LibreNMS version 26.3.0 was released on March the 16th, 2026.
We want to thank every one of the 37 contributors to LibreNMS this month. Another fairly big release for us this month so a huge shout out to everyone who has been submitting pull requests - we’ve been working hard to review and merge them all but as you can see we still have quite a lot to review and merge in. Please do bear with us.
A big thank you to @murrant, @Jellyfrog, chris9951 and @eskyuu for their outstanding contributions this month. It’s amazing to see the community helping push LibreNMS forward.

Make sure you thank these contributors for their time and effort!
