 - Improved debug codegen.
 
+- Added an experimental `fmt::writer` API that can be used for writing to
+  different destinations such as files or strings
+  (https://github.com/fmtlib/fmt/issues/2354).
+  For example ([godbolt](https://www.godbolt.org/z/rWoKfbP7e)):
+
+  ```c++
+  #include <fmt/os.h>
+
+  void write_text(fmt::writer w) {
+    w.print("The answer is {}.", 42);
+  }
+
+  int main() {
+    // Write to FILE.
+    write_text(stdout);
+
+    // Write to fmt::ostream.
+    auto f = fmt::output_file("myfile");
+    write_text(f);
+
+    // Write to std::string.
+    auto sb = fmt::string_buffer();
+    write_text(sb);
+    std::string s = sb.str();
+  }
+  ```
