- Stabilized new language and const‑eval features (if‑let guards, inline PowerPC asm, consistent padding semantics, many const APIs, and path‑segment keyword imports) and added neon‑accelerated `str::contains` for AArch64.
- Updated compiler security with patches for CVE‑2026‑6042 and CVE‑2026‑40200, promoted several Apple and PowerPC platforms to Tier 2, and upgraded to LLVM 22.
- Introduced breaking changes: stricter `$crate` imports, altered const‑promotion and pattern‑matching semantics, deprecation of `Eq::assert`, and new compatibility warnings for ambiguous imports and unsafe match ergonomics.
