Question about the updated ISO file for VBR 13.1.1.18 (released on September 8, 2026)

[K-taira]

Hello everyone!

I have a question regarding the ISO file for VBR 13.1.1.18 that was released on September 8, 2026.

[ Background ]
I am planning to upgrade our environment from VBR 13.0.2.29 to 13.1.1.18.
As of September 7, 2026, I had already downloaded the VBR 13.1.1.18 ISO file from the download page ( https://www.veeam.com/products/download ... rsion.html ).
However, when I checked the download page again on September 8, 2026, I noticed that although the version remains the same (13.1.1.18), the release date has been updated to September 8, 2026, and the SHA256 hash value of the ISO file has also changed.
- Currently published SHA256 hash value: 3c5f058f5774a8ef5053d6e6267a5d38c61f2e874741e27bfa8fd375d751618e
- SHA256 hash value at the time of my download (September 7): ef7d72458cd617c760d8fe84438cdae9f1cf7b3caeb14424446e918492a7384d

Therefore, I would like to know what changes were made to the September 8, 2026 version of the ISO, and whether it is safe to proceed with the upgrade using the ISO file downloaded prior to September 8.

[ Questions ]
1. Could you please let me know what specific changes or updates were introduced in the ISO file released on September 8, 2026?
2. Is it safe to use the ISO file obtained before September 8, 2026, as is?

[ My Investigation So Far ]
According to the "ISO Release History" section of KB4738 ( https://www.veeam.com/kb4738 ), the VBR 13.1.1.18 ISO was initially released on August 12, 2026, and subsequently updated on September 1, 2026, to bundle the latest Veeam Plug-in for Google Cloud (v8). However, as of the time of writing this post, I could not find any information regarding the September 8 update in this KB article.

Additionally, looking at the release dates of other Veeam products on the download page, I noticed that the following products were released on the same day (September 8, 2026):
- Veeam Plug-In for Red Hat OpenShift Virtualization (Linux, 13.1)
- Veeam Plug-In for Red Hat OpenShift Virtualization (Windows, 13.1)

Based on this, I suspect that the VBR ISO was repackaged on September 8 simply to bundle the latest versions of these plug-ins. If we do not plan to use these plug-ins, I assume it should be fine to use the ISO file obtained prior to September 8. However, I am unable to confirm if this assumption is correct.

Thank you in advance for your help and clarification!
