Image Owl uses the continuous integration and continuous delivery (CI/CD) development model to ensure that we release new changes to our customers quickly in a sustainable way. We deploy small batches of code changes to production regularly, usually weekly so that the code is fresh in developer's mind and there is a limited amount of dependencies to test. This allows us to be responsive to customer needs for bug fixes and new features while maintaining a robust and well tested code base.
Note: Equipment Hub versions are documented in the Revision History article. That revision history only contains changes to the Equipment Hub service itself. There may be related changes that are listed below that may also be of interest.
Release 25.06.18
Release Date: July 8, 2025
New Features
| Reference Number | Details |
|---|---|
| 3987 | Added support for import of Somatom Confidence Daily PDF's. |
| 3953 | When reverting back to defaults on a custom tests, added a popup that confirms whether or not the user wants to reset the test instructions. |

In cases where the conflict is a prior save, the user will be further prompted to refresh the page and reenter any needed data. In cases where there is a prior finalize the user will be further prompted to go the the report and reopen the report if needed and if they have permission. |
