@gb.123 Yes. If you think it's not clear in the blog post, I'll think how I can word it.
Current wording:
This announcement does not represent a new release. It applies to the existing XCP-ng 8.3.
If you're already running XCP-ng 8.3, you're on the LTS version. There's no need for a full upgrade. Standard package updates will keep your system current.
A new batch of non-urgent updates is ready for user tests before a future collective release.
openssh: Fix low priority CVE-2025-26465 DoS attack when VerifyHostKeyDNS is "yes" or "ask" (The Default value has not changed: "no")samba: Fix vulnerabilities which are very unlikely to be exploitable on XCP-ng but are reported by security scanners.xcp-ng-release: This update adds a certificate to resolve a TLS handshake error, particularly when deploying XOA from CLI using curl.From an up to date host:
yum clean metadata --enablerepo=xcp-ng-testing
yum update --enablerepo=xcp-ng-testing
reboot
The usual update rules apply: pool coordinator first, etc.
No specific steps for these updates for XOSTOR users.
openssh: 7.4p1-23.3.2.xcpng8.2samba: 4.10.16-25.el7_9xcp-ng-release: 8.2.1-16Normal use and anything else you want to test. The closer to your actual use of XCP-ng, the better.
None defined, but early feedback is always better than late feedback, which is in turn better than no feedback 
You probably saw it, but just in case: https://xcp-ng.org/blog/2025/06/16/xcp-ng-8-3-is-now-lts/
Today marks several important updates for XCP-ng 8.3. In a nutshell:
- It officially becomes a Long-Term Support (LTS) release, as previously announced when it was first released on October 7th, 2024.
- We are releasing updated installation images ("ISOs") that include installer improvements and all updates published since the original release.
- XOSTOR, our hyperconverged storage solution powered by LINSTOR, is now officially supported on XCP-ng 8.3.
- A new, dedicated upgrade ISO is available to support upgrading from an 8.2 pool that includes a XOSTOR storage repository.
The above issue is solved in packages that we haven't released as an update yet, that @Andrew tested.
We do advise to jump to 8.2 from earlier releases, before jumping to 8.3.
Ahh excellent news! Thanks for keeping us posted
Hi,
IIRC, you need a more recent kernel that the one in the Dom0 for that. So it will be possible with XCP-ng 9.0
@moterpent It sounds more like a firmware issue when trying to create new Boot#### UEFI variables rather than running out of disk space. It might help to delete some existing OS boot entries before attempting to install.
