Quest has just posted the RTM version of AD cmdlets 1.1 (1.1.1 to be exact, 1.1.0 was a beta version out for the last couple of months).
Besides the wonderful new stuff which was there in the beta (security management is my personal favorite), there are other great improvements ranging from performance advances and bugfixes to a number of other scenarios for account manipulation, provisioning, and copying added (some re-introduced) in this latest drop. Also, AD cmdlets are now available both in 32- and 64-bit versions.
I will blog about them in details next week (when I am back from vacation) but for now you can look at the documentation, built-in help, and the changes txt document.
