I hear "Roll" as a verb in different sentences. The meanings that I find in dictionaries do not fully explain the exact meaning in those sentences.
For instance, in the following sentence : "We will be rolling the new feature by the end of week."
What is the exact meaning of "rolling"?
PS: Seems like "roll" in this sentence is actually "roll out". The new question is : Is it so common to omit "out" and just say "roll" instead of "roll out"?
Most likely, the sentence was "We will be rolling out the new feature by the end of the week". In this context, to roll out means to introduce to the public. It implies a smooth motion (figuratively) from the environment where the team is making the feature to the users. Just rolling instead of rolling out is not normal English usage in this context, though the intended meaning is clear.
To answer the edit, no, just saying roll instead of roll out is unnatural and I've never seen anyone do it. Roll out what we'd call a phrasal verb, which means the preposition is a part of the verb itself, and neither can be understood without the other. Don't drop the out!
