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