Upgrading nannou

You can upgrade to a new version of nannou by editing your Cargo.toml file to use the new crate. For v0.12 use the line nannou = "0.12". Run

cargo update

inside the nannou directory to upgrade all dependencies.

Building Nannou examples might still fail. This is most likely due to new language features. Nannou 0.12 for example requires rustc 1.35.0. You can upgrade your (local) rust toolchain by executing

rustup update
