Claude Code 2.1.92: Bedrock Setup, Cost Breakdown

TL;DR

• Interactive Bedrock setup wizard for AWS authentication and model configuration
• Per-model cost breakdown and cache-hit stats for Pro users
• Fixed subagent spawning failures and prompt cache expiry hints

New

• Bedrock setup wizard — Interactive guide from login screen for AWS authentication, region config, and model pinning.
• Per-model cost breakdown — `/cost` now shows model-level and cache-hit breakdown for subscription users.
• Interactive release notes — `/release-notes` is now a version picker instead of static output.
• Remote Control session naming — Sessions now default to hostname prefix (e.g. `myhost-graceful-unicorn`), configurable with `--remote-control-session-name-prefix`.
• Cache expiry hints — Pro users see footer hint when returning to a session after prompt cache expires, showing uncached token count for next turn.
• forceRemoteSettingsRefresh policy — CLI blocks startup until remote managed settings are freshly fetched; exits if fetch fails (fail-closed).

Fixed

• Subagent spawning permanently failing with "Could not determine pane count" after tmux windows are killed or renumbered.
• Prompt-type Stop hooks incorrectly failing when small fast model returns `ok:false`.
• Tool input validation failures when streaming emits array/object fields as JSON-encoded strings.
• API 400 error when extended thinking produced whitespace-only text blocks alongside real content.
• Accidental feedback survey submissions from auto-pilot keypresses and consecutive-prompt digit collisions.
• Misleading "esc to interrupt" hint appearing with "esc to clear" during fullscreen text selection.
• Homebrew install update prompts now use correct cask release channel (`claude-code` → stable, `claude-code@latest` → latest).
• `ctrl+e` jumping to next line when already at end of line in multiline prompts.
• Duplicate message appearing at two positions when scrolling up in fullscreen mode (iTerm2, Ghostty, DEC 2026 terminals).
• Idle-return "/clear to save X tokens" hint showing cumulative session tokens instead of current context size.
• Plugin MCP servers stuck "connecting" on session start when duplicating unauthenticated claude.ai connector.
• Write tool diff computation speed improved 60% faster on files with tabs, `&`, or `$` characters.

Removed

• `/tag` command — removed.
• `/vim` command — toggle vim mode via `/config` → Editor mode instead.

Other

• Linux sandbox now ships `apply-seccomp` helper in both npm and native builds, restoring unix-socket blocking for sandboxed commands.

Update via Homebrew: brew upgrade claude-code
