 //!
-//! Lightning nodes advertise a supported set of operation through feature flags. Features are
-//! applicable for a specific context as indicated in some [messages]. [`Features`] encapsulates
-//! behavior for specifying and checking feature flags for a particular context. Each feature is
-//! defined internally by a trait specifying the corresponding flags (i.e., even and odd bits).
+//! See [`lightning_types::features`] for the list of features currently supported.
 //!
 //!
-//! Whether a feature is considered \"known\" or \"unknown\" is relative to the implementation, whereas
-//! the term \"supports\" is used in reference to a particular set of [`Features`]. That is, a node
-//! supports a feature if it advertises the feature (as either required or optional) to its peers.
-//! And the implementation can interpret a feature if the feature is known to it.
+//! Note that the use of types via this module is deprecated and will be removed in a future
+//! version. Instead, use feature objects via [`lightning::types::features`].
