v0.10.5 — Claude Sonnet 5

Features

Claude Sonnet 5 now available — Anthropic's newest Sonnet-class model (claude-sonnet-5, released 2026-06-30) is now selectable in the model picker, with a 1M-token context window and adaptive thinking. It joins the lineup as the primary Sonnet, with Sonnet 4.6 kept available as the previous generation. Bedrock routing (US / EU / Global inference profiles) and connection defaults are wired up so it works across both Anthropic and Amazon Bedrock connections. The default model is unchanged (Opus 4.8).

Claude Agent SDK uplifted to 0.3.197 — the bundled SDK moves from 0.3.170 to 0.3.197 (Claude Code v2.1.197 parity), so the bundled CLI is itself aware of Sonnet 5 (the sonnet alias, context-window, and effort defaults). Includes upstream fixes since 0.3.170, including a Windows CLI subprocess console-flash fix. Full typecheck and shared test suites pass clean. (5bf361b6)
