   As part of our commitment to reliability and security, LaunchDarkly will retire all API versions except 20240415 on December 31, 2026.

   After this date, all requests made to retired versions will stop working. To avoid disruption, customers must update integrations and workflows to use version 20240415 before the retirement date.

   We previously announced the end of life (EOL) for older versions as of April 30, 2025. They have remained available during a grace period, which will end on December 31, 2026

   Upgrading now ensures uninterrupted access and provides immediate improvements in performance and functionality.

   We recognize this may be a large undertaking, which is why we are providing extended notice. If you need guidance, please reach out to your account team or contact our support team.

Impact, status and times are the vendor’s own, as last archived. View on stspg.io (opens in new tab).
