Users should add their custom rules to the `custom-input` and `custom-forward` chains. (For more information, see issues [#5031](https://github.com/QubesOS/qubes-issues/issues/5031) and [#6062](https://github.com/QubesOS/qubes-issues/issues/6062).) Also see the [full list of open bug reports affecting Qubes 4.2](https://github.com/QubesOS/qubes-issues/issues?q=is%3Aissue+label%3Aaffects-4.2+label%3A%22T%3A+bug%22+is%3Aopen). We strongly recommend [updating Qubes OS](https://www.qubes-os.org/doc/how-to-update/) immediately after installation in order to apply all available bug fixes. ## How to get Qubes OS 4.2.0 - If you don't have Qubes OS installed, or if you're currently on Qubes 4.0 or earlier, follow the [installation guide](https://www.qubes-os.org/doc/installation-guide/). - If you're currently on Qubes 4.1, learn [how to upgrade to Qubes 4.2](https://www.qubes-os.org/doc/upgrade/4.2/). - If you're currently on a Qubes 4.2 release candidate (RC), [update normally](https://www.qubes-os.org/doc/how-to-update/). In all cases, we strongly recommend [making a full backup](https://www.qubes-os.org/doc/how-to-back-up-restore-and-migrate/) beforehand. ## Reminder: new release signing key for Qubes 4.2 As a reminder, we published the following special announcement in [Qubes Canary 032](https://www.qubes-os.org/news/2022/09/14/canary-032/) on 2022-09-14: > We plan to create a new Release Signing Key (RSK) for Qubes OS 4.2. Normally, > we have only one RSK for each major release. However, for the 4.2 release, we > will be using Qubes Builder version 2, which is a complete rewrite of the > Qubes Builder. Out of an abundance of caution, we would like to isolate the > build processes of the current stable 4.1 release and the upcoming 4.2 > release from each other at the cryptographic level in order to minimize the > risk of a vulnerability in one affecting the other. We are including this > notice as a canary special announcement since introducing a new RSK for a > minor release is an exception to our usual RSK management policy. As always, we encourage you to [authenticate](https://www.qubes-os.org/security/pack/#how-to-obtain-and-authenticate) this canary by [verifying its PGP signatures](https://www.qubes-os.org/security/verifying-signatures/). Specific instructions are also included in the [canary announcement](https://www.qubes-os.org/news/2022/09/14/canary-032/). As with all Qubes signing keys, we also encourage you to [authenticate](https://www.qubes-os.org/security/verifying-signatures/#how-to-import-and-authenticate-release-signing-keys) the new Qubes OS Release 4.2 Signing Key, which is available in the [Qubes Security Pack (qubes-secpack)](https://www.qubes-os.org/security/pack/) as well as on the [downloads](https://www.qubes-os.org/downloads/) page under the Qubes OS 4.2.0-rc5 ISO. ## Support for older releases In accordance with our [release support policy](https://www.qubes-os.org/doc/supported-releases/#qubes-os), Qubes 4.1 will remain supported for six months after the release of Qubes 4.2, until 2024-06-18. After that, Qubes 4.1 will no longer receive security updates or bug fixes. [Whonix templates](https://www.whonix.org/wiki/Qubes) are created and supported by our partner, the [Whonix Project](https://www.whonix.org/). The Whonix Project has set its own support policy for Whonix templates in Qubes. For more information, see [Qubes-Whonix version support policy](https://www.whonix.org/wiki/About#Qubes_Hosts). ## Thank you to our partners, donors, contributors, and testers! This release would not be possible without generous support from our [partners](https://www.qubes-os.org/partners/) and [donors](https://www.qubes-os.org/donate/), as well as [contributions](https://www.qubes-os.org/doc/contributing/) from our active community members, especially [bug reports](https://www.qubes-os.org/doc/issue-tracking/) from our [testers](https://www.qubes-os.org/doc/testing/).
