Scheduled - We currently have no indication that LaunchDarkly-hosted services or customer data are impacted by the publicly-disclosed compromised intermediate CA certificates from eMudhra (https://emudhra.we-have-a-problem.com/). This guidance applies to all LaunchDarkly instances: Commercial, EU, and Federal.
LaunchDarkly has already taken precautionary steps to secure our platform and has released updated versions of the Relay Proxy and SDKs used by our customers. We continue to monitor the situation and patch all non-critical services.
We highly recommend that customers immediately take the following steps to secure the network connection between their systems and LaunchDarkly:
- Update LaunchDarkly SDKs and Relay Proxy listed below to the latest version provided
- Ensure your application hosts disallow the compromised CAs
- Follow publicly-documented remediation steps for your application infrastructure to disallow compromised CAs: https://emudhra.we-have-a-problem.com/

Planned Upcoming API Versions Retirement Dec 31, 2026 01:00-09:00 PST
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
For full details, see our API version changelog: https://launchdarkly.com/docs/api#api-version-changelog
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.
