Rust's own infrastructure is moving to Datadog provider v4, while a key maintainer's access is being cut, signaling a period of tightening security and modernizing tooling.

The Rust project's infrastructure team is consolidating its monitoring stack: the Datadog Terraform provider is being updated to v4 [1], with a separate migration of the AWS integration already staged on v3 [2]. This move is carefully staged; the v4 provider removes certain resources that required migration first, as noted in the upgrade guide [2]. Meanwhile, simpleinfra is pruning access: Eric Huss is moving to alumni status and his AWS access is being removed [3], a clear sign of least-privilege discipline. In the compiler, a rollup of five pull requests landed [4], including a revert of a previous merge and a fix to const eval normalization, plus a rustc-dev-guide subtree update [5] that keeps contributor docs current. Over in Miri, the interpreter gained source stepping commands for the CLI and DAP [6], and maintained RalfJung and team removed obsolete x86 intrinsics that stdarch no longer uses [7], as the codebase streamlines. And finally, crates.io-index saw five automated crate updates, all from bors, keeping the index fresh [8][9][10][11][12].

Action items

→ Review and merge the Datadog provider v4 update before the next simpleinfra apply rust-lang/simpleinfra [plan]
→ Monitor the Miri source-stepping changes for CLI and DAP integration regressions rust-lang/miri [monitor]
→ Check that the rollup revert in rust-lang/rust does not affect your nightly builds rust-lang/rust [monitor]
