#### Package linking configuration improvements

| Release Date | Version Number |
| --- | --- |
| 20th October 2025 | V4.7.2510.4206 |

Previously, packages could only be linked using their unique `PackageID`, which could become impractical in environments where packages are frequently updated. Each new package version generated a different `PackageID`, requiring users to manually reconfigure links every time.

Now, AAV can also link packages using the new `ApplicationID` variable, defined in the `CHMetadata.json` file, see Metadata (chmetadata.json) for more information. This `ApplicationID` is written to the Cloudhouse Root Key during deployment, allowing packages to be consistently identified across updates, making linking simpler and more reliable.
### Fixed issues

No issues have been fixed in this month's release of AAV.
