Rust's interpreter pulled a major upstream sync while the compiler team shipped a query optimization that bypasses redundant work during incremental compilation.

Miri pulled in the latest changes from rust-lang/rust via Josh, absorbing recent compiler fixes and improvements [1]. Meanwhile, the compiler landed a targeted optimization that skips the full query machinery when promoting disk-cached values into memory at the end of incremental sessions [2], cutting unnecessary overhead in rebuild profiles. On the team side, the Cargo leadership transitioned: Eric Huss stepped down and moved to alumni status, with Jacob and Weihang now leading the team [3]. The rust-lang/team repo added automation to identify inactive contributors and move them to alumni status according to the new membership policy [4]. Across the ecosystem, thinvec got bumped to 0.2.19 with a gated `may_dangle` Drop impl, unlocking its use in more TCX reference-holding types [5].

Action items

→ Review incremental build performance locally if you maintain cache-heavy projects rust-lang/rust [monitor]
→ Update thinvec dependency to 0.2.19 for better arena code compatibility rust-lang/rust [plan]
