When merging collections on PATCH we now don't use the first collection item's type for all elements but inspect the values for each existing element found. When it comes to appending elements to the collection, wen now just stick to the declared component type as type hint for reading the provided value.
When copying the transient properties of an aggregate, we now try field based access first and fall back to accessor based copying in case both a setter and getter are exposed on the type.
Previously we always expected a field to be present which doesn't necessarily has to be the case.

Jacksons ObjectMapper.readerForUpdate(…) unfortunately doesn't handle nested objects properly. We already have a manual merge process in place for PATCH requests but tweaking that to also handle PUT requests gracefully caused more complexity than anticipated.
We now switched to an object based merge so that we can read in the source JSON structure into a new object and then merge the objects.

We now use a Map property's generic type information to make sure we convert both the key and the value into the declared types. Previously we just used Object if the source value to map was null. Object is still used as fallback for raw maps though.
We now make sure that an @Order annotation on annotated event handler methods are considered and the methods are invoked in the defined order.
Non-annotation-based event handlers don't suffer from the same problem as they're ApplicationListener instances directly so that the container will enforce the correct ordering in case @Order is used or Ordered is implemented.
Some cleanup in EventHandlerMethod.

We now allow sorting by properties of embedded objects. An embedded object is not linkable to a root object but embedded in the resource itself. If any part of the sort property path points to a linkable association, the whole sort property path is discarded silently and not used for sorting any further.

We now issue the user registration of Jackson modules before any of the default modules Spring Data registers get applied. Testing module registration seems to be rather difficult as Jackson doesn't actually expose API to do so. An issue [0] was filed for Jackson to improve on this.

Skip all merge logic if the source value is null. That frees all nested logic from handling with that case and us falling back to plain Jackson reading.
The array handling now also opts out if the source value is not a collection or array in the first place as it means we need to let Jackson override the value with the collection given to be deserialized.

We now interpret If-None-Match and If-Modified-Since headers on requests to resources backed by query methods returning a single instance only. This allows clients to optimize GET requests to those resources to save bandwidth.
Fixed broken equals(…) in ProjectionDefinition. Switched to iterating over Map's entry set instead of the keys. Made UriAwareHttpServletRequest static.
Some tiny refactorings in DomainObjectReader. We're now using TypeInformation instead of Class to preserve more generics information when it comes to deeper nesting.
Moved some code around in the unit tests.

We now support nested Sort properties considering Jackson mapping. Sort translation is optional and skipped if the domain class is not resolvable. Translation in the scope of a domain class maps property paths to apply sorting using embedded properties.
A sort string `nested-name` resolves to a property path `anotherWrap.embedded.name`.
class Aggregate {
@JsonUnwrapped
public UnwrapEmbedded anotherWrap;
}
class UnwrapEmbedded {
@JsonUnwrapped(prefix = "nested-")
public Embedded embedded;
}
class Embedded {
public String name;
}

We now don't prematurely drop fields that don't have a persistent property exposed in DomainObjectReader. Doing so dropped values for transient fields as the latter are not exposed as persistent property in the first place. We still skip any nested merging though.

The serializer for projection resources now also invokes ResourceProcessor instances registered for that particular projection.

Instead of replacing the HAL Browser's browser.html, take the existing one and alter it inside the build job. This ensures that future updates don't break so horribly.
Related to https://github.com/mikekelly/hal-browser/pull/89 which will provide an explicit token to match, instead of using the closing `</body>` tag.
We now explicitly manually merge array nodes that contain complex objects. Previously arrays would've been skipped and the subsequent Jackson update would wipe out all properties not contained in the original document even on PATCH requests.
Removed RepositoryRestConfiguration.addCorsMapping(…) as we currently don't have any other shortcut methods for configuration like this.
Tweaked the setup of (now Repository)CorsConfigurationAccessor to be created earlier so that we avoid recreation for every lookup. Introduced a NoOpStringValueResolver to be used by default so that we don't need to deal with the case of the resolver being null at the end of the call chain. Replaced constructor of RepositoryCorsConfigurationAccessor with corresponding Lombok annotation.
Updated reference documentation accordingly.
