Breaking Changes in 2sxc 15.00


In summary we've made a lot of internal breaking changes. But for all normal users it will have no effect at all.

We believe it will only affect you in these scenarios:

  1. If you have a custom DataSource, you will need to make some minor changes and recompile them
  2. If you used special, non-public Logging APIs you would need to update your work
  3. If you used any undocumented APIs, you will need to check if everything still works

API Changes that may affect you

  1. DataSource base class was completely refactored
    see instructions
  2. Old static ToSic.Eav.DataSource was removed (deprecated since v13)
  3. Internal logging API ILog was completely refactored
    see instructions
  4. Internal object wrappers were completely refactored
    see instructions
  5. TinyMCE Upgrade to v6
  6. Database changes
  7. Minor API changes

Breaking Updates which probably don't affect anybody

  1. SQL changes - minor updates to the Database

    1. Static ToSic.Eav.Data.Builder.AttribBuilder.AddValue(...)

Breaking Changes in 2sxc 15.03


In summary we've made a lot of internal breaking changes. But for all normal users it will have no effect at all.

We believe it will only affect you in these scenarios:

  1. TODO

API Changes that may affect you

  1. An internal user property IUser.IsDesigner was renamed to IUser.IsSiteDeveloper
  2. An internal, deprecated user property IUser.IsAdmin was removed
  3. An internal, deprecated user property IUser.IsSuperUser was removed
  4. An internal property IUser.Guid was changed from Guid? to Guid
  5. The Users DataSource had a property called IncludeSystemAdmins which was changed from bool to string to allow for more options
  6. The Users DataSource had a property called RoleIds which returned a non-standard string-array. It has been removed, and the new Roles returns standard related entities.
  7. Removed static ToSic.Eav.Data.Build.Entity(...) method which was deprecated in v12

API Changes which should really not affect you

These are internal APIs which we changed to make everything more immutable. They should never have been in use outside of the internal code.

  1. Changed IValue.Languages from IList to IEnumerable and made it immutable
  2. Change IEntity.Attributes from Dictionary<string, IAttribute> to IImmutableDictionary<string, IAttribute> as a step to later make it immutable
  3. Removed some old, probably never used APIs on IAttribute<T> such as
    • IAttribute<T>[int[] languageIDs]
    • IAttribute<T>[string]
    • IAttribute<T>[string[]]
    • IAttribute[string[] languageKeys] - was always marked as private
  4. Changed the type of Attribute.Type from string to ValueTypes to make it more strong-typed
  5. Removed the property Attribute.ControlledType which previously contained the ValueType

  11. ✅ The Toolbar now has a new Info button which is used to show an info-bubble to the user or provide a help-link to somewhere. You'll soon see this in our standard apps to inform users about special cases such as "why the toolbar isn't available on demo-data"
  12. ✅ Bugs fixes
    1. ✅ 2sxc in DNN Skins on 404 pages
    2. ✅ Issue with Mobius Forms in v15.03

Breaking Changes in 2sxc 15.06


In summary we've made a lot of internal breaking changes. But for all normal users it will have no effect at all.

We believe it will only affect you in these scenarios:

  1. TODO

API Changes that may affect you on IEntity

These were internal APIs which were not publicly documented, but may have been used by some developers.

  1. IEntity.GetDraft() was removed to ensure the entity is immutable
  2. IEntity.GetPublished() was removed to ensure the entity is immutable

Note: GetDraft() and GetPublished() are still available on DynamicEntity in Razor and WebApi. They were only removed on IEntity.

Renamed DataSources

These data sources had uncommon names, and were renamed to be more consistent. We believe that they were only used in VisualQuery and not in code, so it should not affect you.

  1. CsvDataSource is now Csv
  2. SerializationConfiguration is now Serialization

Breaking Changes in EAV and 2sxc v14

We try to minimize breaking changes, and most breaking changes won't affect your work, because it's internal API. We're documenting it here to ensure you know what happened, in case you still run into this.


V14 did some clean-up of internal APIs, but otherwise there are no known breaking changes.

