Scroll Viewport 2023-12-21 is a hot fix release to provide a workaround for a bug introduced by Confluence.
The bug with Confluence's search endpoint returned a wrong count of pages which broke our code that calculates how many pages there are in a content source.
The wrong page count information created errors in the Viewport changelog (showing pages as deleted that have not really been deleted) and caused site generation failures.
The workaroud in this release fixes these issues.
Update as of : Confluence has now fixed the bug and we will retire the workaround with our next release early in the next year. Please note, for Viewport sites with very few pages you might experience some slower site generations until our next release.
