I cannot find fastgrowcut extension in latest version 4.11.

I just installed latest 3d slicer version 4.11, but cannot find fastgrocut extension.
Is ‘‘fastgrowcut’’ extension deleted from the latest version?
I am using mac version.
Thank you for your help!

The extension is still present in the index, but is currently failing to build on all platforms.

It appears to have been broken when a legacy function was removed from ITK:
error: ‘class itk::TimeProbe’ has no member named ‘GetMeanTime’

The old fastgrowcut extension has been completely reworked, hugely improved in performance, robustness, and usability, and the result has been made available in Segment editor module as “Grow from seeds” effect. You can find several tutorials about how to use it on the training page.