Breaking Changes in 2sxc 13.00

API Changes that may affect you

  1. An old, non-DI feature for Inner Content is being deprecated and will be removed in v14
    see instructions

  2. An old feature for publishing module InstanceData as JSON is removed
    see instructions

  3. An old feature to create DataSources is removed
    see instructions

  4. Two old data-conversion features DataToDictionary and EntitiesToDictionary were removed
    see instructions

  5. Some internal functionality which enabled IEntity objects to convert links containing file:... and page:... has been removed. This only affects special deep code calls on IEntity and does _not affect DynamicEntity objects in Razor see instructions

  6. The old feature Eav.Factory.Resolve<T>() was deprecated and will be removed in v14
    see instructions

  7. The old feature BlockDataSource.Cache.GetContentType(...) was removed see instructions

Major Updates with may affect you

  1. The Image Resizer is being replaced with ImageFlow
  2. The App containing Site-wide settings is changed to Primary - previously it used the Content app for this. We believe this won't affect many users, as the settings-stack is still very new in v12

Things which probably don't affect anybody

  1. SQL changes - minor updates to the Database
  2. .net Framework and Dll Updated to Match Dnn 9 Requirements - but still works in Dnn 7.4.2
    1. .net Framework 4.7.2 now required (previously .net Framework 4.5.1)
    2. .net Standard 2.0.3 required (previously .net Standard 1.6)
      Important: This will be referenced in the web.config upon installation
    3. Dependency Injection updated to .net core 2.1.1 (previously 1.1)
    4. Newtonsoft.Json updated to v10.0.3
  3. Entity Framework updated to 2.1.1 (previously 1.1) - Oqtane is unmodified and uses 3.1.4
  4. Dnn DLLs renamed
    1. ToSic.Sxc.Dnn.dll became ToSic.Sxc.Dnn.Core.dll for consistency
    2. ToSic.SexyContent.WebApi.dll became ToSic.Sxc.Dnn.WebApi.dll
    3. ToSic.SexyContent.Razor.dll became ToSic.Sxc.Dnn.Razor.dll
  5. An internal object ToSic.Eav.Apps.State was removed

Internal APIs which were removed

  1. Static ToSic.Eav.Data.Builder.AttribBuilder.AddValue(...)

  7. Moved IPageService from previously ToSic.Sxc.Web to ToSic.Sxc.Services but preserving compatibility with old code

Breaking Change Version 12.10

  1. Jquery is completely removed. This shouldn't affect your code, since all old code usually runs in DNN where jQuery is included by default.

Changes Version 12.06 LTS

No relevant changes

Changes Version 12.05

  1. Introduced IJsonService for json serialize/deserialize
  2. Introduced IConvertService for simple data-type conversion, also available on the Convert property of Razor12 and Api12
  3. Introduced ToSic.Sxc.Services.ILogService to log messages to the system (Dnn/Oqtane)
  4. Introduced IMailService to easily send mails cross-platform
  5. Introduced ISecureDataService to use encrypted settings
  6. Introduced IRenderService for inner-content rendering (Oqtane code must use this)
  7. Published ToSic.Eav.DataFormats.EavLight to better document simple eav data
  8. Published IConvertToEavLight as the new standard way to prepare entities for WebAPI serialization. This is meant to replace previous code using objects such as EntitiesToDictionary or DataToDictionary which are now marked as obsolete.
  9. New Razor12, Api12 and Code12 Classes now don't support old, obsolete APIs anymore
  10. Link.Image now also accepts parameters as a parameter
  11. Link.Image and Link.To always create safe urls now (spaces are encoded etc.)
  12. Link.To and Link.Image now have a parameter type which can be "full" to ensure domains are always added to links (for use in APIs generating RSS etc.)
  13. Update to RazorBlade v3.7
  14. Edit.Toolbar now supports condition so that toolbars may or may not be created based on a true/false value
  15. Link.Image now also accepts a factor or aspectRatio which is a string like 1:2 or 3/4
  16. AsDynamic(...) now also wraps anonymous objects in quite an amazing way
  17. Bugfix: lots of small ones

Breaking Change Version 12.05

V12 adds new properties to Razor and WebAPI which could result in some surprises: Path, Convert, Settings, Resources and DevTools. Especially the new Path and Convert could clash with existing code which had @using System or @using System.IO so the code would just read Path.GetFileName(...) or something. Because of this, we only give the latest classes Custom.Dnn.Razor12, Custom.Dnn.Code12, Custom.Hybrid.Razor12, Custom.Hybrid.Api12 etc. these properties.

This means that previous base classes do not have these by design, and we encourage you to move to these latest base classes.

