bootstrap major change detection implementation The use of `changelog-seen` and `bootstrap/CHANGELOG.md` has not been functional in any way for many years. We often do major/breaking changes but never update the changelog file or the `changelog-seen`. This is an alternative method for tracking major or breaking changes and informing developers when such changes occur. Example output when bootstrap detects a major change:  |
||
|---|---|---|
| .. | ||
| cargo-clif.rs | ||
| filter_profile.rs | ||
| Readme.md | ||
| rustc-clif.rs | ||
| rustdoc-clif.rs | ||
| rustup.sh | ||
| setup_rust_fork.sh | ||
| test_bootstrap.sh | ||
| test_rustc_tests.sh | ||
This directory is for scripts that are either never directly invoked or are not used very often. Scripts that are frequently used should be kept at the project root.
