elementary OS Loki is the next version (0.4) of elementary OS and brings many new features like HiDPI support.The name is subject to change but it could be Loki or Thor. But when is it released , Ubuntu 16.04 will be released on April 21th 2016 so it must be some time after that.

I could not found much information on the internet

I know it is might be subject to change but Ubuntu has a release date

elementary OS releases are made on a task-based cycle and not a time-based cycle. Releases basically happen like this:

Currently, elementary OS releases are built from Ubuntu repositories. At the beginning of the cycle, we choose a target repository to work from. For Loki, that repo is Ubuntu 16.04.

We set up a daily repository where we build our source code against that target repository. Sometimes things build straight away and sometimes builds fail because of things like changing APIs. We find the causes of the build failures and update our source code until everything compiles.

The next step is generate daily disk images with our repository and the target (Ubuntu 16.04) repository. We do this using a system called metapackage "Seeds". It's the same way Ubuntu is built and it's documented in pretty fine detail here: https://docs.google.com/document/d/1RPPF14h1Sw2gQjGTuZjUIlNHnGrafS8ekhFjJM9MT00/edit

This is where the real work finally begins. We start compiling a list of all the things we want to get done into a big list of bugs and blueprints that we call a "milestone". Many of these things are reported and requested to us by our users. So in this way, future releases of elementary OS are directly shaped by user feedback. The first milestone is called "Alpha 1". Alphas are unstable, internal releases for our development team to track their progress.

Depending on how we decide to do releases, we could have multiple alphas during this phase. There were some pretty big API breaks between Freya and Loki so we had a lot fewer individual package releases. We also made it a goal to reduce the time that this cycle would last since we got a lot of feedback that users wanted faster OS releases. So instead of having multiple Alpha milestones this cycle, we had just one.

We then created a milestone "Beta1" which would be the first public testing release of elementary OS. This release needs to represent a somewhat stable and feature complete product, so it needs to contain any serious known regressions or important features. When we release Beta1, it is for developers and testers to help us find any major regressions before we release the stable version of Loki (called GM or Grand Master). The Beta1 milestone represents a kind of "home stretch" where we wrap up big features and get the OS ready for translations, screenshots, and documentation.

Typically elementary OS has more than 1 beta as developers and testers help us find major issues that we might have missed in internal testing. Once we're confident we have a shippable product, there's one last milestone series: Release Candidate or "RC". This milestone is often very small, containing only a handful of minor cosmetic issues. It includes things like preparing our release notes and changing the wallpaper to the new default as well as switching from our unstable daily repository to our stable repository that only contains released software.

RC's often come out just days apart and are the last chance to find any last-minute show-stopping issues. Once an RC is released that the team is happy with, that ISO file gets promoted to "GM". We upload it to our CDN, make copies available to press, and set the release date for Loki.


elementary have a saying about release dates, and they are quite serious.

When it's ready.

elementary releases are targeted to features and bugs being fixed, rather than some arbitrary release date.

    So they don't have a release date?

According to: http://www.networkworld.com/article/3039009/open-source-tools/elementary-boss-watches-the-linux-distro-make-great-strides.html

Do you have a time frame that you're looking at for releasing the next version of elementary OS? Or are you going with the "we release when it's ready" approach?

Haha, always 'when it's ready' but definitely this year :)

  • All the answers say it is ready.This is also corrrect

So their motto is "when it's ready" but judging by the comments from the guys on the simply elementary podcast there is a pretty high chance it will be released this summer or fall. But there is always a possibility that they decide to do more extensive new development or they run into a bunch of bugs and it might not be till next spring. But most likely it will be within 7 months after the Ubuntu 16.04 release.


Bringing an end to uncertainties, yesterday(14/06/2016) elementary team has announced availability of elementary OS loki beta which is first development release for upcoming elementary 0.4. It means work is under progress and final release can be expected soon.



Loki was released the 9 September 2016.