Important: 2sxc 12.00 - 12.04 also had some of these properties on ToSic.Sxc.Dnn.RazorComponent as well as ToSic.Sxc.Dnn.ApiController. So if you were eager to use these properties but didn't change the base class, you were able to use it. To protect thousands of upgrade-scenarios we had to take them away from the old base classes. Sorry!

Possible Breaking Changes

  1. We believe nothing broke, but it could be that some commands on EntitiesToDictionary or DataToDictionary were accidentally changed. Pls report so we can fix that.
  2. The Link.To(...) now returns safe URLs. This should not be an issue, but in rare cases post-processing of the string returned may expect spaces or something, which are now %20
  3. We disabled old obsolete APIs on the new Razor12, Api12 and Code12 base classes. In case you were using this (not likely) you'll get an error telling you about this.

Changes Version 12.04 incl 12.03 which was not officially released

  1. Settings Stack and Resources Stack added, and the Settings / Resources object now have this
  2. Global settings defined for Content, Screen, Lightbox and Section
  3. Global defined for fancybox3, fancybox4, bootstrap4, bootstrap5
  4. Link.Image API created to support predefined sizes/resize modes etc.
  5. Created feature where DynamicEntities can browse to sub-items using their identifier (used for Settings.Images.Content where Content is actually the title of a sub-entity)
  6. Added debug-feature for DynamicEntity get
  7. String-Dropdown inputs now have a value-key presets option (instead of the key-value which was flaky) and added support for escaping special characters
  8. #Oqtane 2.2 support added
  9. Introduced Monaco (VS-Code online) editor for beta-testing source-editing

Breaking Change Version 12.04

  1. DynamicEntity now has a property Count because it's a list as well, this could cause issues if a content-type has a property Count
  2. DynamicEntity is now always a list. Because of this we removed the DynamicEntityWithList object. We believe the type is never referenced in user code, but if it is, this would be a breaking change.
  3. Many parts that prepare Entities returned a Dictionary<string, object> and now return an IDictionary<string, object>.
    We believe this shouldn't hurt much, since the result would usually be in a var or returend directly to the API for streaming, but in case someone had used explicitly typed code, this will require a minor change

Changes Version 12.02

  1. Formulas feature finalized
  2. DynamicEntityStack object created
  3. Hybrid IPageService created with Activate and similar features
  4. CmsContext was enhanced with View information
  5. Content-Type icons can now be stored in the app with an [App:Path]/image.jpg style reference
  6. Enabled view-configuration to configure search behavior incl. not-to-index or what streams should be indexed
  7. turnOn created / deployed
  8. #Oqtane 2.1 support added in 2sxc 12.02.01

Changes Version 12.00 Todo

Version 11

Changes Version 11.00

Breaking Changes

The following changes are all super-low-profile, but we want to document them just to be through:

  1. DataStream and IDataStream loses a very old property called .LightList - we're pretty sure it's not in use anywhere, if you have it, just use .List instead.


  1. Brand new Admin UI based on Angular 9 and Ivy with new Code-Editor, new VisualQuery and much more
  2. Razor CodeBehind
  3. Automatic Polymorphism

Changes Version 11.03 - todo

Changes Version 11.04 - todo

Changes Version 11.05

  1. Old Edit UI be removed
  2. Old Admin-UI be removed

Breaking Changes in EAV and 2sxc v11

We try to minimize breaking changes, and most breaking changes won't affect your work, because it's internal API. We're documenting it here to ensure you know what happened, in case you still run into this.


There were small breaking changes in 11.00 to 11.11 but they were internal so shouldn't affect normal developers.

Breaking Changes Version 11.07 - Drop the old edit UI

  1. In 11.07 the old edit UI was removed, so customizations for that UI would not be in effect any more.

Breaking Changes Version 11.10 - Mainly Dependency Injection

  1. In v11.10 we used much more dependency injection than ever before and stopped using static values which were still in the API in many places. Because of this, certain helper objects to create entities or lookup values were changed and their constructors were changed. We invested a lot of time to try to ensure that old APIs still work, but in case you're hit by one of these, make sure you check the DI and switch to resolving the objects using DI.

