Important changes

Sitecore logging

The time for keeping Sitecore log files has been increased to 30 days. (426814)

New features & improvements

Marketing Foundation

  • Memory usage has been optimized in the ContactBulkUpdateManager.

  • The Tracker extension for registering outcomes now sets the date and time for the outcome.

Sitecore supportability improvements

  • A Sitecore dumping configuration feature on every Sitecore restart has been implemented. The DumpConfigurationFiles processor has been added to the Sitecore <initialize> pipeline. The processor is defined in the Sitecore.Diagnostics.config configuration include file and supports various configuration settings, such as the location for storing configuration files, support for compressing, and files to be tracked. By default, dump files are stored in /diagnostics/configuration_history in the Data folder. (373420)

  • Periodic dumping data from /sitecore/admin/stats.aspx and /sitecore/admin/cache.aspx pages to the file system has been implemented. New processors have been added to the <healthMonitor> pipeline. The location and format of the log file can be configured as part of the processor configuration. By default, dump files are stored in /diagnostics/health_monitor in the Data folder. (415409, 415411)

Resolved issues

  • An empty alert dialog appeared in the Content Editor when creating an item with a name that contained characters specified in the InvalidItemNameChars setting. This has been fixed. (431321)

Control Panel

  • The display language was not changed after refreshing the browser when a user changed the language in the Regional and Language Options dialog of the Control Panel. This has been fixed. (428168)

  • An exception occurred when you opened any application in the Control Panel after a user session had expired. This has been fixed so that the user is redirected to the Sitecore Login page. (429931, 435805)

Engagement Analytics

  • Importing users to an engagement automation plan was slow. This has been fixed. (431530)

  • Viewing automation states that contained a large number of contacts was slow. This has been fixed. (431493)

  • The WriteConcernException exception sometimes appeared in the Sitecore log file when users were enrolled to a state of the engagement plan. This has been fixed. (430655)

  • Analytics Exceptions were not handled properly and appeared in the UI causing the site to be broken. This has been fixed. (428886, 432992)

Multibrowser fixes

  • [IE11] The Select Media Item dialog header was rendered in the wrong place. This has been fixed. (430149)

Package Designer

  • An empty dialog appeared when trying to generate the Sitecore package if the /data/packages folder was missing. This has been fixed so that a missing /packages folder is automatically created and a warning message about this action is added to the Sitecore log file. The same problem was fixed in the Installation Wizard when you click the Upload package button. (428852, 430197)

  • The DirectoryNotFoundException exception appeared when you tried to create a new package from an existing one. The problem occurred only if the /Data/package folder was missing. This has been fixed so that a packages folder is created automatically. A warning message is added to the Sitecore log file. (435796)

Potential security vulnerabilities

  • The password recovery page showed different validation messages when a user with a specified name already existed in the Sitecore database. This has been fixed so that a generic validation message is shown. (363086)

  • A potential cross-site scripting vulnerability has been fixed in the media upload control. (415861)

  • Potential cross-site scripting vulnerabilities have been fixed in the logic responsible for processing query parameters in the SiteContext class. (416948)

  • Potential cross-site scripting vulnerabilities have been fixed in the Content Editor application, Edit User dialog, and Sitecore Desktop. (428980, 428986, 429290, 432461)

  • The Search tab in the Content Editor returned the search result event after a user session had expired. This has been fixed so that a user is redirected to the Login page. (429472)


  • The ArgumentOutOfRangeException exception appeared during publishing if the site defined in the sites section in the Sitecore configuration did not have the renderingParametersCache attribute. This has been fixed. (432979, 433131)

Sitecore.ContentSearch API

  • An error with the message "undefined field" sometimes appeared in the search log file when using the Solr search provider, despite the fact that the field existed and had the appropriate type. This has been fixed. (429492, 429702)

Update Installation Wizard

  • The Update Installation Wizard did not support installing files into the Data folder located outside the Sitecore instance. This support has been implemented. The new version of the wizard is compatible with previous Sitecore versions. (429063, 434126)

  • The installation of the update package sometimes stopped responding and never finished. This has been fixed. (434755, 432536)

  • A warning message with the text "The standard values field of template <template path> does not contain an ID that points to a child" appeared in the Sitecore log file after installing an update package. This has been fixed. (428666, 432309)


  • A virtual user remained logged in to Sitecore but lost all assigned roles after the user session expired. This has been fixed so that the virtual user does not lose their roles while they are logged in. (365855)

  • Sitecore did not track the situation when a Sitecore setting with the same name was defined in the Sitecore configuration more than once. This has been fixed so that Sitecore outputs a warning to the log file if a setting with a duplicated name is defined. (380315)

  • Roles added to a virtual user after they were logged in were not preserved between requests. This has been fixed. (381352)

  • If a virtual user was logged in to a shell site, the InvalidOperationException error occurred when they tried to access http://<hostname>/sitecore URL. This has been fixed. (408264)

  • The requested item was not resolved correctly if the item content path contained a combination of characters specified in the replace node of the encodeNameReplacements section. This has been fixed. (408384, 416567, 416797, 431208, 434065 )

  • The ObjectDisposedException exception sometimes appeared in the Sitecore log files right before or after a Sitecore restart. The problem was in the Sitecore scheduled tasks that continued running and trying to access already disposed objects. This has been fixed so that scheduled tasks are stopped during the shutdown. (431037, 433802)

  • Experience Analytics reports were empty after migration from Sitecore 7.5 to Sitecore 8.0. The reporting database was missing some data. This has been fixed so that a special page has been added to the /sitecore/admin folder that can deploy missing information. The page can be used for any Sitecore 8.0 and higher release. (431335).

  • The Sitecore.Kernel assembly did not have the correct assembly version information. This has been fixed so that the assembly version for some Sitecore assemblies has been corrected. (433193)

  • Partial clearing of the ItemPathsCache performed badly on a heavy Sitecore load. This has been fixed. (434425)

  • This section provides reference numbers for scenarios reported by Sitecore customers that have been addressed as part of the other fixes or are no longer reproducible. (411992, 428639, 428805, 429328, 429920, 431296, 428666, 434755, 431335 )

  • It was impossible to change the language in the Experience Editor when the languageLocation attribute was set to "queryString". This has been fixed. (424740, 424491)
  • The MVC Experience Editor failed when a test was present on the page. This has been fixed. (432686; 432325)

  • The DialogWindow positioned its header inappropriately in IE11. This has been fixed with IE 11 specific CSS code. (44803)

Email Experience Manager (EXM) — formerly Email Campaign Manager (ECM)

  • When customers dispatched email messages synchronously on several threads, performance was severely degraded. This has been improved with several performance fixes. (431762)

  • The dispatch pipeline was often aborted if there was an error, even if the error was non-critical. This has been changed so the dispatch pipeline is now paused instead, allowing customers to fix the problem and resume the dispatch. (434929)

  • There was an error when viewstate failed to load in the Select Role dialog. This has been fixed. (430969)

  • The Beacon API was not loaded if the domain item had the rule "starts with path". This has been fixed. (39056)

List Manager

  • Exceptions caused by the UnlockContactLists agent (due to the disposed Lucene Index) have now been fixed. (42722)
  • Previous versions of the List Manager sometimes encountered memory issues and slower performance during bulk upload operations. This has now been resolved. (42723)
