Recently shipped an undici 7 upgrade that drops Node 18, and improved query prompts across Context7 tools.

b1t setup now writes API key as standard Authorization header. The b1t CLI changed its header from a custom CONTEXT7_API_KEY to Authorization: Bearer <key>, fixing Codex auth failures where a custom header name caused it to fall through to a dead OAuth refresh token. Existing configs continue working — the hosted endpoint accepts both header forms.

ctx7 setup reliability improved. ctx7 reads the GitHub CLI auth token by invoking gh directly, avoiding shell wrappers that triggered Microsoft Defender for Endpoint alerts. Skill install now falls back to raw.githubusercontent.com when the API is blocked.

Better error messages across the board. ctx7 OAuth failures now report the actual cause (TLS interception, DNS, firewall, timeout) or the HTTP status and body excerpt. The MCP server also skips loopback, link-local, and CGNAT addresses when extracting the client IP from X-Forwarded-For, so proxy-internal hops no longer pollute the reported IP.

query-docs asks for one concept per query. Callers are told to make a separate query per distinct topic unless the question is about interactions, avoiding diluted results. Applied across MCP, CLI, pi, and AI SDK tools.

Workflow runs gained multi-label support. The label field accepts string | string[], and context.labels replaces the deprecated context.label.
