The Delicious service launched a preliminary version of its website version 2.0, which is available only by invitation. You can read it at 
preview.delicious.com .
In addition, the service re-branded the name and site (it was 
del.icio.us , it became just 
delicious , although this address still leads to the old site).
Bookmarks of users who received invitations are imported to a new resource, although developers warn that after launching the final version, the imported bookmarks will be lost. In other words, 
preview.delicious.com offers users to evaluate the new interface and new features of the service, no more.
Also, according to the developers, the new version completely rewritten the code.

PS How to get an invite. The user of the service should go to a special 
section , leave a request for an invite, and then wait for the administration to send him a link to the “links for you” section.
