## AI overview

Mobian will not support Debian Bullseye after its release and will focus development on Debian bookworm. Bullseye users will continue receiving Debian core security updates and minor system-package upgrades, but not Mobian-maintained package security updates, new features, or usability improvements.

## Source excerpt

As you might be aware, the next Debian stable release (codename bullseye) is only a few days away. But what does it imply for Mobian? Bullseye on mobile Bullseye will be the first Debian release including a modern software stack aimed at mobile devices, which is an important milestone in itself. However, development in this area is progressing at a rapid pace, and most packages in bullseye are already outdated, missing important features such as improved modem handling during suspend/resume cycles, or recent packages like GTK4 and libadwaita. As Mobian is developed by a small team of already busy individuals, we have decided we wouldn't support bullseye after it's released and will focus our efforts on the next Debian version (codename bookworm). Current users will still get updates from Debian throughout the lifetime of bullseye but shouldn't expect new versions of user-facing applications or the mobile software stack. To put it short, here's what you'll get from sticking to bullseye: security updates for the core system minor upgrades to system packages Here's what you won't get should you decide to stick to bullseye: security updates for packages maintained by Mobian shiny new features usability improvements The way forward Within a few days, following the bullseye release, we'll create and populate a new Mobian repository targeting bookworm. Upgrading from bullseye to bookworm won't be automated and will require editing your sources.list files: simply replace bullseye with bookworm in both /etc/apt/sources.list and /etc/apt/sources.list.d/mobian.list. Notes: if you originally flashed your device with an image older than April 26th, 2021, will have to edit /etc/apt/sources.list.d/extrepo_mobian.sources, replacing Suites: mobian with Suites: bookworm if you were using Mobian staging so far, you will only need to edit /etc/apt/sources.list: our current staging repo will keep being the entry point for all new and updated packages we upload Please keep in mind that w
