We now prevent the superfluous creation of a MethodParameter and TypeDescriptor instance in repository method execution in case the value to be returned already is an instance of the expected method return type.
In CustomRepositoryImplementationDetector, we now immediately hand the Environment to the constructor of ClassPathScanningCandidateComponentProvider instead of setting it afterwards. This prevents a default StandardEnvironment from being created in the previously used constructor.
We now deploy a custom BeanPostProcessor to customize RequestMappingHandlerAdapter instances by prepending a ProxyingHandlerMethodArgumentResolver (requiring a @ModelAttribute) to the list of resolved HandlerMethodArgumentResolvers to make sure the settings defined in the annotation are applied but the projecting way of data binding is still used.
Introduced RepositoryFactorySupport.getProjectionFactory(…) to create a ProjectionFactory to be used for repository instances created. The default implementation uses the SpelAwareProxyProjectionFactory.
The ProjectionInformation implementation is now a named class so it can be used for more specialized implementations.

Previously, a call to AbstractMappingContext.getPersistentEntity(PersistentProperty) would've added potentially leniently added the type of the given PersistentProperty, no matter whether it's actually considered to be an entity in the first place. We now defensively check for whether the given property is to be considered an entity (taking potentially registered converters into account) before the potentially entity-creating by-type lookup.
We now eagerly resolve a generics declaration chain, which we previously - erroneously - expected GenericTypeResolver to do for us. Simplified TypeVariableTypeInformation implementation. Renamed ParameterizedTypeUnitTests to ParameterizedTypeInformationUnitTests.
Previously, the publication of the event that indicated a PersistentEntity having been added to it took place before the write lock over the entities had been released. We now keep the lock smaller and publish the addition event *after* the lock has been released.
Tweaked newly introduced RepositoryConfiguration.getImplementationBasePackage() to not require a parameter but use internal information instead (the repository interface in DefaultRepositoryConfiguration).

Custom repository implementation scan uses the repository interface package and its subpackages and no longer scans all configured base packages. Scan for fragment implementations defaults to the fragment interface package. Using the interface package for scanning aligns the behavior with the documentation.
Declaring the implementation along with the interface in the same package is an established design pattern allowing to limit the scanning scope. A limited scope improves scanning performance as it can skip elements on the classpath, that do not provide that particular package.
Previously, we scanned for implementations using the configured base packages that were also used to discover repository interfaces. These base packages can be broader for applications that spread repository interfaces across multiple packages.

When trying to determine if a parameter is a dynamic projection parameter, i.e. the parameter of type Class that determines the projection to use, now the type parameter of that method parameter gets compared with the unwrapped return type. Therefore this works now not only for Maps and Collections but also for the various wrappers defined in QueryExecutionConverters.
Moved the method for unwrapping the return type from AbstractRepositoryMetadata to QueryExecutionConverters in order to make it available to every class needing it. This also puts it closer to the data it is working on.

We now prefer to inspect the arguments handed to save(…) methods over inspecting the return value as the invocation of the actual method is free to exchange the instance handed into it and return a completely new one with the events contained in the parameter completely wiped.
We're now trying to look up a uniquely available ObjectMapper instance from the application context falling back to a simple new instance in case none can be found.
We now define generated PropertyAccessor classes using the entities' protection domain. Reusing the same protection domain preserves the same security and visibility rules as if the class was shipped within the source of the class loaded and prevents SecurityExceptions caused by signature certificate mismatch.
Previously we uses the protection domain of the PersistentEntity class implementation. This mismatch caused SecurityExceptions if the JAR file of the PersistentEntity was signed but not the JAR file where the domain class resides.

If a JSONPath expression is using a path not available in the backing payload we now return null rather than letting the PathNotFoundException propagate.
Methods for domain event registration and access are now not following bean semantics anymore to avoid those accidentally leaking into formats that use the bean spec (e.g. Jackson to produce JSON).
Deprecated old accessor methods and temporarily add @JsonIgnore to the method to avoid leakage but keep signatures intact.
We're now favoring the generic TypeInformation over trying to resolve the property type via field or PropertyDescriptor as only the former does proper generic type resolution.
Type specialization - i.e. enrichment of a raw type with a current generic context - is now only done if the current type is not yet resolved completely. This allows wildcarded target references to just fall back to the type to specialize, which will then by definition carry more generics information than the one to be specialized.
Revert the merging of a parent type's type variable map and only apply the locally available declared generics in case of parameterized types. Moved that augmentation into ParameterizedTypeInformation.
XmlBeam 1.4.11 accidentally removed ProjectionFactory as public interface. Adapted our HttpMessageConverter implementation to make sure we still work on those versions.
