🚀 Anthropic Official
Claude Code v2.1.121
Releases April 28 at 00:31 UTC with critical memory fixes: resolves unbounded multi-GB growth when processing images and a ~2 GB /usage memory leak. New capabilities include an alwaysLoad MCP server config option (tools skip deferral), a claude plugin prune command, type-to-filter search in /skills, PostToolUse output replacement for all tools, scrollable dialogs, /terminal-setup for iTerm2 clipboard, MCP server auto-retry (up to 3×), Vertex AI X.509 mTLS Workload Identity support, and OpenTelemetry stop_reason/finish_reasons spans. Also fixes --resume crashes, NO_PROXY non-compliance, Bash startup-dir deletion failures, and reduces peak file descriptor usage.
