+## `warning-level=everything` option
+
+The new `everything` value for the built-in `warning_level` enables roughly all applicable compiler warnings.
+For clang and MSVC, this simply enables `-Weverything` or `/Wall`, respectively.
+For GCC, meson enables warnings approximately equivalent to `-Weverything` from clang.
