The GitHub Arctic Code Vault
The GitHub Arctic Code Vault is a data repository preserved in the Arctic World Archive (AWA), a very-long-term archival facility 250 meters deep in the permafrost of an Arctic mountain. The archive is located in a decommissioned coal mine in the Svalbard archipelago, closer to the North Pole than the Arctic Circle. GitHub will capture a snapshot of every active public repository on 02/02/2020 and preserve that data in the Arctic Code Vault.
So it makes sense to make a releases of your libraries and tools before
