Has IE9 been offered through automatuc updates as yet?

I was told that MS would push through IE9 as an important update on 21st March but i haveyou been guys offered this update through win locker onupdates. I checked just now and there seems no sign of this to-date. Have you guys seen this update in auto updates(if you have it on)? Just want to be sure and so am checking with others on this forum. ....and no i do not have IE blocker or any reg entry on to prevent the same

so i would have to download and install it myself?
and it will NEVER be intimated to me via auto update?

for BETA build,you need to go to Microsoft and download the installer to upgrade to RTM build
for RC build,windows update will offer you the RTM build IE9,you and simply upgrade it through windows update.
