2.1.101 — Claude code - Product release notes & changelog tool

Added /team-onboarding command to generate a teammate ramp-up guide from your local Claude Code usage
Added OS CA certificate store trust by default, so enterprise TLS proxies work without extra setup (set CLAUDE_CODE_CERT_STORE=bundled to use only bundled CAs)
/ultraplan and other remote-session features now auto-create a default cloud environment instead of requiring web setup first
Improved brief mode to retry once when Claude responds with plain text instead of a structured message
Improved focus mode: Claude now writes more self-contained summaries since it knows you only see its final message
Improved tool-not-available errors to explain why and how to proceed when the model calls a tool that exists but isn’t available in the current context
Improved rate-limit retry messages to show which limit was hit and when it resets instead of an opaque seconds countdown
Improved refusal error messages to include the API-provided explanation when available
Improved claude -p --resume <name> to accept session titles set via /rename or --name
Improved settings resilience: an unrecognized hook event name in settings.json no longer causes the entire file to be ignored
Improved plugin hooks from plugins force-enabled by managed settings to run when allowManagedHooksOnly is set
Improved /plugin and claude plugin update to show a warning when the marketplace could not be refreshed, instead of silently reporting a stale version
Improved plan mode to hide the “Refine with Ultraplan” option when the user’s org or auth setup can’t reach Claude Code on the web
Improved beta tracing to honor OTEL_LOG_USER_PROMPTS, OTEL_LOG_TOOL_DETAILS, and OTEL_LOG_TOOL_CONTENT; sensitive span attributes are no longer emitted unless opted in
Improved SDK query() to clean up subprocess and temp files when consumers break from for await or use await using
Fixed a command injection vulnerability in the POSIX which fallback used by LSP binary detection
Fixed a memory leak where long sessions retained dozens of historical copies of the message list in the virtual scroller
Fixed --resume/--continue losing conversation context on large sessions when the loader anchored on a dead-end branch instead of the live conversation
Fixed --resume chain recovery bridging into an unrelated subagent conversation when a subagent message landed near a main-chain write gap
Fixed a crash on --resume when a persisted Edit/Write tool result was missing its file_path
Fixed a hardcoded 5-minute request timeout that aborted slow backends (local LLMs, extended thinking, slow gateways) regardless of API_TIMEOUT_MS
Fixed permissions.deny rules not overriding a PreToolUse hook’s permissionDecision: "ask" — previously the hook could downgrade a deny into a prompt
Fixed --setting-sources without user causing background cleanup to ignore cleanupPeriodDays and delete conversation history older than 30 days
Fixed Bedrock SigV4 authentication failing with 403 when ANTHROPIC_AUTH_TOKEN, apiKeyHelper, or ANTHROPIC_CUSTOM_HEADERS set an Authorization header
Fixed claude -w <name> failing with “already exists” after a previous session’s worktree cleanup left a stale directory
Fixed subagents not inheriting MCP tools from dynamically-injected servers
Fixed sub-agents running in isolated worktrees being denied Read/Edit access to files inside their own worktree
Fixed sandboxed Bash commands failing with mktemp: No such file or directory after a fresh boot
Fixed claude mcp serve tool calls failing with “Tool execution failed” in MCP clients that validate outputSchema
Fixed RemoteTrigger tool’s run action sending an empty body and being rejected by the server
Fixed several /resume picker issues: narrow default view hiding sessions from other projects, unreachable preview on Windows Terminal, incorrect cwd in worktrees, session-not-found errors not surfacing in stderr, terminal title not being set, and resume hint overlapping the prompt input
Fixed Grep tool ENOENT when the embedded ripgrep binary path becomes stale (VS Code extension auto-update, macOS App Translocation); now falls back to system rg and self-heals mid-session
Fixed /btw writing a copy of the entire conversation to disk on every use
Fixed /context Free space and Messages breakdown disagreeing with the header percentage
Fixed several plugin issues: slash commands resolving to the wrong plugin with duplicate name: frontmatter, /plugin update failing with ENAMETOOLONG, Discover showing already-installed plugins, directory-source plugins loading from a stale version cache, and skills not honoring context: fork and agent frontmatter fields
Fixed the /mcp menu offering OAuth-specific actions for MCP servers configured with headersHelper; Reconnect is now offered instead to re-invoke the helper script
Fixed ctrl+], ctrl+\, and ctrl+^ keybindings not firing in terminals that send raw C0 control bytes (Terminal.app, default iTerm2, xterm)
Fixed /login OAuth URL rendering with padding that prevented clean mouse selection
Fixed rendering issues: flicker in non-fullscreen mode when content above the visible area changed, terminal scrollback being wiped during long sessions in non-fullscreen mode, and mouse-scroll escape sequences occasionally leaking into the prompt as text
Fixed crash when settings.json env values are numbers instead of strings
Fixed in-app settings writes (e.g. /add-dir --remember, /config) not refreshing the in-memory snapshot, preventing removed directories from being revoked mid-session
Fixed custom keybindings (~/.claude/keybindings.json) not loading on Bedrock, Vertex, and other third-party providers
Fixed claude --continue -p not correctly continuing sessions created by -p or the SDK
Fixed several Remote Control issues: worktrees removed on session crash, connection failures not persisting in the transcript, spurious “Disconnected” indicator in brief mode for local sessions, and /remote-control failing over SSH when only CLAUDE_CODE_ORGANIZATION_UUID is set
Fixed /insights sometimes omitting the report file link from its response
[VSCode] Fixed the file attachment below the chat input not clearing when the last editor tab is closed
