I think this is basically a feature request, but do you think it would be possible to retain older versions of packages on Google Cloud Launcher?
This bit me recently when trying to launch another instance of Postgres and I realized that only 10.1 is available now. I had previously launched Bitnami 9.6 Postgres images and now I either need to build these manually or switch to a different vendor.
It appears that Google's own images of Postgres allow tracking back to previous maintenance tracks, so the marketplace supports it.
Any chance Bitnami can start doing this so I can continue to use your images without fear of being forced into an incompatible upgrade?
