Claude Code adds an EndConversation tool for abusive users, a progress heartbeat for long tool calls, and various telemetry attributes.

READY TO POST:

anthropic's claude code is getting an endconversation tool, probably for handling those tricky jailbreak attempts. sounds like a useful safety net!

big claude code update: they've added a progress heartbeat for long-running tool calls and expanded opentelemetry logging. good for visibility and debugging.

[MERGED across 3 sources: github_releases, pages] shared signal: claude-code --- github_releases :: anthropics/claude-code --- anthropics/claude-code release: v2.1.214 name: v2.1.214 published: 2026-07-18T01:20:30Z url: https://github.com/anthropics/claude-code/releases/tag/v2.1.214 ## What's changed - Fixed single-segment `dir/**` allow rules like `Edit(src/**)` auto-approving writes to nested `dir/` directories anywhere in the tree instead of only `<cwd>/dir` - Fixed a permission-check bypass affecting commands run in Windows PowerShell 5.1 sessions - Fixed Bash permission checks to fail closed on file-descriptor redirect forms that bash parses differently than the permission analyzer - Fixed Bash permission checks misjudging very long commands — commands over 10,000 characters now always prompt instead of running automatically - Fixed Bash permission checks treating zsh variable subscripts and modifiers in `[[ ]]` comparisons as inert text — these commands now prompt for approval - Fixed Bash permission checks to no longer auto-approve certain `help` and `man` commands that could run unsafe options, command substitutions, or backslash paths - Fixed permission prompts on remote sessions that could proceed before the local confirmation dialog - Added the EndConversation tool: Claude can end sessions with highly abusive users or jailbreak attempts, as on claude.ai since 2025 — see https://www.anthropic.com/research/end-subset-conversations - Added a periodic progress heartbeat for long-running tool calls that previously went silent - Added an ISO `modified` timestamp to memory file frontmatter - Added `message.uuid`, `client_request_id`, and `tool_source` attributes to OpenTelemetry log events for message-level correlation and tool provenance - Added `CLAUDE_CODE_OTEL_CONTENT_MAX_LENGTH` to configure the 60 KB truncation limit on OpenTelemetry content attributes - Added reasoning effort to the `subagentStatusLine` payload, so custom agent rows can render model an
