2sxc 21.02

General Enhancements

1. 🩸 Oqtane: Multi-Tenant support still being enhanced (previous release had some upgrade bugs.)
2. 📖 Improve docs - especially the Contribute to Code section

💲 OData (Major Updates)

1. 💲 OData: Introduce $casing query option to control casing of returned JSON properties ($casing=camel)
2. 💲 OData: Make sure that OData parameters on a query only apply to the primary Default stream.
3. 💲 OData: Introduce ability to specify other parameters by stream, so that $select applies to the Default stream, but Books$select applies to the Books stream. (BETA, may still change)
4. 💲 OData: Reorg code structure (internal)

🌪️ Data Sources and Visual Query (Major Updates)

1. 🌪️ Create generic SysData DataSource to provide quick access to all kinds of data to the UI.
2. 🌪️ Introduce Confidentiality model for data sources, so that SysData doesn't leak data to the UI which the user shouldn't see.
3. 🌪️ Create query System.SysData to provide access to SysData in queries and REST APIs.
4. 🌪️ Introduce * (internal) wildcard Visual Query connections to pass all streams from one DataSource to another without having to specify them all. This is especially useful for SysData which can have many streams.
5. 🌪️ ✏️ Improve VisualQuery UI to properly support * wildcard connections, and to show them in the UI with a different style to indicate that they are dynamic.
6. 🌪️ ✏️ Improve VisualQuery UI to show tabs by stream name, making it easier to see the results

5. 🧑🏼‍💻 ✏️ Enhance UI to manage code-generation configurations

💃🏼 Models

1. Introduce TryGetMetadata<T> to get metadata of a content-type, which is especially useful for code-generation scenarios where you want to check if a content-type exists and get its metadata without throwing an exception.
2. Improve Model lookup to support interfaces which can define which class/record to use
3. Introduce the INoteModel to access Notes Metadata on items/pages/modules etc.

Minor

(none)

Bugfixes

1. 🐞 Fix UI to configure Pickers - problem was with the Attributes DataSource.
2. 🐞 Fix Polymorphism in Admin UI (Views), broken in v21.01

Internal and Code Hygiene

1. 🧑🏼‍💻 EAV-UI: Introduce a generic SysData service to easily work with SysData endpoints
2. 🌪️ Move various classes related to DataSource Queries to a better namespace
3. 🌪️ Visual Query: Refactor models, simplify
4. 🌪️ Improve internal DataSource construction, to use our new standardized Setup(options) mechanism

6. 🔌 API: Move RecycleBin to use DataSources instead of APIs

Experimental / WIP

1. Introduce IDataProcessor to customize how data gets stored / loaded
2. Introduce DataStorageDecorator to specify how ContentTypes get processed
   1. Introduce a max-items limit to prevent accidental creation of too many items (for some content types, only 1 is allowed)
