When do Unity versions become available on Cloud Build?

Hi,

I'm just wondering when new Unity versions become available on Cloud Build? Are they added automatically or has someone approve them for Cloud Build?
As a recent example, 2019.1.7f1 is availabe since a few days but it's not on Cloud Build. Are there any issues wit it or does it just take time?

And while we're at it, when and which versions get removed? Do you have statistics which versions are used how often? Are they shareable?

Thanks,
Alex

 

It's a semi-manual process which does require manual approval and sometimes introduces new major issues. Generally we're going to be a bit slower to introduce new 2019.1 versions until the 2019.2f release since the majority of our customers are on 2019.1 and we want to catch any major bugs which are going to affect so many customers before release. We have quite a lot of plans for improving this process both on our end and in terms of external visibility but we're extremely busy on feature work and major infrastructure improvements at the moment so it might be a while before we can speed things up there.

Version removal is a long story. There's a lot of good reasons why we should only be supporting versions with the same lifecycle as Unity itself (with LTS release cycles and etc) however we recognize that enforcing that EOL cycle would be annoying for customers and also Unity only adopted that lifecycle pretty recently. Pre-5.5 versions were removed mostly because it was becoming increasingly, well, not actually possible to execute these versions of Unity. The 5.5 version removal is also the second time we've ever removed any versions in the time Cloud Build has been operating. We'll be improving our process as time moves on there but we don't currently have any concrete plans for regular version deletions.

 

Here's the LTS lifecycle details: https://blogs.unity3d.com/2018/04/0...g-the-tech-and-long-term-support-lts-streams/

Also we absolutely do not want to breach the LTS specifications i.e. 2017.4 releases will be available until 2020 at the earliest. Most likely we will also support earlier 2017 releases for the same time frame simply because the work required for 2017.4 will be sufficient to support e.g. 2017.1 but that's less guaranteed.

 

Thanks for the insights Victor.
