    • ViewModel Analysis: Added Extras/ViewModelPlan - new experimental functionality to use LLM to help in ViewModel analysis.
    • Variable Dialog Improvement: The Add variable dialog now features an "As-collection" checkbox, streamlining the selection process.
    • Enum Ordinal Values in OCL: In OCL, EnumOrd now populates with the ordinal number of the enumerated value (0,1,2) for expressions like MyEnum.allinstances.EnumOrd.
    • OCL Enum Comparison: OCL now allows comparison between Enum.value and integer, falling back to EnumOrd.
    • Rescue Operations: Added "Move column out of conflict position" as a new Rescue operation.
    • ViewModel ShownByAction: ViewModel ShownByAction now indicates if it is popup, modal, or normal.
    • LiveEdit Tab: New Tab in LiveEdit - advanced-styling, work in progress.

Framework

  • Enhancements
    • Advanced Styling: Major updates with LLM support and fast-track CSS.
    • Singleton Fetching: ExtentService has two new methods:
      • IObject Singleton(IClass c): Fetches or creates a singleton instance.
      • T Singleton() where T : class, IEcoObject: Fetches or creates a singleton instance with a generic type.
    • OCL Editor Assistance: OCLEditor has a new "Second pair of eyes" option that helps to spot issues with expressions (LLM powered).
      • Action Enable Expression Logging: Added the enable expression that gives false in the log when the server-side action is not allowed to run.
      • Native Type Combo Box: When listing native type values in a combo box and trying to assign one by pick, Turnkey now behaves better for datetime, bool, int, double, and decimal.
    • SelfVM Logging:
      • selfVM.LogEntry('say something') will output a row in MDrivenServer-log, Turnkey-log, and debugger OCL-trace.
      • selfVM.LogEntry fixes.
    • RESTful API Enhancements:
      • Added special name BYTEARRAYCONTENT to upload a single blob (no multipart content) with restPut, post, and patch. Works the same as STRINGCONTENT.
      • RestHead OCL operator added to only request headers from an external service.
      • vResponseHeaders variable: When found and a Rest call is made, this variable is populated with a return-separated list of header name:header-value.
    • Command Timeout: CommandTimeout option added to SQLImport and SQLExport functions in MDrivenServer.

Turnkey

  • Enhancements
    • Advanced Styling: Major updates to advanced styling with LLM support and fast-track CSS.
    • Web UI Alt-Key Navigation: Implementation of Alt-key in Web-UI (Blazor and Angularjs). First tries to focus toolbar, then main menu, and if already at the first item in either, tries the other.
    • AngularJS Popups: Reworked the use of transform in Turnkey Angularjs to use flex, resolving blurry font issues in popups.
    • StringFormatAngular Enhancement: Introduced numberhash:dec for StringFormatAngular, where number:2 is two decimals, but the new numberhash:2 is two decimals unless there are more decimals (e.g., 0.00#).
    • Binary Data Support: Added ability to post binary data to Turnkey exposed Rest service. Added single column BYTEARRAYCONTENT that receives blob, following the pattern of string data STRINGCONTENT - if the uploaded content is not a Form-record these 2 types are checked instead.
    • MDrivenServer Communication Logging: When the MDrivenServer was "Not Started" or unreachable, the Turnkey-log previously showed nothing. Now, TK log will clearly reflect communication breach with MDrivenServer.
    • Exception Tracking: SysTurnkeyTrace now also tracks Exceptions in the same structure as navigations.

