Ecosystem Impact
MCP has appeared in 9 of the last 10 releases — the most consistently touched subsystem in recent history. VS Code, by contrast, last appeared 5 releases back (v2.1.86), a notable silence after sustained attention throughout mid-March.

May Help If You've Noticed
Subagents permanently fail to spawn after you kill or renumber tmux windows during a long session
Stop hooks fail unexpectedly even though your script returns the correct response
Plugin MCP servers show 'connecting' at startup and never finish initializing
Typing /vim does nothing and vim mode seems to have vanished
Scrolling up in iTerm2 or Ghostty shows duplicate messages or jumps unexpectedly

Changes in Claude Code v2.1.92

Added3 changes

  • •Added forceRemoteSettingsRefresh policy setting: when set, the CLI blocks startup until remote managed settings are freshly fetched, and exits if the fetch fails (fail-closed)
  • •Added interactive Bedrock setup wizard accessible from the login screen when selecting "3rd-party platform" — guides you through AWS authentication, region configuration, credential verification, and model pinning
  • •Added per-model and cache-hit breakdown to /cost for subscription users

Improved1 change

  • •Improved Write tool diff computation speed for large files (60% faster on files with tabs/&/$)

Fixed11 changes

  • •Fixed subagent spawning permanently failing with "Could not determine pane count" after tmux windows are killed or renumbered during a long-running session
  • •Fixed prompt-type Stop hooks incorrectly failing when the small fast model returns ok:false, and restored preventContinuation:true semantics for non-Stop prompt-type hooks
  • •Fixed tool input validation failures when streaming emits array/object fields as JSON-encoded strings
  • •Fixed an API 400 error that could occur when extended thinking produced a whitespace-only text block alongside real content
  • •Fixed accidental feedback survey submissions from auto-pilot keypresses and consecutive-prompt digit collisions
  • •Fixed misleading "esc to interrupt" hint appearing alongside "esc to clear" when a text selection exists in fullscreen mode during processing
  • •Fixed Homebrew install update prompts to use the cask's release channel (claude-code → stable, claude-code@latest → latest)
  • •Fixed ctrl+e jumping to the end of the next line when already at end of line in multiline prompts
  • •Fixed an issue where the same message could appear at two positions when scrolling up in fullscreen mode (iTerm2, Ghostty, and other terminals with DEC 2026 support)
  • •Fixed idle-return "/clear to save X tokens" hint showing cumulative session tokens instead of current context size
  • •Fixed plugin MCP servers stuck "connecting" on session start when they duplicate a claude.ai connector that is unauthenticated

Removed2 changes

  • •Removed /tag command
  • •Removed /vim command (toggle vim mode via /config → Editor mode)

Other4 changes

  • •/release-notes is now an interactive version picker
  • •Remote Control session names now use your hostname as the default prefix (e.g. myhost-graceful-unicorn), overridable with --remote-control-session-name-prefix
  • •Pro users now see a footer hint when returning to a session after the prompt cache has expired, showing roughly how many tokens the next turn will send uncached
  • •Linux sandbox now ships the apply-seccomp helper in both npm and native builds, restoring unix-socket blocking for sandboxed commands
