Suggestions on Linux distro that allows updates ot C++ to latest compiler releases

I am currently using Ubuntu 24.04 (22.04. sorry, wrong) but frustrated that I can't load the latest GCC compilers. I have GCC 14.2 but want to install 14.3 and then 15.1 when available. Ubuntu won't let me install 15 because it isn't in the stable release. What distros allow updating the compilers? Will they use my existing home directory which is on a separate disk?