Correctifs

Designer

  • UI & Usability Fixes
    • LiveEdit Tree Splitter: Issue with LiveEdit tree splitter fixed.
    • Turnkey Hotkey: Issue with Ctrl+Enter Turnkey hotkey showing Save even when nothing to save is fixed.
    • Turnkey Angular Double-Click: Issue with Turnkey angular double-click execute of a single action that navigates when holding control not opening in a new tab is fixed.
    • Blazor Shortcut Keys: Fixed "Asking before escaping" in Blazor shortcut keys.
    • LiveEdit GoView: LiveEdit GoView did not work correctly - fixed.
    • Tagged Values Dialog: Resolved strange ghost drags on columns and placing containers after opening the TaggedValuesDialog from a column's TV link.
    • ActionDefinition View: Removed the old ActionDefinition view.
  • Performance & Stability Improvements
    • WebView2 in LiveEdit:
      • Handled issue with WebView2 in LiveEdit being initiated too early.
      • Resolved deadlock issue when WebView2 sends a shortcut to MDrivenDesigner while MDriven starts a save, preventing the wait animation loop. Shortcuts from the web browser are now blocked.
    • Angular Client Control Keys: Fixed an issue in the Angular client where control keys did not fully execute their after-action due to a roundtrip fillup.
    • Debugger & SQLite: Fixed issues with the Debugger form and SQLite.
    • SQL Start Exception Handling: Implemented exception catching during SQL start to prevent the SQLink common issue from halting MSSql usage.
    • MDrivenServer Ticket Time: MDrivenServer SysAsyncTicket now uses utcNow instead of server now, and the model's file format has been updated.
    • .NET Framework Updates: Updates to enable MDriven VS2022 on ARM64, requiring .netFramework48 and VS 2022 (Version 17.13.6). .netFramework472 and older are no longer supported; .netFramework48 is now the minimum target. Users must update VS2022 and MDriven NuGets and ensure their projects target .netFramework48.
    • Namespace Issues: Namespace issues have been resolved.
  • Bug Fixes
    • Nuget Packages:
      • Azure.Core, Version=1.45
      • System.ClientModel, Version=1.2.1
      • System.Runtime.CompilerServices.Unsafe, Version=6.0.1.0
      • System.Threading.Tasks.Extensions, Version=4.2.1.0
      • System.Runtime, Version=4.3.1
      • System.Security.Cryptography.ProtectedData, Version=6.0.0

Framework

  • Bug Fixes
    • Angular Client Control Keys: Issue in the Angular client where control keys did not fully do their after-action due to a roundtrip fillup is fixed.
    • Variable Dialog: Add variable-dialog now offers an "As-collection" checkbox instead of having all the types all the time.
    • Tuple Cloning in Debugger: Issue in the debugger when cloning ViewModel variables and one is a Tuple is fixed.
    • Action Enable Expression Evaluation: A recent fix for actions accidentally broke evaluation if the action enable expression was empty - fixed.
    • Theme Upload: Theme upload did not happen unless there was a style - fixed.
    • Turnkey Development Service: The Turnkey/Development?view= service was untested and failed in certain cases. Fixed.
    • Keyboard Shortcuts: Changes for keyboard shortcuts for Save (Ctrl+S), SaveAndLock (Ctrl+Enter), EditMode (Ctrl+E), CancelAndLock (Esc), undo (Ctrl+Z), redo (Ctrl+Y) in Angularjs and Blazor-client.
    • DisplayMode Change Signaling: DisplayMode did not correctly signal change when changed - fixed.
    • SelfVM.CanExecute: selfVM.CanExecute ran into a problem when evaluating a placed button's enable expression if the placed button was on sub-nesting and not pointing to an abstract action (then it wrongfully used the context of the sub-level - but in these cases, the context is vmroot). Fixed.
    • SysViewStateCookie: SysViewStateCookie included the vSysReadOnlyMode variable - this was unintentional and it is not included in new SysViewStateCookies.
    • Cache Invalidation: Cache Invalidation was revisited and an assumption was proved wrong and rectified - old manifests were too big due to this oversight.
    • OclKindOf Operator: Discovered issue in in-memory OCL for OclKindOf (used internally to implement LINQ "is"). Class2.allInstances->select(GenSym_0|GenSym_0.Class1.OclIsKindOf(Class1A)) and self.Class1.OclIsKindOf(Class1A) gave true if single link "class1" was null - corrected in new builds.

THIS IS IMPORTANT: Update your VS2022, Update your MDriven Nugets, If you get build breaks check that YOUR THINGS TARGET at least .netFramework48.
