The first release candidate for GCC 15.1 is available from https://gcc.gnu.org/pub/gcc/snapshots/15.1.0-RC-20250418/ ftp://gcc.gnu.org/pub/gcc/snapshots/15.1.0-RC-20250418/
and shortly its mirrors. It has been generated from git commit r15-9556-g96171a5cc7b99cb6. I have so far bootstrapped and tested the release candidate on x86_64-linux. Please test it and report any issues to bugzilla. If all goes well, we'd like to release 15.1 on Friday, April 25th. Happy Easter!
