I seem to have lost the NetScaler 15.1 download link (or permissions to it...). I can't figure out where to download the latest version on the site anymore - my on prem test instance is way back on 1.58nc Anyone else able to see it? citrix.com/downloads/citrix-adc/firmware/release-15-1-tech-preview.html

They took it down, probably because they didn't have an update for today's patches.
