improved documentation
    * Improved fuzzers and added a fuzzer for chrono timepoint formatting
    * Added the ``FMT_SYSTEM_HEADERS`` CMake option setting which marks {fmt}'s
      headers as system. It can be used to suppress warnings
    * Added the Bazel build system support
    * Improved build configuration and tests
    * Fixed various warnings and compilation issues
