Rust's random module just got smarter: Lemire's algorithm now powers bounded sampling in RangeInclusive, while a new semver compatibility test ensures the standard library stays API-stable.

The core team shipped bounded random sampling [1] using Lemire's algorithm, the same approach FreeBSD uses for arc4random_uniform. This lands a long-requested Distribution trait for RangeInclusive, preventing the typo errors that plague unconstrained range sampling. In parallel, stdlib gains automated semver checking [2] via cargo-semver-checks, executed through a new `x test std-semver-check` command in bootstrap. The implementation aims to catch API breaks before they land on users. Triagebot got a data refresh [3] removing the allowed_merge_apps field from team configs, and fixed a race condition [4] between community review label removal and assignee updates. Over 77 commits across the stack this cycle, with the Cargo team consolidating tooling [5] by importing cargo-tracker and cargo-meetings as Cargo scripts for internal use.

Action items

→ Review bounded sampling implementation for RangeInclusive performance characteristics in your code paths rust-lang/rust [plan]
→ Integrate stdlib semver checks into your CI workflows when available rust-lang/rust [monitor]
→ Update any local triagebot configurations to remove allowed_merge_apps field rust-lang/triagebot [plan]
