 ### Changed
 
 - The `crosslink` make target has been updated to use the `go.opentelemetry.io/build-tools/crosslink` package. (#2886)
+- In the `go.opentelemetry.io/otel/sdk/instrumentation` package rename `Library` to `Scope` and alias `Library` as `Scope` (#2976)
 
 ### Removed
 
 - Support for go1.16. Support is now only for go1.17 and go1.18 (#2917)
 
+### Deprecated
+
+- The `Library` struct in the `go.opentelemetry.io/otel/sdk/instrumentation` package is deprecated.
+  Use the equivalent `Scope` struct instead. (#2977)
+- The `ReadOnlySpan.InstrumentationLibrary` method from the `go.opentelemetry.io/otel/sdk/trace` package is deprecated.
