 - Add `#[schemars(inner(...)]` attribute to specify schema for array items (https://github.com/GREsau/schemars/pull/234)
 
+### Changed:
+
+- New optional associated function on `JsonSchema` trait: `schema_id()`, which is similar to `schema_name()`, but does not have to be human-readable, and defaults to the type name including module path. This allows schemars to differentiate between types with the same name in different modules/crates (https://github.com/GREsau/schemars/issues/62 / https://github.com/GREsau/schemars/pull/247)
+
 ### Fixed:
 
 - Schemas for `rust_decimal::Decimal` and `bigdecimal::BigDecimal` now match how those types are serialized by default, i.e. as numeric strings (https://github.com/GREsau/schemars/pull/248)
