- `remote-test-server`'s `remote` argument has been removed in favor of the `--bind` flag. Use `--bind 0.0.0.0:12345` to replicate the behavior of the `remote` argument.
- `x.py fmt` now formats only files modified between the merge-base of HEAD and the last commit in the master branch of the rust-lang repository and the current working directory. To restore old behaviour, use `x.py fmt .`. The check mode is not affected by this change. [#105702](https://github.com/rust-lang/rust/pull/105702)
- The `llvm.version-check` config option has been removed. Older versions were never supported. If you still need to support older versions (e.g. you are applying custom patches), patch `check_llvm_version` in bootstrap to change the minimum version. [#108619](https://github.com/rust-lang/rust/pull/108619)
+- The `rust.ignore-git` option has been renamed to `rust.omit-git-hash`. [#110059](https://github.com/rust-lang/rust/pull/110059)
