No worries, please let us know if you see anything that's off on the sort though. :)
Please advise which project doesn't appear to be sorting in the correct way so we can investigate closer :)
I've worked with the developers and can confirm that the underlying implementations on the old site and the new site is the same.
If you can help me understand what you're seeing that looks off it'll help me escalate this further.
Speaking to the dev team the "Last Released File" sort option is functionally the same to "Last Updated" on the old site. We will be updating the label to make it clearer in the near future. :)
We have last released file as a sort option. Will get it reviewed, and see what's up. :)
