New blog post introducing the WIP Duranium project (immutable postmarketOS), some of its major features, and explaining why some design decisions were made.

> Either the new image works, or the system falls back to the previous one automatically. No partially-applied state. No debugging audio when you need to make a phone call and no fussing with a broken web browser when you just want to doomscroll cat photos. It also means developers can reproduce the exact state of a user's device, making it much easier to track down and fix issues.

New finance blog post is up, nerding out over the 2025 budget (plan vs. execution), and the budget for 2026.

The most exciting part is probably the q6voice rework and mainlining which will improve audio significantly for postmarketOS and other Linux Mobile distributions on a large number of QC devices.

A huge thanks to everybody who is supporting postmarketOS financially to make this possible!

The all-new "devel" blog is now live!

https://postmarketos.org/devel/

As postmarketOS developer, it can be hard to keep up with changes in workflows and tooling, and understanding why these changes were made. @newbyte had the idea to create a blog specifically for such developer-relevant changes and wrote the first blog post for it, about the basically unused pmbootstrap subcommands "lint" and "aportupgrade" being removed. Thanks for that and to @przmk for implementing this new blog in our homepage!
