Simply [download](https://www.qubes-os.org/downloads/) the Qubes 4.3.1 ISO and follow our [installation guide](https://doc.qubes-os.org/en/r4.3/user/downloading-installing-upgrading/installation-guide.html). + +- If you're currently using Qubes 4.2, make sure to [upgrade from 4.2 to 4.3](https://doc.qubes-os.org/en/r4.2/user/downloading-installing-upgrading/upgrade/4_3.html) no later than 2026-06-21, which is when [4.2 will reach EOL](https://www.qubes-os.org/news/2026/04/27/qubes-os-4-2-approaching-end-of-life/). + +- If you're currently on Qubes 4.3 (4.3.0 or 4.3.1-rc1), [update normally](https://doc.qubes-os.org/en/r4.3/user/how-to-guides/how-to-update.html) (which includes [upgrading any EOL templates and standalones](https://doc.qubes-os.org/en/r4.3/user/how-to-guides/how-to-update.html#upgrading-to-avoid-eol) you might have) in order to make your system essentially equivalent to the stable Qubes 4.3.1 release. No reinstallation or other special action is required. + +In all cases, we strongly recommend [making a full backup](https://doc.qubes-os.org/en/latest/user/how-to-guides/how-to-back-up-restore-and-migrate.html) beforehand. + +## Known issues in Qubes 4.3.1 + +It's possible that templates restored in 4.3.1 from a pre-4.3 backup may continue to target their original Qubes OS release repos ([#8701](https://github.com/QubesOS/qubes-issues/issues/8701)). After restoring such templates in 4.3.1, enter the following additional commands in a dom0 terminal: + +``` +sudo qubes-dom0-update -y qubes-dist-upgrade +sudo qubes-dist-upgrade --releasever=4.3 --template-standalone-upgrade -y +``` + +This will automatically choose the templates that need to be upgraded. The templates will be shut down during this process. + +Fresh templates on a clean 4.3.1 installation are not affected. Users who perform an in-place upgrade from 4.2 to 4.3 (instead of restoring templates from a backup) are also not affected, since the in-place upgrade process already includes the above fix in stage 4. For more information, see issue [#8701](https://github.com/QubesOS/qubes-issues/issues/8701). + +[View the full list of known bugs affecting Qubes 4.3](https://github.com/QubesOS/qubes-issues/issues?q=is%3Aissue%20type%3ABug%20label%3Aaffects-4.3%20-label%3A%22R%3A%20cannot%20reproduce%22%20-label%3A%22R%3A%20declined%22%20-label%3A%22R%3A%20duplicate%22%20-label%3A%22R%3A%20not%20applicable%22%20-label%3A%22R%3A%20self-closed%22%20-label%3A%22R%3A%20upstream%20issue%22) in our [issue tracker](https://doc.qubes-os.org/en/latest/introduction/issue-tracking.html). + +## What's a patch release? + +The Qubes OS Project uses the [semantic versioning](https://semver.org/) standard. Version numbers are written as `[major].[minor].[patch]`. Hence, we refer to releases that increment the third number as "patch releases." A patch release does not designate a separate, new major or minor release of Qubes OS. Rather, it designates its respective major or minor release (in this case, 4.3) inclusive of all updates up to a certain point. See our [supported releases](https://doc.qubes-os.org/en/latest/user/downloading-installing-upgrading/supported-releases.html) for a comprehensive list of major and minor releases and our [version scheme](https://doc.qubes-os.org/en/latest/developer/releases/version-scheme.html) documentation for more information about how Qubes OS releases are versioned. \ No newline at end of file From 800123b201999412834fe30cf7b3f72e17689e5f Mon Sep 17 00:00:00 2001 From: Andrew David Wong Date: Thu, 11 Jun 2026 16:43:59 -0700 Subject: [PATCH 2/3] Specify post date --- ...-released.md => 2026-06-11-qubes-os-4-3-1-has-been-released.md | 0 1 file changed, 0 insertions(+), 0 deletions(-) rename 2026-06-XX-qubes-os-4-3-1-has-been-released.md => 2026-06-11-qubes-os-4-3-1-has-been-released.md (100%) diff --git a/2026-06-XX-qubes-os-4-3-1-has-been-released.md b/2026-06-11-qubes-os-4-3-1-has-been-released.md similarity index 100% rename from 2026-06-XX-qubes-os-4-3-1-has-been-released.md rename to 2026-06-11-qubes-os-4-3-1-has-been-released.md From ae0eac39e262072cbb2a3c255039e21273081f16 Mon Sep 17 00:00:00 2001 From: Andrew David Wong Date: Thu, 11 Jun 2026 16:47:39 -0700 Subject: [PATCH 3/3] Add reminder about Qubes OS User Survey 2026 --- 2026-06-11-qubes-os-4-3-1-has-been-released.md | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/2026-06-11-qubes-os-4-3-1-has-been-released.md b/2026-06-11-qubes-os-4-3-1-has-been-released.md index b666358..ae78a40 100644 --- a/2026-06-11-qubes-os-4-3-1-has-been-released.md +++ b/2026-06-11-qubes-os-4-3-1-has-been-released.md @@ -7,7 +7,11 @@ download_url: /downloads/ We're pleased to announce the stable release of Qubes OS 4.3.1!
