 8.0.0 - TBD
 -----------
 
+* Enabled compile-time check by default. For example
+
+  .. code:: c++
+
+     #include <fmt/core.h>
+
+     int main() {
+       fmt::print("{:d}", "I am not a number");
+     }
+
+  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.
