+
+8.1.0 - 2022-01-02
+------------------
+
+* Optimized chrono formatting

+
+  Thanks `@phprus (Vladislav Shchapov) <https://github.com/phprus>`_ and
+  `@toughengineer (Pavel Novikov) <https://github.com/toughengineer>`_.
+
+* 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 `@matrackif <https://github.com/matrackif>`_.
+
+* Fixed handling of precision 0 when formatting chrono durations
+  (`#2587 <https://github.com/fmtlib/fmt/issues/2587>`_,
+  `#2588 <https://github.com/fmtlib/fmt/pull/2588>`_).
+  Thanks `@lukester1975 <https://github.com/lukester1975>`_.
+
+* Fixed an overflow on invalid inputs in the ``tm`` formatter
+  (`#2564 <https://github.com/fmtlib/fmt/pull/2564>`_).
+  Thanks `@phprus (Vladislav Shchapov) <https://github.com/phprus>`_.
+
+* 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
+  (`#2394 <https://github.com/fmtlib/fmt/pull/2394>`_):
+
+  https://user-images.githubusercontent.com/576385/147710227-c68f5317-f8fa-42c3-9123-7c4ba3c398cb.mp4
+
+  Thanks `@benit8 (Benoît Lormeau) <https://github.com/benit8>`_ and
+  `@data-man (Dmitry Atamanov) <https://github.com/data-man>`_.
+
+* Added experimental support for compile-time floating point formatting
+  (`#2426 <https://github.com/fmtlib/fmt/pull/2426>`_,
+  `#2470 <https://github.com/fmtlib/fmt/pull/2470>`_).
+  It is currently limited to the header-only mode.
+  Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
+
+* 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`` and non-type
+  template parameter support (gcc 10+) because ``s`` is not a valid format
+  specifier for an integer.
+
+  Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
+
+* 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
+  (`#2549 <https://github.com/fmtlib/fmt/pull/2549>`_).
+  Thanks `@BRevzin (Barry Revzin) <https://github.com/BRevzin>`_.
+
+* 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
+  (`#1841 <https://github.com/fmtlib/fmt/pull/1841>`_).
+
+* Deprecated implicit conversion of ``[const] signed char*`` and 
+  ``[const] unsigned char*`` to C strings.
+
+* Deprecated ``_format``, a legacy UDL-based format API
+  (`#2646 <https://github.com/fmtlib/fmt/pull/2646>`_).
+  Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
+
+* Marked ``format``, ``formatted_size`` and ``to_string`` as ``[[nodiscard]]``
+  (`#2612 <https://github.com/fmtlib/fmt/pull/2612>`_).
+  `@0x8000-0000 (Florin Iucha) <https://github.com/0x8000-0000>`_.
+
+* Added missing diagnostic when trying to format function and member pointers
+  as well as objects convertible to pointers which is explicitly disallowed
+  (`#2598 <https://github.com/fmtlib/fmt/issues/2598>`_,
+  `#2609 <https://github.com/fmtlib/fmt/pull/2609>`_,
+  `#2610 <https://github.com/fmtlib/fmt/pull/2610>`_).
+  Thanks `@AlexGuteniev (Alex Guteniev) <https://github.com/AlexGuteniev>`_.
+
+* Optimized writing to a contiguous buffer with ``format_to_n``
+  (`#2489 <https://github.com/fmtlib/fmt/pull/2489>`_).
+  Thanks `@Roman-Koshelev <https://github.com/Roman-Koshelev>`_.
+
+* Optimized writing to non-``char`` buffers
+  (`#2477 <https://github.com/fmtlib/fmt/pull/2477>`_).
+  Thanks `@Roman-Koshelev <https://github.com/Roman-Koshelev>`_.
+
+* Decimal point is now localized when using the ``L`` specifier.
+
+* Improved floating point formatter implementation
+  (`#2498 <https://github.com/fmtlib/fmt/pull/2498>`_,
+  `#2499 <https://github.com/fmtlib/fmt/pull/2499>`_).
+  Thanks `@Roman-Koshelev <https://github.com/Roman-Koshelev>`_.
+
+* Fixed handling of very large precision in fixed format
+  (`#2616 <https://github.com/fmtlib/fmt/pull/2616>`_).
+
+* Made a table of cached powers used in FP formatting static
+  (`#2509 <https://github.com/fmtlib/fmt/pull/2509>`_).
+  Thanks `@jk-jeon (Junekey Jeon) <https://github.com/jk-jeon>`_.
+
+* Resolved a 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>`_.
+
+* Implemented argument forwarding in ``format_to_n``
+  (`#2462 <https://github.com/fmtlib/fmt/issues/2462>`_,
+  `#2463 <https://github.com/fmtlib/fmt/pull/2463>`_).
+  Thanks `@owent (WenTao Ou) <https://github.com/owent>`_.
+
+* Fixed handling of implicit conversions in ``fmt::to_string`` and format string
+  compilation (`#2565 <https://github.com/fmtlib/fmt/issues/2565>`_).
+
+* Changed the default access mode of files created by ``fmt::output_file`` to
+  ``-rw-r--r--`` for consistency with ``fopen``
+  (`#2530 <https://github.com/fmtlib/fmt/issues/2530>`_).
+
+* Make ``fmt::ostream::flush`` public
+  (`#2435 <https://github.com/fmtlib/fmt/issues/2435>`_).
+
+* Improved C++14/17 attribute detection
+  (`#2615 <https://github.com/fmtlib/fmt/pull/2615>`_).
+  Thanks `@AlexGuteniev (Alex Guteniev) <https://github.com/AlexGuteniev>`_.
+
+* Improved ``consteval`` detection for MSVC
+  (`#2559 <https://github.com/fmtlib/fmt/pull/2559>`_).
+  Thanks `@DanielaE (Daniela Engert) <https://github.com/DanielaE>`_.

+# Bazel support
+
+To get [Bazel](https://bazel.build/) working with {fmt} you can copy the files `BUILD.bazel`, `WORKSPACE.bazel`, `.bazelrc`, and `.bazelversion` from this folder (`support/bazel`) to the root folder of this project. This way {fmt} gets bazelized and can be used with Bazel (e.g. doing a `bazel build //...` on {fmt}). 
+
+## Using {fmt} as a dependency
+
+The following minimal example shows how to use {fmt} as a dependency within a Bazel project.
+
+The following file structure is assumed:
+
+```
+example
+├── BUILD.bazel
+├── main.cpp
+└── WORKSPACE.bazel
+```
+
+*main.cpp*:
+
+```c++
+#include "fmt/core.h"
+
+int main() {
+  fmt::print("The answer is {}\n", 42);
+}
+```
+
+The expected output of this example is `The answer is 42`.
+
+*WORKSPACE.bazel*:
+
+```python
+load("@bazel_tools//tools/build_defs/repo:git.bzl", "git_repository")

+
+In the *WORKSPACE* file, the {fmt} GitHub repository is fetched. Using the attribute `patch_cmds` the  files `BUILD.bazel`, `WORKSPACE.bazel`, `.bazelrc`, and `.bazelversion` are moved to the root of the {fmt} repository. This way the {fmt} repository is recognized as a bazelized workspace. 
+
+*BUILD.bazel*:
+
+```python
+cc_binary(
+    name = "Demo",
+    srcs = ["main.cpp"],
+    deps = ["@fmt"],
+)
+```
+
+The *BUILD* file defines a binary named `Demo` that has a dependency to {fmt}.
+
+To execute the binary you can run `bazel run //:Demo`.
