While existing Scalar 1 books will continue to be supported indefinitely, at some point we will permanently default all newly-created books to the new interface. Authors wishing to switch a Scalar book designed in the old interface to Scalar 2 should keep the following in mind:
- Scalar 2 offers many new layout options for media. All Scalar 1 media, however, will default to being right-aligned, medium sized, and will display their description as a caption. Changing these settings will require re-linking the media. (For more on the new media layout options, see the section New Focus on Media).
- Any custom CSS styling done in the old interface most likely won't work anymore, and should be removed.
- Visualization views for individual pages now generally focus on relationships to the current page (for instance, only pages tagged by the current page) over showing all content in the book. For whole-book visualizations, users can use the selection of visualizations available in the "Visualizations" sub-menu in the header.
- Media contained in annotations and notes will not be shown in the new interface. That is, if you've made an annotation of a video or image, and included another video or image within the content of that annotation, only the text of the annotation, and not the media, will be displayed when the annotation is shown. Likewise, if you've created a note which previews a page with a video or image on it, only the text of that note will be shown when readers click on the link. Display of embedded media in annotation and notes should be added soon, however.
