From 6d7c653b64a48aa80486f87907418992dd63d49b Mon Sep 17 00:00:00 2001 From: "Tobin C. Harding" Date: Mon, 14 Aug 2023 14:54:00 +1000 Subject: [PATCH 1/2] Use hashes instead of bitcoin_hashes Use the more terse `hashes` by way of the `package` field in the manifest. Allows us to remove the ugly feature alias "bitcoin-hashes" -> "bitcoin_hashes" and removes all the bother with the underscore.
