With this this issue NWR introduces a new publication model, which means that submissions are released online as soon as they have been accepted for publication. Issues will build gradually, with articles being added to the contents list as soon as they are ready. The "issue in progress" is the issue that is open and to which we are continuously adding new articles. At the end of the year, the issue is closed. It will then be typeset and published as an annual volume (Volume 9, 2020).

In this new model we no longer have specific deadlines for submissions. Received submissions are processed continuously, and those that are accepted after peer review are released online with as little delay as possible. See our continuous publication FAQ for further details. 

All accepted submissions are first published as "Preprint for Open Review" for four weeks. During this time, it is possible to comment on the article. After the four week open review period, the author has the possibility to revise the preprint version of the submission before final publication.
