| Version      | 1.15.0 |
| ------------ | ------------------ |
| Release Date | June 28, 2021 |
## Data and Model Management

* **Enhanced Datasets** configurations on the platforms:
    * Allow versioning and approval workflows in dataset registry
    * Enhanced registry page with additional notes, permissible purpose, and keywords
    * Create artifacts for datasets which can be tracked in the Artifact Repository
    * Allow modelling and non-modelling datasets by providing an optional target feature that can be used with the dataset
    * Lineage tracking for datasets
    * Ability to attach Flags for datasets
* **Improved performance for PMML** based models in Model Registry
* Enable **copying Rules in Quality Check**

### Policy and Strategy Management

* Simplified UX to associate models to a policy using ModelSuite

## Common

* Ability to **share** objects with other users in the Draft and Pending Approval stage. This enables more collaboration when developing objects before it gets Approved.
* **Approval Workflows** - The previous functionality provided by Approval Committee has been renamed to Approval Workflow with enhanced capabilities added: 
    * Veto power - to lock objects from being changed during reviews
    * Allow the same user to perform multiple responsibilities in a workflow
    * Add ability to add informational comments to an ongoing review
    * Enhanced timeline-view to track historical activities in an approval, which show simulations and comments
    * Allow sending a new job to reviewers when re-submitting the request based on changes or information requested
* Allow **editing the Permissible Purpose** for an object in a cloned version
* Allow **string comparison operators** like <, >, <=, >= in quality check rules and simulation filters
* Enable **exporting artifacts for Draft and Pending Approval objects**. To simplify debugging and testing for artifacts before it is sent for approval

## Technical

* Enable customization for various aspects of the platform to **integrate with 3rd party systems using generic methods like APIs, FTP, SSH, etc**.:
    * Allow **shortcuts** to other tools in the main navigation bar
    * Allow **exporting documentation** to system of choice
    * Allow **exporting artifacts** to system of choice
    * Allow **reviews and approvals from external tools** in an automated manner
* Enable users to hook into corridor's core actions using signals - like the review-signal. This is an advanced feature.
* Enable additional APIs to be added to Corridor which can be used to fetch information using the corridor python package via REST APIs
* **Improved Error messages** for various cases like:
    * Permission issues when a user accesses an object
    * Definition related errors in simulations, comparisons, and validation
    * Errors in the dependent variable computation for models
