I am working on a quality assurance system where some procedures might be in a state where they haven't yet been released because they are currently being worked on. They may have also been a previous release of the document, and the document I am trying to describe is the one with changes to the previous release.
An analogy might be how you would refer to Mac OSX 10.8 Mountain Lion - it isn't yet released, because it is still being worked on.
I have been calling it
unreleased but this to me sounds awkward and doesn't really describe the state.
Is there a word that I'm overlooking that describes this?
