 ## [Unreleased] - ReleaseDate
 
+> **Breaking Change Upgrade Note For Library Users**
+>
+> Due to the collapsing of a library crate and a binary/CLI crate into one
+> crate, there is now a Cargo feature called `"application"` which is included
+> in the default features. This allows for a clean `cargo install names`,
+> resulting in a compilation and installation of the names CLI without any
+> further options or flags. When using names as a library crate however, it is
+> advised to now add `default-features = false` to the crate dependency in
+> `Cargo.toml`. For example:
+>
+> ```toml
+> [dependencies]
+> names = { version = "0.12.0", default-features = false }
+> ```
+>
+> This will exclude the `clap` crate when being used in library/crate mode.
