Is Admin a dead / unmaintained project?

No full release, still at beta. No non-dev release for 6 years. No dev release for 3 years.

Many patches sitting in the issue cue for years with no commits, like this one https://www.drupal.org/node/1968508

Last commit was 4 years ago: https://www.drupal.org/node/480736/committers

Incompatibility issues with major projects like jQuery Update.

Is anyone actually maintaining this project?
