Dear Qubes Community,
As [previously announced](Qubes OS 4.0 reaches EOL on 2022-08-04 | Qubes OS), all releases in the Qubes 4.0 series (which includes the most recent 4.0.4 patch release) have officially reached EOL (end-of-life) as of today, 2022-08-04. We strongly urge all remaining Qubes 4.0 users to [upgrade to Qubes 4.1](How to upgrade to Qubes 4.1 | Qubes OS) immediately. As always, the support statuses of all Qubes OS and template releases are available on the [supported releases](Supported releases | Qubes OS) page, and the latest release is available to download on the [downloads](Download Qubes OS | Qubes OS) page.
## What should I do?
If you're already using Qubes 4.1, then no action is required on your part. This announcement concerns only the 4.0 minor release series.
If you're still using Qubes 4.0 (including the most recent 4.0.4 patch release), then you should upgrade to 4.1 immediately. You have two options:
- Perform a clean reinstallation using the latest stable [Qubes 4.1.1 ISO](Download Qubes OS | Qubes OS), which was [published on 2022-07-18](Qubes OS 4.1.1 has been released! | Qubes OS).
- Perform an [in-place upgrade](How to upgrade to Qubes 4.1 | Qubes OS) to 4.1.
Both of these options are covered in further detail in the [Qubes 4.0 to 4.1 upgrade guide](How to upgrade to Qubes 4.1 | Qubes OS). If you need help, please consult our [help and support](Help, support, mailing lists, and forum | Qubes OS) page.
