We now make sure that type expressions cannot be used in SpEL expressions handled by MapDataBinder. They're gonna be rejected by considering the property not writable. SpEL expression evaluation errors are now forwarded as NotWritablePropertyException to make sure the failure gets handled as if the property referred to doesn't exist.
If a query method now uses e.g. a Vavr Set as return type, we now also use a potential source List as input for the LinkedHashSet, even if that changes the characteristics (duplicate policy etc.) of the result. This is consistent with our general handling of collections as we're using a Spring ConversionService for collection mapping anyway.
In general the new conversion algorithm is driven by the expected target type first:
- i.v.c.Seq -> i.v.c.List
- i.v.c.Set -> i.v.c.LinkedHashSet
- i.v.c.Map -> i.v.c.LinkedHashMap
If none of the declared types is assignable we fall back to the previous algorithm choosing an implementation as close as possible to the original source value:
- j.u.List -> i.v.c.List
- j.u.Set -> i.v.c.LinkedHashSet
- j.u.Map -> i.v.c.LinkedHashMap
Applied the same fixes to the deprecated Javaslang support. Removed some obsolete full qualifications of types.
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.