Breaking Changes Version 11.11 - Language Detection

  1. Previously the language detection used the Thread culture. Turns out this wasn't reliable because Dnn does some funny stuff (probably historical) which means that API-calls ended up using the language stored in some cookie instead of the one specified by the URL. We changed this, which should be more reliable. But if you were relying on this strange effect, then it may be a breaking change.
  2. Internally our tokens were also using the thread culture. When we changed this, we also had to change how tokens pick up the language. In rare cases this may affect you.
  3. We changed all tokens to always resolve boolean values to true/false (previously they would have been changed to the current language, like wahr for german). We believe this change is only an improvement, and should ensure that internal resolves in Queries etc. result in reliable output.

Breaking Changes Version 11.11 - DataSources: DataSourceConfiguration

Note that we also improved the DataSourceConfiguration to an interface IDataSourceConfiguration and documented this. As a side effect the API stays the same, but you will have to recompile your data sources for them to work again - sorry.

Breaking Changes Version 11.11.03 - IEntity Values

  1. IEntity had a command called Value(fieldName) which was probably never used. The idea used to be that it does language lookup internally, but we refactored this out since it could never be fully reliable because the full language list wasn't known to the IEntity. So we re-purposed the method (assuming it's not used) to just lookup the first occurance of the value. This way it`s useful for configurations and similar which are not multi-language.
  2. IEntity also had a Value(fieldname, lookup) method. We are deprecating it, and making the lookup not happen from now on. We believe it was never used.
  3. IEntity had a command called PrimaryValue(fieldName) which was probably never ever used, so we're deprecating it. Use Value(fieldName) instead.

Breaking Changes Version 11.11.03 - Other

  1. UI Toolbar dropped the button and command for item-history, as the history is now part of the edit dialog

Possibly breaking changes

  1. Because the dynamic entity list now has a type which is dynamic, it cannot be cast to List<dynamic> any more. IList<dynamic> works, but in case you have any code casting it to List<dynamic> you'll need to change that to either IList<dynamic> or IEnumerable<dynamic>.

New Features / Major Improvements

  • Fixed bug in JS API for non-2sxc endpoint resolution #2000
  • Queries didn't resolve Dnn tokens when accessed in the Search Index #1999

Breaking Changes in EAV and 2sxc

We try to minimize breaking changes, and most breaking changes won't affect your work, because it's internal API. We're documenting it here to ensure you know what happened, in case you still run into this.


Version 10 has a lot of small breaking changes because we restructured the internal API so it's consistent when we publish it. All these things shouldn't affect you, because they were internal APIs, but in case it does - here's what we did.

Version 10.22 and 10.23

  1. Renamed the RootDataSource and the Interface to IAppRoot
  2. Split SOC of the AppRoot DataSource so that caching, Root-Metadata and ListCache is fully separate
  3. Since the Logging system now auto-picks up the code lines and names of the methods, we simplified the commands and dropped some parameters.
  4. Moved quite a bit of the DataSource objects into sub-objects, again for SOC.

Version 10.20-04 (ca. 2019-12-03)

  1. Renamed DataTableDataSource to DataTable, old name still works.
  2. Renamed ExternalDataDataSource to ExternalData, old name still works.
  3. Renamed ToSic.SexyContent.DataSources.ModuleDataSource to ToSic.Sxc.DataSources.CmsBlock, old name still works.
  4. Renamed ToSic.Eav.DataSources.VisualQuery.VisualQueryAttribute to ToSic.Eav.DataSources.Queries.VisualQueryAttribute, old name still works.
  5. Renamed ToSic.SexyContent.Environment.Dnn7.Factory to ToSic.Sxc.Dnn.Factory, old name still works.
  6. Renamed ToSic.Eav.DataSources.BaseDataSource to ToSic.Eav.DataSources.DataSourceBase for consistency, old name still works.
  7. Moved the LookUp namespaces into the Core DLL

Version 10.20-02 (ca. 2019-11-22)

More internal changes which shouldn't affect anybody, but make the API ready for public docs...

