4K Support
VaultWiki 4.0.15 is the first version to contain built-in support for high-density displays, such as 4K monitors and retina devices. Both the wiki's attachment system as well as its image proxy will now automatically generate thumbnails for these devices, if enabled, and will serve the appropriate version for each device.Removal of Some Hard Limits
In earlier versions, there were various issues when an individual page appeared in over 200 categories, had over 200 translations, or reached similar limits in other features. As of 4.0.15, the maximum supported number of categories and translations per page is now effectively unlimited.However, while some improvements were made to books, limitations are still in effect regarding maximum supported book chapters. This will be addressed in a future release.
