[protocol] Introduce optional deselectAll flag for SelectActions #257
[protocol] Provide the common interfaces and type definitions for TS-based GLSP servers #245 - Contributed on behalf of STMicroelectronics
[diagram] Introduce a new set of accessability features for disability-aware conceptual modeling and keyboard-only diagram interactions. (experimental) #240 #241 #242 #254 #276 #279
[API] Re-work tool and feedback structure #264 #274
- Introduce registerListener method on GLSP mouse and key tool to return a disposable for de-registration
- Adapt registerFeedback method from feedback dispatcher to return a disposable for de-registration
- Introduce dedicated BaseGLSPCreationTool for tools based on trigger actions
- Introduce toDisposeOnDisable collection in BaseGLSPTool to register disable handling during enablement
[DI] Introduce and consistently use FeatureModules instead of plain inversify ContainerModules #267
[diagram] Introduce statusModule that binds UI extension to handle & render GLSPStatusMessages. #272
[diagram] Provide generic dirty state handling in EditorContextService #272
[diagram] Fix bug that broke edge edit (routing) in certain cases #273
[API] Introduce DiagramLoader component + life cycle management #274 #282
- Integration projects no longer need to manually implement the initial diagram loading. Instead a set of configurationsIDiagramOptions and then the diagram loader is invoked and initializes the diagram.
- Add a onServerInitialized event to the GLSPClientAPI.
- Introduce IDiagramStartup service. Adopters can multi bind this service to hook into the diagram loading lifecycle and provide additional logic. i.e. dispatching of initial actions.
[diagram] Fix a bug that broke edge intersection detection when using the GLSPProjectionView #275
[diagram] Fix a bug regarding focus handling when integrated in an application frame like Theia #278

Breaking Changes

[DI] Injecting an IButtonHandler constructor is now deprecated. Please use configureButtonHandler() instead. #195 - Contributed on behalf of STMicroelectronics
[node] Update minimum requirements for Node to >=16.11.0 #210
[protocol] Renamed UndoOperation and RedoOperation to UndoAction and RedoAction to match operation specification #216
[protocol] Remove dependency to vscode-ws-jsonrpc. The protocol package now directly offers functions to create a websocket rpc connections #215
[protocol] The elementIds property of LayoutOperation is now optional. If undefined the entire model will be layouted #232
[API] Refactored base API #259
- Removed the TYPES.SelectionService service identifier. Please directly use the SelectionService class as service identifier instead
- The SelectionService binding is now part of the defaultGLSPModule. This means the SelectionService remains available even if the selectModule is not configured
- RootModelChangeListeners are no longer tied to the FeedbackawareUpdateModelCommand instead they are managed by the GLSPCommandStack
- IMouseTool and TYPES.IMouseTool are no longer available. Directly inject and use MouseTool instead
- Refactored rank utility functions
  - isRanked() -> Ranked.is()
  - getRank() -> Ranked.getRank()
  - DEFAULT_RANK -> Ranked.DEFAULT_RANK
[API] Introduce Event API to replace the old listener/notifier pattern #261
- Reworked SelectionService, GlspCommandStack & EditorContextService to make use of this new API
- Removed explicit (de)registration methods for listeners. Use the corresponding event property (e.g. SelectionService.onSelectionChanged) instead
- Aligned naming of injectable interfaces & service identifiers to consistently use the I prefix
[API] Re-work tool and feedback structure #264
- Remove generic toolsModule and toolFeedbackModule in favor of individual tool modules
- Rename dispatchFeedback in BaseGLSPTool to registerFeedback to align with feedback dispatcher
- Switch arguments in deregisterFeedback in BaseGLSPTool for easier de-registration and clean up actions
[protocol] Add messages for server-side progress reporting and remove timeout in ServerMessageAction #265
[DI] Renamed and aligned prefixes of DI modules. #266
- Removed glsp prefix from all modules (e.g. glspSelectModule-> selectModule)
- In addition, the following modules have been renamed
  - defaultGLSPModule-> baseModule
  - modelHintsModule -> typeHintsModule
  - enableDefaultToolsOnFocusLossModule -> toolFocusLossModule
  - glspEditLabelModule -> labelEditModule
[websocket] Introduce a reusable GLSPWebSocketProvider class that supports reconnect on connection loss #269
[API] Introduce GLSPModelSource as default implementation for sprotty's ModelSourceAPI #272 #287
- GLSPDiagramServer has been deprecated and is no longer available
- SelectionServiceAwareContextMenuMouseListener renamed to GLSPContextMenuMouseListener
- SourceURIAware interface has been removed. No longe required since we only have one GLSPModelSource binding now.
[protocol] Revise TypeHints API and introduce possibility to dynamically query the server for complex connection conditions #285
- EdgeTypeHint
  - sourceElementTypeIds and targetElementTypeIds are now optional. If not provided all connection targets are allowed
  - Introduce dynamic flag. If a hint has this flag enabled connection tools know that the have to query there server in addition to checking the default Connectable.canConnect method.
- Introduce RequestCheckEdgeAction & CheckEdgeResultAction used to query the server wether the provide edge information is valid. Used in combination with dynamic type hints.
[protocol] Refactor base protocol & actions #287
- Rename ServerStatusAction -> StatusAction
- Rename ServerMessageAction -> MessageAction
- Extend InitializeClientSessionParams with a clientActions property. This is used by the server to now which action kinds are (also) handled by the client.
[API] Update to sprotty 1.0.0 and consistently use GModel naming scheme on client side [#291(https://github.com/eclipse-glsp/glsp-client/pull/291)]
Move augmented GLSP reexport of sprotty into dedicated package @eclipse-glsp/sprotty
With sprotty 1.0.0 the SModel classes haven been renamed by adding an Impl suffix (SModelElement->SModelElementImpl). We took this opportunity and aliased all sprotty model elements to consistently use GModel
- SModelElement -> GModelElement
- SNode-> GNode
- SShapeElement->GShapeElement etc.