  1. Moved/renamed the internal Eav.AppDataPackage to Eav.Apps.AppState
  2. Moved/renamed some internal interfaces like Entity...
  3. Did a major change for how Attribute<T> for relationships work.
    Before they were Attribute<EntityRelationship> and now they are Attribute<IEnumerable<IEntity>>.
    This also affects Value<EntityRelationship> which is now Value<IEnumerable<IEntity>>
  4. Moved Tenant<T> and Container<T> including matching interfaces to Eav.Environment
  5. Renamed IAppIdentity to IInAppAndZone and IZoneIdentity to IInZone
  6. Renamed ICacheKeyProvider to ICacheKey
  7. Renamed CacheChainedIEnumerable<T> to SynchronizedList<T>
  8. Moved/Renamed MetadataFor to Eav.Metadata.Target. Left old name compatible.
  9. Moved some extension methods for IEntity from ToSic.Eav.Data.Query to ToSic.Eav.Data
  10. Changed Permissions to be strong-typed EntityBased objects

Version 10.20.01 (2019-11-12)

  1. Internal code now uses the term Header instead of ListContent. External code provides both for backward-compatibility
  2. moved internal interfaces for engines (Razor/Token) to final namespaces ToSic.Sxc.Engines
    1. IEngine
    2. EngineBase
    3. ITokenEngine
    4. IRazorEngine
  3. corrected architecture - some template-management code had slipped into Eav.Apps, was moved back to Sxc.Apps
  4. The Template object was moved from Eav.Apps to Sxc.Views and we added an interface IView. We also renamed the internal properti ViewNameInUrl to UrlIdentifier.
  5. To correct the API a CmsManager was created extending the AppManager, which is in charge of Views
  6. Moving internal stuff related to content blocks
    1. IContentBlock from SexyContent.Interfaces to Sxc.Blocks
    2. from ToSic.SexyContent.ISxcInstance to ToSic.Sxc.Blocks.IBlockContext
    3. actually moved a lot of things there incl. ContentBlock now BlockConfiguration and more - all internal stuff
  7. Moving the ToSic.SexyContent.App to ToSic.Sxc.Apps.App
  8. In a razor page, we added the preferred Purpose. The old InstancePurpose will still work
  9. Placed some things we just moved in 10.20 to a final place - since it's a very recent change, we updated the docs in the 10.20.00 section

Changed, but completely internal

  1. Some namespaces on SexyContent.ContentBlocks were moved to Sxc.Blocks

Version 10.20.00 (2019-11-05)

  1. the internal interface IInPageEditingHelpers was moved from ToSic.SexyContent.Interfaces to the namespace ToSic.Sxc.Web
  2. the internal interface ILinkHelper was moved to ToSic.Sxc.Web
  3. the internal interface IHtmlHelper was moved to ToSic.Sxc.Dnn
  4. the property Configuration on dynamic entities was deprecated in 2sxc 4 and removed in 2sxc 10 - we don't think it was ever used
  5. moved internal Metadata interfaces (ca. 5) into final namespace ToSic.Eav.Metadata
  6. Moved a bunch of internal interfaces which we believe were never used externally from ToSic.Eav.Interfaces to ToSic.Eav.Data
    1. ToSic.Eav.Data.IAttribute
    2. ToSic.Eav.IAttribute<T>
    3. IAttributeBase
    4. IAttributeDefinition
    5. IChildEntities
    6. IContentType
    7. IDimension
    8. IEntityLight
    9. ILanguage
    10. IRelationshipManager
    11. IValue
    12. IValue<T>
    13. IValueOfDimension<T>
  7. Moved a bunch of internal interfaces which we believe were never used externally from ToSic.Eav.Apps.Interfaces to ToSic.Eav.Apps
    1. IApp
    2. IAppData
    3. IAppDataConfiguration
    4. IAppEnvironment
    5. IEnvironmentFactory
    6. IInstanceInfo
    7. IItemListAction
    8. IPagePublishing
    9. ITenant
    10. IZoneMapper
  8. the internal namespace ToSic.Eav.ValueProvider was changed to ToSic.Eav.LookUp and inside it
    we renamed a bunch of internal interfaces and objects which we believe were never used externally

Deprecated/Changed, but not broken

  1. the internal interface ToSic.SexyContent.IAppAndDataHelpers was renamed to ToSic.Sxc.IDynamicCode but the old interface still exists, so it shouldn't break
    it was used by Mobius Forms
  2. moved ToSic.Eav.Interfaces.IEntity to ToSic.Eav.Data.IEntity - but preserved the old interface for compatibility it was used everywhere

Clean-Up, but not broken

  1. We're transitioning to the term Header instead of ListContent in templates.
    The Razor pages and WebApi have this starting now, while old terms still work. Note that we're not creating a HeaderPresentation, because you should use Header.Presentation
