magnifier and others: come back? still alive?

magnifier and others: come back? still alive?


hello,
i'm completely new to jquery and ui, but i would really like to know
about magnifier and other widgets
please accept my apologizes in advance if i'm misunderstanding
---
if i go to the magnifier page in the docs at http://docs.jquery.com/UI/Magnifier
i see that the component is no longer part of jquery ui
but i can see that many widegets are not included in the download
version 1.5 while they actually are in the 1.6rc version; among these
there is magnifier...
it seems that magnifier was part of jquery ui in the past, no longer
in the 1.5, and has come back (together with others) in the 1.6rc...
is it so? could you kindly explain the exact situation? may i rely on
magnifier and other widgets in the future? will docs come back for
these elements?
thank you very much for your help
