The first release candidate for GCC 10.5 is available from https://gcc.gnu.org/pub/gcc/snapshots/10.5.0-RC-20230630/
and shortly its mirrors. It has been generated from git commit r10-11483-g8c12c47d0c5c40. I have so far bootstrapped and tested the release candidate on x86_64-linux. Please test it and report any issues to bugzilla. Note this will be the last release from the GCC 10 branch. If all goes well, we'd like to release 10.5 and close the branch on Friday, July 7th.
