New and Noteworthy (since XWiki <version - 1>)

Full list of issues fixed and Dashboard for <final version here even for RC, e.g. 10.5>.

For Users

  • Localized sizes and speeds in the attachment uploader:

    The attachment uploader now writes file sizes, upload progress and upload speeds with the units of the language XWiki is displayed in, for example 2.5MB/s in English and 2,5Mo/s in French. These units are decimal, a megabyte being 1,000,000 bytes, and files of a gigabyte or more are now shown in gigabytes. Learn how to attach a file to a page.

For Admins

No changes!

For Developers

  • Shorter HTML displayer template names for parameterized types:

    An HTML displayer template for a parameterized type can now use a short name built from simple class names, such as list(spacereference).vm for java.util.List<org.xwiki.model.reference.SpaceReference>. The fully qualified name is still looked up first, so a template can always target one precise type. See the picker documentation.
