This is the release notes for XWiki Commons, XWiki Rendering and XWiki Platform. They share the same release notes as they are released together and have the same version.

This is a bug fix release that fixes several regressions and improves the realtime WYSIWYG editor to create new revisions only when there are actual content changes and to avoid losing unsaved changes by mistake. This release also contains security fixes, with the highest severity being 5.3/10.

New and Noteworthy (since XWiki 16.10.12)

Full list of issues fixed and Dashboard for 16.10.13.

New security check on external URLs

A new security mechanism related to URLs has been put in place in XWiki to inform users when they click on a link leading to an external URL that does not belong to the list of trusted domains. This mechanism reuses the list of trusted domains that can be configured in xwiki.properties, and a new configuration has also been provided to allow specifying specific URLs that can be accessed without any warning from the frontend. Finally it's possible to also disable the new security mechanism thanks to a dedicated configuration. 

#-# [Since 17.9.0RC1]
#-# [Since 17.4.6]
#-# [Since 16.10.13]
#-# Allow to enable or disable checks performed when clicking links in the UI based on the list of trusted domains.
#-#
#-# By default this property is set to true:
# url.frontendUrlCheckEnabled=true

#-# [Since 17.9.0RC1]
#-# [Since 17.4.6]
#-# [Since 16.10.13]
#-# Allow to allow specific URLs to be accessible from the frontend without asking confirmation, and without
#-# needing to allow and entire domain. The expected format is absolute URLs separated by commas, e.g.:
#-# https://github.com/xwiki/xwiki-platform,https://www.xwiki.org/xwiki/bin/view/Main/WebHome
#-#
#-# By default this property is empty:
# url.allowedFrontendUrls=
