End of Life (EOL) Policy Statement for Altair Monarch Desktop v15 English
Altair EmployeeGeneral Support Policy Overview
As Altair strives to deliver innovative solutions that create value for our customers, we periodically release new products or versions of products. Therefore, as part of a product’s lifecycle, older versions eventually reach their natural end of life. It is Altair’s goal to make this process as transparent as possible to Customers and Partners, thereby enabling our users to plan for upgrades and migrations toward supported product versions.
This article sets forth Altair’s End of Life (EOL) policy milestones and defines the life cycle of Altair Monarch desktop and the types of technical support available during this life cycle.
With the recent release of Altair Monarch 2021 we would like to inform you that Altair has begun the End-of-Support process for the following product:
-
Altair Monarch Version 15.X
We sincerely appreciate your support and regret any inconvenience this necessary action causes you. To facilitate the transition, we are providing key dates:
| Milestone | Definition | Date |
| End of Support | The last day to receive service & support. | January 30, 2022 |
Thank you for your loyalty and support.
Product Life Cycle and Support
Altair Monarch products support two concurrent major versions at the same time. With the release of Altair Monarch 2021 (SDK 17.X) the Monarch Desktop version 15.X will be end of lifed while Monarch versions 16.0 and 16.1 will continue to be supported.
Upgrade Resources
To get started, below are some useful resources: As per the support policy we only support the current plus one previous version and with this, we would highly recommend upgrading your Monarch to the latest version during this time frame to benefit from all the new features, security updates and many more.

Altair Monarch Server Considerations
Please note the latest version of Monarch Server (2020.x) supports models, projects, and workspaces from Monarch Complete 2020.1.1 or lower only.
Models, Projects, and Workspaces that are created or edited in 2021.0 or later contain features and enhancements that make these incompatible with Monarch Server 2020.x. The next major release of Monarch Server is due in November 2021 (Version 2021.0). This will have compatibility with Monarch Complete 2021.0 accordingly.
Use of mixed versions of Monarch Complete/Monarch Server when sharing models, projects, or workspaces should be avoided to minimize compatibility issues that can arise as a result.
The following table confirms desktop/server compatibilities;
| Desktop / Server | Monarch Complete | |||||
| 2020.0 | 2020.0.1 | 2020.1 | 2020.1.1 | 2021.0 | ||
| Monarch Server | 2020.0 | Yes | Yes | No | No | No |
| 2020.1.1 | Yes | Yes | Yes | Yes | No | |
| 2020.1.2 | Yes | Yes | Yes | Yes | No | |
