Xpress Insight 4.57
With this release, we have added support forcustom scenario typesto Python-based Insight apps andremoved support for VDL and JS API versionsup to version 3.2.
Custom scenario typesallow to customize the behavior of the standard scenario or define new scenario types. It is possible to customize the display name and use dedicated scenario pill icons (for states unloaded, loaded and executed). Further, certain UI actions for a scenario type can be explicitly allowed or denied. It is possibly to execute custom logic in the code based on the type of scenario.
This way, a scenario type can be created that can only be instantiated programmatically, or additional layers of data management and custom model execution can be easily developed.
With this release weremoved support for VDL and JS API versionsup toversion 3.2to meet security standards. Please, update the VDL source files accordingly. Version 3.2 had been released before April 2017, while the current version is 4.7.
Xpress 8.12.2Mosel 5.6.1
With this release, we add adataframecapability inmmodbcbased on type ‘any’ and introduce anew Mosel module ‘mmreflect’.
Dataframecapability inmmodbc:
It is now allowed to read data from a database in adataframe-style: the model developer simply declares a two-dimensional array for which the line (counter) and column (field names) indices are automatically populated.
New modulemmreflect:
With the introduction of the type ‘any’ and this new module, we will provide an easy way to call functions and entities by name during run time.

- Scenario types are declared via decorators to theAppConfigclass and configured in the companion file.
- The type of a scenario and additional repository information can be retrieved via the newly added methodsget_item_infoandget_item_infosin thexpressinsightPython package.
- To use this feature, an update to thexpressinsightPython package is required. See theXpress release notesfor further details.
