Hello,

Many thanks (again) for the great work!

When will gfortran-15 be supported? As you know, it was released:

Thank you!

It's only published for homebrew so far. It should work on mac. It will start to work on linux when it's published for apt. We could install it directly I guess, but doing that every release is burdensome.

With #137 the latest gcc will become the default on each platform as soon as it becomes available in the relevant package manager. I'll try and make a new release and update the v1 tag soon, in the meantime you can switch to @main though it may be unstable
