Following a rebranding from postmarketOS to Nura, the project has made progress on mobile telephony features. Developers have implemented an initial version of call audio routing for the Fairphone 5 and Motorola Edge 30, enabling basic call functionality in Nura edge.

The LineageOS Changelog 32 update introduces new browser-based flashing tools via WebUSB to simplify device installation for ADB, Fastboot, Amlogic, and Samsung Odin protocols. The release also features major updates to core applications, including a new image editor called Canvas and a redesigned Updater. Additionally, security patches from August 2025 to October 2026 have been merged across various branches.

The 2026100600 release for GrapheneOS includes the full October 2026 security patch level and updates for Pixel device firmware and HALs.

It also addresses a critical integer overflow bug in ZipFileRO.cpp.

The postmarketOS project has announced a re-evaluation of its device categorization, specifically defining a new 'main' category for devices intended for daily use. To qualify, devices must meet strict technical standards including UEFI booting, use of upstream kernels with minimal patching, and support for essential features like calls, SMS, and Wi-Fi. The initiative also requires dedicated maintainer teams of at least five people to ensure long-term stability and hardware CI integration.

The Nura Project has officially registered as a non-profit association (ASBL) in Belgium. This move allows the project to sign legal agreements, receive grants directly, and manage its own finances independently. The team chose the Belgian ASBL model over US or German alternatives to ensure better governance and avoid specific political or bureaucratic drawbacks.

Key changes include the introduction of web-based flashing via fastboot, adb, and Odin protocols, a migration of the issue tracker from GitLab to GitHub, and a revised security backporting approach to align with Google's Android 16 quarterly patch model.

Google is rolling out a new requirement starting in September 2026 that mandates apps be registered to identity-verified developers on certified Android devices. This affects all installation methods, including sideloading. LineageOS has confirmed that since they do not ship GMS or undergo Google Test Suite certification, they are not obligated to implement this verification gatekeeper.
