Claude Code 2.1.274 fixes six MCP failure modes that silently break production tool sessions, adds store.connect_timeout_seconds and CLAUDE_CODE_GATEWAY_DRAIN_TIMEOUT_MS to the Claude apps gateway, and makes corrupted transcripts self-heal instead of looping forever.
2.1.265 silently broke all gateway and proxy setups that had CLAUDE_CODE_USE_GATEWAY set alongside an API key or custom auth. Here's the exact affected configuration, the error, and what the release adds for gateway operators.
Claude Code 2.1.203 fixes a critical background-agent bug that silently dropped ANTHROPIC_BASE_URL, sending API keys to Anthropic's default endpoint and failing with 401. Any team routing Claude Code through a custom AI gateway must audit and upgrade.
Claude Code 2.1.199 fixes five operator-critical issues: TLS proxy errors fail fast with guidance, subagent silent successes become real errors, retry watchdog jumps to 300, a Linux daemon kill-loop is patched, and SendMessage guards against name mismatch.
DashScope workspace endpoint routing turns Alibaba Cloud Model Studio base URLs into an operator decision across regions, SDKs, fallback policy, and reliability evidence.
GitHub availability dropped to 88.4% in June as AI coding agents drove commit volume 14× year-over-year. Microsoft confirmed routing traffic through AWS — a decision that redefines what multi-cloud means for your CI/CD pipeline.
