 ## Limitations
 
-For the compile time preprocessing of format strings non non-type template parameters are heavily relied upon,
-which means C++20 is required.
-
 Only a relatively limited subset of the `fmtlib` syntax is recognized (for now anyway). In particular,
-float formatting in decimal and integer formatting in decimal, binary and hexadecimal are supported.
+there is no support for positional arguments, alignment, chrono format specs and custom const_format specifications.
 
 By nature of the library design, which forces compile-time preprocessing of the const_format string, no dynamic width or
 dynamic precision can be implemented.
