UniFi Controller Releases [Updated Jun 27th, 2018]

[ Edited ]

I'm excited to announce that we're shortening our release cycle to speed up the process of getting new features to you. With that, I'd like to introduce the 5.8 Stable branch alongside the Long-Term Support (LTS) 5.6 branch.


I would like to share an overview of our release structure as well as highlight some of the new features introduced in the UniFi SDN controller branches.



Releases Structure


  • We will only post Stable Candidate (SC) and Stable releases in the public UniFi sections. Each release will first be posted as a Stable Candidate. More on that HERE (
  • Each Stable Candidate is preceded by many Testing releases which are published to Alpha and Beta channels. We make sure that we fix critical issues at an early step.
  • We collect all feedback from you at each step of a release cycle, we track issues and suggestions, and schedule improvements internally.
  • We test all releases internally using automated processes to cover as many as possible test cases.



Current Releases


We are constantly making improvements across all of our current Stable, Stable Candidate, and Testing release branches:
