Below is a “sanitized” version of the Daz Studio v4.x change log. This information is posted as part of a conscious effort to be more transparent in the development process. Not all information relating to a particular build is presented on this page - some information is still considered private and is therefore not included.

This is the channel where the “production ready” build is distributed to the general public.

This is the channel where the builds that are not considered “production ready” yet are provided for testing by the general public. This channel typically provides a build that is in the BETA phase of development, but technically can provide a build in the ALPHA phase.

This channel is similar to the Public Build channel, except that it is limited to a select group of individuals that serve as the “front line” or the “canary in a coal mine” for a time before the build is promoted to a less restricted channel. This channel is more likely to see an ALPHA build than the Public Build channel is.
