Uptime Kuma 2.4.0 released on 31-05-2026
Uptime Kuma 2.4.0 is out now. Self-hosters and ops teams get new notification providers, RSS incident entries for status syndication, and improvements to monitor authentication and protocols.
Visit the Uptime Kuma GitHub release notes for full details and upgrade instructions.
What’s in this release
- New notification integrations: EgoSMS SMS provider for Uganda and a VKTeams bot; incidents are now included in the RSS feed for syndication.
- Monitor authentication and protocol improvements: optional token field for gamedig monitors and bearer token support (including WebSocket upgrade monitors), plus an updated documentation link for API key usage.
- Bug fixes and repository/dev tooling tweaks: fixes for npm 11.16.0 handling, NTLM monitor failures over plain HTTP (400 errors), normalised hidden log level lookup, dev data directory handling for non-master branches, and a large set of translation updates from Weblate.
Upgrade notes
- Security: an authenticated/admin-only Remote Code Execution vulnerability in an upstream dependency has been addressed; maintainers will provide full disclosure later — contact the maintainer if you need immediate information.
- Ignore the Docker-only Let’s Encrypt Gen Y root certificate change that appeared in the diff; the project asks users to disregard that alteration.
