CalyxOS is back
[Posted July 2, 2026 by jzb]
In August 2025, the CalyxOS privacy-focused<br>Android distribution announced<br>that it was pausing all releases while it reworked its<br>release process, security protocols, and changed its signing keys<br>following the departure of one of its founders. The project has now announced<br>that it is "officially back from the hiatus" with the<br>7.2.2.0 release.
CalyxOS 7.2.2.0 is signed by us using a new<br>HSM-based, open-source signing solution we designed to enhance the<br>security of the entire signing process, ensure redundancy, and remove<br>single points of failure. You can verify CalyxOS 7.2.2.0 and future<br>builds following these<br>instructions. For anyone who is interested, the security audit<br>report of the HSM provisioning ceremony script can be found here.
In addition, we also went through significant infrastructure<br>improvements. In particular, we have set up a cleaner server structure<br>to streamline each release. In response to Google's less frequent AOSP<br>source code releases, our team developed scripts to reduce the<br>overhead in applying monthly patches and updates. Please keep in mind,<br>additional manual steps are still needed to compensate for AOSP<br>changes, such as requesting and storing kernel sources with each<br>update. Currently, our lead engineer is continuing the maintenance of<br>the base device trees for both LineageOS and CalyxOS to bridge the gap<br>created by the absence of Google Pixel device trees.
