Gno: An interpreted, stack-based Go virtual machine to build succinct and composable apps + gno.land: a blockchain for timeless code and fair open-source.
We try only to add new extensions once they have some usage on GitHub. In most cases we prefer that each new file extension be in use in at least 200 unique :user/:repo repositories before supporting them in Linguist (but see https://github.com/github/linguist/issues/5756 for a temporary change in the criteria).
