Versions
By default the gtk crate provides only GTK+ 3.14 APIs. You can access more
modern APIs by selecting one of the following features: v3_16, v3_18, v3_20, v3_22, v3_24, v3_26, v3_28, v3_30.
Cargo.toml example:
[dependencies.gtk]
version = "0.1.0"
features = ["v3_16"]
Take care when choosing the version to target: some of your users might not have easy access to the latest ones. The higher the version, the fewer users will have it installed.
