Dear Qubes Community,
As [previously announced](Qubes OS 4.1 has reached end-of-life; extended security support continues until 2024-07-31 | Qubes OS), extended security support for Qubes OS 4.1 has ended as of yesterday, 2024-07-31. Qubes 4.1 will no longer receive updates of any kind, including security updates. We strongly recommend that any remaining Qubes 4.1 users [upgrade to Qubes 4.2](How to upgrade to Qubes 4.2 | Qubes OS) immediately.
## Recommended actions
If you're already using Qubes 4.2, then you don't have to do anything. This announcement doesn't affect you.
If you're still using Qubes 4.1, then you should upgrade to Qubes 4.2 immediately. There are two ways to do this:
1. Perform a [clean reinstallation](Installation guide | Qubes OS) using the latest stable [Qubes OS 4.2.2 ISO](Download Qubes OS | Qubes OS).
2. Perform an [in-place upgrade to Qubes 4.2](How to upgrade to Qubes 4.2 | Qubes OS).
Both of these options are covered in further detail in the [Qubes 4.1 to 4.2 upgrade guide](How to upgrade to Qubes 4.2 | Qubes OS). In either case, we strongly recommend [making a full backup](How to back up, restore, and migrate | Qubes OS) beforehand. If you need help, please consult our [help and support](Help, support, mailing lists, and forum | Qubes OS) page.
