No, artifacts for the release are ready to go. We did discover a bug – https://github.com/rust-lang/rust/issues/59834 – but it’s not critical so we’re not halting or delaying the release because of it. If the macOS issue is fixed, we may be able to land the fix in time for 1.34, if not, then it’ll almost certainly be in 1.35 (or a point release, should one be issued).
