The first release candidate for GCC 15.3 is available from https://gcc.gnu.org/pub/gcc/snapshots/15.3.0-RC-20260605/ ftp://gcc.gnu.org/pub/gcc/snapshots/15.3.0-RC-20260605/
and shortly its mirrors. It has been generated from git commit r15-11263-gbf0465b3e2c314. 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 15.3 on Friday, June 12th.
