Hi,
Just a small clarification: print is not a C++ keyword. std::print was introduced in C++23 as a standard library function (from the <print> header), so technically Code::Blocks' syntax highlighter should not treat print as a language keyword.
The same applies to many names from the standard library (vector, string, format, etc.). Adding them manually to the keyword list may give the desired visual result, but they are not C++ keywords.
If there are actual C++ keywords missing from the current Code::Blocks list (especially keywords introduced in newer C++ standards), it would be useful to list those specifically. Those would make sense to add to the default syntax-highlighting configuration.
Regarding Fedora packages and release frequency, distro package versions are generally a separate issue from Code::Blocks nightly builds. Nightlies are development snapshots, while distributions usually package stable releases according to their own update policies.
