PureOS 11 Crimson launches
Designed to be the best PureOS yet by Prism, the "Crimson" release replaces "Byzantium," and all devices that came with it will receive the update, including the earliest Librem 13 and 15 computers. This update focuses on fixes and optimizations, without adding any major features.

Privacy- and security-focused PureOS is back with release 11, codenamed "Crimson" and compatible with third-party devices as well as Librem laptops and smartphones, as well as Liberty Phone handsets. Sadly, this update doesn't come with any major new features, focusing on small improvements and fixes instead.

According to the official release notes, PureOS 11 will hit all devices currently running its predecessor, namely PureOS "Byzantium," and opens the way to its successor, which already has a name: "Dawn." These are the highlights mentioned in the release notes (the link can be found further down this page, in the Source section):

  • Reliability and stability improvements, including ironing out the crash that occurred when disconnecting external displays on the Librem 5 and Librem 11, as well as the hardware killswitch issues that plagued the Librem 5.
  • Several updates to metapackages, syncing them with Debian Bookworm.
  • Multiple improvements to the Librem 5 camera stack, as well as several bug fixes.
  • Automatic rotation of photos and videos to match the phone's orientation.
  • Photo postprocessing is now done using the GPU via OpenGL, which is more efficient than the phone's CPU.

Those who want to support this effort can choose to subscribe to PureOS, although the system remains free. The Standard, Premium, and Expert tiers are valued at $5.99, $9.99, and $19.99 per month. Various hardware devices, including the $2,999+ Librem Server, can also be found on the page detailing the subscription plans.

New users and those who want to reinstall the system can grab the ISOs from here.
