Cargo is bringing back the new build-dir layout, and this time it's built to scale.
Cargo re-stabilized the build-dir layout v2 [1], rolling back the rollback after three fixes addressed the performance and scaling issues that forced it off nightly. The layout, tracked in cargo issue #15010, is back with mitigations from PRs #17191, #17168, and #17236. Meanwhile, nightly Cargo also enables `-Zembed-metadata=no` by default [2], cutting metadata from embedded rlibs for faster builds, though it's clearly still experimental. On the rust-lang/rust side, a 12-PR rollup merged [3] that includes new atomic volatile intrinsics and the `unspecified_from()` API for IP and socket addresses. Infra cleanup continues: rust-timer branches are gone [4], and jdno is out of the infra-ci rotation [5] since triagebot kept assigning him PRs he hasn't been reviewing. Docs.rs is dropping `releases.files` and `releases.archive_storage` [6], simplifying storage and removing file list generation. And the index added crates like `glimta` and `diversion` [7] [8]. Skip the lock file bumps [9] [10] - they're routine.
Action items
- → Test the re-stabilized build-dir layout v2 on nightly; report any regressions rust-lang/cargo [plan]
- → Monitor nightly Cargo's default -Zembed-metadata=no; watch for build script issues rust-lang/cargo [monitor]
- → Watch for docs.rs storage changes; verify your crate's docs still build rust-lang/docs.rs [monitor]
- → Ignore the lock file maintenance PRs; routine dependency refresh rust-lang/docs.rs [monitor]
