Discrete states of the tree are called ''revisions'' and are represented by immutable transactions. Each snapshot (except for the first, which has none and is called ''revision 0'') has exactly one predecessor and at most one immutable successor. Any number of mutable transactions can exist at the same time. The set of revisions is a temporally ordered sequence; the last or ''youngest'' revision is called the ''HEAD''. New revisions are created by ''merging'' the changes described by a mutable transaction with the tree state represented by HEAD and appending the resulting revision to the sequence, creating a new HEAD.
