How to return file back from the archive?

@dschinn-de, is there any update on removing archived files?

We have a built-in auto-update that is only designed to work with versions that are still actively in use. If a user downloads a very old version it may have unexpected side effects.

Previously when we tested this, the archived files were not available for download so there was no potential issue - but it seems access to archived files has been enabled since then. How can we remove access to download old versions to prevent potentially failed upgrades? Is it still impossible?
