The Rust compiler just got smarter about skipping expensive test suites and cleaner macro parsing internals, while the ecosystem welcomed a fresh batch of new crates.

Bootstrap can now intelligently skip the coverage test suite without forcing users to enumerate every path they didn't request [1]. This solves a long-standing friction point where running `./x test --skip=te` would still burn cycles on coverage instrumentation. In parallel, macro parsing landed significant preparatory work for a BFS-to-DFS conversion [2], clearing technical debt and setting up simpler code paths that the team has been building toward. The stdlib integration continued its cleanup pace: compiletest dumped its local VecDeque compatibility shim in favor of the now-stable `pop_front_if` method [3], keeping the codebase tighter and more modern. The compiler's diagnostics module naming got another pass [4], continuing the systematic errors.rs-to-diagnostics.rs rename campaign [5]. Meanwhile, const scalar pair offset handling got a critical fix [5] and AArch64 ILP32 builds are no longer stumbling on 128-bit integer cfgs. On the crates.io side, mockforge-chaos, wince, hpvca, xei-editor, and ssmtui all shipped updates [6][7][8][9][10].
