Seven new dependencies — permalink

We added axios-cookiejar-support, csv-parse, imapflow, mysql2, pdf-parse, tough-cookie, and winston to the runtime, covering persistent cookie handling, CSV parsing, IMAP inbox monitoring, a modern MySQL client, PDF text extraction, and structured logging. We also removed jsdom; for DOM interactions, use Playwright's built-in Page APIs instead.

Also shipped — permalink

Private Locations: Runtime 2026.04 is available on Checkly Agent 7.0.0, which ships with VM2 3.10.5 for tighter security; update your agent to 7.0.0 or later to unlock this runtime.
Performance: The updated VM2 security layer adds stricter sandboxing, so Browser checks may run slower compared to previous runtime versions; improvements are planned in upcoming releases.
