Breaking changes in CMS 10

This document describes breaking changes for Episerver CMS in relation to previous version 9.0, and the steps needed to update affected code. To view the complete list of changes, see the release notes feed.

Some changes are binary breaking but do not necessarily require code changes but rather just a recompilation of the project. Breaking changes are changes in method signatures or behavior of methods compared to the documented API in the previous version, which are described in this document.

The new ".Internal" namespaces

One of the bigger changes is that all APIs have been reviewed to find internal implementation classes and that those have been moved to internal namespaces. You can see exactly which APIs are affected in these stories: CMS-3762 (Episerver CMS Core) and CMS-3755 (Episerver CMS UI). Read more about these changes in Henrik Nyström's blog post.

Event system

The event system (used primarily for communication between instances in a load-balanced environment) will no longer guarantee that events are being processed in sequential order one at a time. Code that uses the event system should be reviewed for thread-safety and cannot rely on the order in which events arrive to the event listener.
Implementors of custom event providers should also be aware that SendMessage calls are now longer guaranteed to run in a separate thread and should therefor take precautions to ensure optimal performance.

Remove support for legacy dot notation for dojo modules

We are removing the support for the legacy dot notation for dojo modules, for example, epi-cms.editing.ContentPicker. This means that you need to change all EditorDescriptors, Components etc where you have defined your Dojo modules using the . to /. Read more CMS-2295 and in Ben McKernan's blog post.

EPiServer.Shell moved to EPiServer.CMS.UI.Core

EPiServer.Shell.dll has been moved from NuGet package EPiServer.Framework to EPiServer.CMS.UI.Core. If you have both packages installed, no change is required. Read more in CMS-1380.

Note: If you get an error message saying Value cannot be null.Parameter name: virtualPath]in EPiServer.Shell.ShellInitialization.WaitForInitializeModules()..., remove the EPiServer.Shell.dll from the site bin folder. This may happen for sites that do not have the EPiServer.CMS.UI.Core installed, for example Commerce Manager.

Converting database to UTC a required step

Running the database with local date and time will no longer be supported (CMS-1449). A database that is not converted to UTC will throw an exception to avoid any data loss caused by mixing local and UTC date and time. Conversion can be done before upgrading for versions 9.1 or later, for example using the provided PowerShell scripts, see Storing UTC date and time in the database for more details. A setting can be added to the appSettions section of web.config to disable the exception if the site temporarily have to be started without doing the conversion, add episerver:DisableDateTimeKindValidation with value true.
