Changes Report
![]()
The user notification filter preferences are now automatically updated when a watched page is moved/renamed.
Improved Database List Field


The Database List field that you can use when creating an application with AppWithinMinutes has been improved. It is now displayed by default using an input suggest picker that adapts to single and multiple selection. You can still change the display type if you want. If you choose the "Select" display type then you can also control its size.
"My Groups" user profile section has been renamed to "Groups"
![]()
Check View groups documentation for more information.
Additional information when a delete operation fails


When an error happens while deleting a page, detailed information are displayed to help understand the problem.
Display nice error message in case of path too long

In a few cases, an error might happen when creating a page, if its full path is too long. The full path is defined by the title of the page and the title of all parent pages. We now provide an UI for this error to explain what happens: the fix is generally to reduce the size of the title of the page, or to put it under another hierarchy.
Filesystem store location
![]()
It's now possible to set the location of the filesystem store without modifying the general permanent directory using property store.file.directory of the file xwiki.properties.
Display content in restricted mode
![]()
A new URL parameter is available for viewing pages in restricted mode.
You can now use restricted parameter, with the following values:
- false (default): the macro transformations are normally executed
- true: macro transformations are executed in degraded mode or not executed at all, depending on the macro implementation.
In particular, various scripting macro such as Velocity Macro or Groovy Macro are not executed in restricted mode.
This parameter might be then use to check if a page is well displayed for user who cannot execute those scripts for example.
Deleter can now restore
![]()
The deleter of a document is now allowed to restore it even without admin right (provided the user have enough right to create a document at this location).
Allow to store a StaticList value in a large string
![]()
When creating a Static List class, it is now possible to choose to Allow large string. This can be useful if this list aims at storing large values.
Allow to create Static List class with value suggestion

It is now possible to create a Static List class that will display a suggest picker for the values that are entered.
Note that the displayer is only available when using the input display type.
Line numbers in code macro

A new parameter has been introduced to enable line number display in the code macro. See Code Macro for more details.
Check user inactive status by default
![]()
If you configured the registration page to enable the Use Email Verification, then new registered users are by default inactive until they fill a form. Starting with this release the active status is checked by default at login. The previous option to enable this in the Administration > Registration page, Authentication Active Check, has been removed.
Tomcat 9 based Debian Package
![]()
Tomcat 9 is now the current stable branch of Tomcat so we provide a Debian Package of XWiki based on it.
Allow to disable the edit conflict mechanism
![]()
We introduced in XWiki 11.2 a mechanism that allows user to detect edition conflicts on a page and we are continuing to improving it. However this feature is still experimental and might have unwanted consequences on older extensions. So we added the possibility to completely disable the feature if needed, with a new property in xwiki.properties:edit.conflictChecking.enabled = true
You can set this property to false and restart the wiki in case of trouble. In that case, please let us know so we can improve our feature.
Allow to perform custom decisions in case of merge conflict
![]()
The Diff module now offers new APIs to enhance the 3-way merge operation. The MergeResult is now capable of returning a list of Conflict objects which gives some information about the conflicts that occurred during the merge. Those conflicts can be solved on a case-by-case basis by specifying some ConflictDecision in the MergeConfiguration that is passed to the merge operation.
The main goal here is to allow more fine-grained conflict resolution when performing a merge operation.
Display conflict information inside unified diff
![]()
The display diff API allows to display information about conflicts.
The APIs to build unified diff takes as input a list of conflict elements that have been computed during a merge: some conflict information are then available in the resulting unified diff blocks, and can be used to present conflicts and possible decisions inside an UI presenting unified diff.
Computed field values are now available in REST representations
![]()
In the REST API, the REST representation of objects containing computed fields now includes the computed values of these fields while previously, they contained an empty value.
Mail Configuration inherited from main wiki
![]()
The Mail Configuration for a subwiki is now inheriting from the configuration from the main wiki. More precisely if the local Mail.MailConfig is empty for the looked up configuration property, it's looked for in the same page in the main wiki, and if not found then it defaults to the value from xwiki.properties.
Possibility to disable the fullscreen behaviour on textarea
![]()
Until now a "maximize" link was automatically added to any textarea added to a page when viewing it in an editor. This can be now disabled by using the CSS class not-maximizable on the textarea.
Remove XWikiUser disabled property and introduce email_checked property
![]()
We introduced in a new property on XWikiUsers objects called disabled to allow to disable or enable users. This property was however redundant with the previously existing active property, which was until then only used to check if users validated their email account, when the linked registration option was activated.
In this release, we remove the disabled property and rely entirely on the active property to know if a user account is enabled or not. We introduced a new email_checked property to verify if a user validated his/her email address if the option was activated.
