I just noticed that two deprecated plugins of mine, neither of which has any non-hidden versions, got new downloads recently. The first was downloaded on the 10th and 13th (also the 11th for the latest version), while the second only the 13th; there is only one unique download per day. This happens to other plugins as well, though their versions are not hidden.
Was this an intentional action performed by JetBrains?
I’m sorry for keeping you waiting on this! We are still investigating this, and it appears to be related to downloads from custom plugin repositories. As soon as we have more concrete details about the nature of this, I will provide a further update.
