Noteworthy changes in 0.10.0

  • Adjust media previews and optimize memory footprint
  • Implement sharing profile attribute and profile picture with contacts
  • Fix several UI issues and memory leaks
  • Improve UI to waste less vertical space for smaller screens

Known Issues

  • Chats still require a reliable connection between GNUnet peers. So this still depends on the upcoming NAT traversal to be used outside of local networks for most users (see #5710).
  • File sharing via the FS service should work in a GNUnet single-user setup but a multi-user setup breaks it (see #7355)
