Cargo Features

[dependencies]
pallet-ibc = { version = "2.0.0-pre.2", default-features = false, features = ["std"] }
default = std

The std feature is set by default whenever pallet-ibc is added without default-features = false somewhere in the dependency tree.

std default = serde

Enables std of parity-scale-codec ^1.3.4, finality-grandpa ^0.12.3, frame-support ^2.0.0, frame-system ^2.0.0, hash-db ^0.15.2, sp-core ^2.0.0, sp-finality-grandpa ^2.0.0, sp-runtime ^2.0.0, sp-std ^2.0.0, and sp-trie ^2.0.0

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.
