Cargo Features

[dependencies]
ic-certification = { version = "2.6.0", default-features = false, features = ["serde", "serde_bytes"] }
default = serde, serde_bytes

These default features are set whenever ic-certification is added without default-features = false somewhere in the dependency tree.

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
