Deserializer customizations for related resources (deserializing an instance from a URI) are not applied to the creator properties Jackson uses to create an entity instance in the first place (see [0] for details). We work around this now by tweaking the property instances used for that in their origin ValueInstantiator via reflection until the bug gets fixed.

Removed the redeclaration of hasCorsConfigurationSource(…) in RepositoryRestHandlerMapping as it already inherits the one from BasePathAwareRestHandlerMapping.
Removed @Override on BasePathAwareRestHandlerMapping.hasCorsConfigurationSource(…) as we need to compile against Spring 5.1, which doesn't expose the method. Downgrades from Spring HATEOAS 1.0 API usage in tests.
We now enable CORS handling for all requests by overriding the newly introduced hasCorsConfigurationSource method. We cannot detect CORS configuration handling solely on the handler but require path headers to resolve repository interface mappings.
Contrary to what's stated in the Javadoc of BackendIdConverter, BackendIdConverterHandlerMethodArgumentResolver now skips the invocation of ….fromRequestId(…) if no identifier path variable is found for the mapping of the method invoked.
MappedProperties now immediately drops non-writable properties when created for deserialization. Previously those properties would have to be annotated with @JsonProperty(access = Access.READ_ONLY) explicitly to avoid them being considered.
We now use a dedicated implementation of MessageSourceResolvable to avoid missing enum value translations actually causing exceptions. That also allows us to defer the calculation of the default (potentially translated in a default way).
We're now able to correctly identify Map keys within JsonPatch paths so that e.g. people/Dave/name properly translates into a people['Dave'].name SpEL expression.
Streamlined the design of SpelPath to avoid duplicate parsing and properly express the difference between typed and untyped paths in the type hierarchy. Slightly refactored the type hierarchy so that only methods that make sense in either untyped or typed state appear on the instance returned (getLeafType(Class) was exposed on TypedSpelPath before, which was confusing).
The lookup of the RequestMappingInfo in exposeEffectiveLookupPathKey(…) yields null for CORS preflight requests to resources that do not support OPTIONAL explicitly. We now guard against that to avoid a subsequent NullPointerException.
Previously we assumed lookup types to always result in String based values. We now loosen that constraint to also allow other scalar types, mostly targeting numeric types like long and integer.
Aligned with general request attribute naming conventions and prefixed the one we now use with the class' name. Altered the local attribute name to EFFECTIVE_REPOSITORY_RESOURCE_LOOKUP_PATH.
Renamed the constant holding the name from …_KEY to …_ATTRIBUTE.
We now expose a partially resolved PathPattern to contain the explicit repository base path so that the subpaths can be grouped around the individual repositories exposed.

MappedProperties now exposes a factory method that uses the Jackson introspector for serialization (instead of deserialization) which now also includes read-only properties. Previously, read-only ones were not considered as they are excluded from the metadata if it is looked up for deserialization.
We now support adding a to a collection via JsonPatch expressions by using the collection's size as target index. Contrary to paths pointing to existing collection elements we cannot determine the type of the object to be created. Thus, we fall back to the common element type of all existing collection elements. We also reject indexes pointing to elements with an index greater than the current collection's size.
DomainObjectReader now aborts the recursive merges in case it encounters an entity that's described as @Immutable (just introduced in Spring Data Commons).
Fixed some generics and removed DomainObjectMerger as it's unused.
