| Version      | 1.20.0             |
| ------------ | ------------------ |
| Release Date | December 15, 2022 |


## Data and Model Management

* Allow a Model’s dependent variable or a Dataset’s target feature to use a Global Variable or Product Type Configuration which can be specified during the Simulation time.



## Common

* **Object change history:** Track changes which are happening on a Draft object and display them in a Change History page within the object. The Change History page also allows users to keep track of unread changes done to the object when it is shared with other users.
     * Also allow users to provide a comment explaining the change on all the object when saving changes to the object

* **Semi-automated input update:** Update the direct inputs of an object when newer versions of the input are available is now much easier. If a draft object needs to be created, it will be created automatically.

* **UI for report writing:** Allow reports to be written directly in the UI instead of as a configuration file which is deployed to the backend. This allows report writers to use version management, lineage tracking, etc. for reports - similar to other analytical resources.

* **Make Global Functions more flexible and easier to use:**
    * Support output type for Global Functions to document and define the return type from the global function.
    * Support use of global function and runtime parameters when writing a global function to allow direct usage when defining the function.
    * Allow default (optional) arguments for global function to avoid users explicitly providing all arguments.
* Users can now attach multiple simulations when requesting for a review.

* **Jobs accessibility:** Accessibility of jobs of an object is now tied directly with the object’s accessibility. Any user with Read access to an object can now view all the simulations that were run on that object (from all users).

   

## Technical

* Multiple performance speedups for various APIs.

* When users delete a job in the Corridor UI - internally this ensures that the spark application is killed or restarted. THis ensures that the cluster is freed up immediately which helps in improved utilization of resources.  

* Users who are using accessibility tools can now traverse and use the platform better - Accessibility improvements as per ADA (Americans with Disabilities Act) have been added.

* Technology support teams can now access more detailed logs on the workers to understand the steps that are happening within a job execution.

## Backward compatibility

* **Report Interface:**  The existing approach of creating reports using the backend configurations is deprecated. And the Resources > Reports should be used instead. We will continue to support the backend configuration based reports for a minimum of 2 major versions to aid in migration.
     
* **Database Support:** From this release on, the database support for MySQL 5 and SQL Server 2014, 2015 will be dropped. MySQL 8+ and Microsoft SQL Server 2016+ will be required.
