Caches are classified into five categories:

1. *Released wrapper distributions:* Distributions and related version-specific caches corresponding to released versions (e.g., `4.6.2` or `8.0`).
+
Default retention for unused versions is 30 days.
2. *Snapshot wrapper distributions:* Distributions and related version-specific caches corresponding to snapshot versions (e.g. `7.6-20221130141522+0000`).
