This is the third and final milestone of the XWiki Enterprise 4.2 version. This release brings new and improved UIs for file upload, logging configuration, an applications panel and the experimental
install/upgrade wizard. For developers this release introduces many features: a new file upload widget, minor improvements of the attachment picker and documents macros, the ability to add skin extensions located in JAR files, a
new field (mime-type) to index attachments by, an extension of the xar format and an experimental UI extension mechanism.
