I was looking through the Unity Software Additional Terms and found something interesting in Section 1.5 for users of Unity Pro:
This appears to be an offering that’s distinct from Unity Build Server. However, I can’t find any public information about the Unity Build License subscription; where can I find out more information about it?
No, it’s all part of the same thing. The wording is maybe a little confusing - I’ve pinged legal to see if they can get it clarified - but the Build License subscriptions that the terms are referring to are the individual ‘seats’ you buy in your Unity Build Server subscription.
My apologies - it seems I had this wrong, and you were right in your first post.
“Build License” is the old product, the precursor to Unity Build Server. It was only ever available to Enterprise customers through direct sales channels - that’s why you don’t see public mention of it - and now that Unity Build Server is available, Build License is no longer available to new customers.
