The latest version of it project is elementary OS 5.1.2 “Hera”, which comes with updated packages, a new login screen and an onboarding app to guide new users to the available features.
“The newly redesigned login and lockscreen greeter looks and works better, but also fixes a lot problems that have been mentioned with the previous greeter, such as focus issues, HiDPI and localization issues.
The new design of the Hera version responds to feedback from users of the Juno version and adds some new features. It will always show user names for all users, it shows user backgrounds like cards, so you can find them easier especially those without avatars, notifies when Caps or Num Lock is enabled and has a very distinct 'Log In as Guest' screen when enabled.
The new Onboarding application brought by the Hera version introduces the basic functions to the users and helps them to perform some common tasks after the first connection to the operating system, such as the management of privacy settings. ”
