Rust toolchain updated to v0.126.0-alpha.13.
Shell cancellations now finish cleanly, and tool streaming defaults adjusted for non-Anthropic models to reduce rejected tool calls.
**Claude Code** adds `ANTHROPIC_BEDROCK_SERVICE_TIER` environment variable to switch Bedrock tiers and enables `/resume` to find sessions by pasted PR URL.
Press `ctrl+x` then `b` to background running tasks, plus improved `/remote` status hints and session picker UX.
Preview version bump to v1.1.1-pre with no documented changes.
No material changes for developers.
