I'm working on the CSL style for the latest China national standard which is being revised. It requires the version number of a preprint article (e.g., version "2" of https://arxiv.org/abs/1112.6136v2) and I'm requesting such a field in Zotero's preprint type. The expected format of the style is like:

> JENKINS S D, RUOSTEKOSKI J. Controlled manipulation of light by cooperative response of atoms in an optical lattice [PP/OL]. V2. arXiv (2012-03-18) [2020-06-24]. https://doi.org/10.48550/arXiv.1112.6136.
