 # 10.2.0 - TBD
 
+-   Added a formatter for `std::bitset`
+    (https://github.com/fmtlib/fmt/pull/3660). For example
+    ([godbolt](https://godbolt.org/z/bdEaGeYxe)):
+
+    ```c++
+    #include <bitset>
+    #include <fmt/std.h>
+
+    int main() {
+      fmt::print("{}\n", std::bitset<6>(42)); // prints "101010"
+    }
+    ```
+
+    Thanks @muggenhor.
