anchor.diff:  * An observer for `@Initialized(ConversationScoped.class)` or `@Destroyed(ConversationScoped.class)` event no longer forces eager conversation context initialization. See also <<_lazy_and_eager_conversation_context_initialization>>.
   
   * `ScheduledExecutorServiceFactory` is deprecated and no default implementation is provided by default. This service has not been used by Weld internals at least since version 1.1.0.Final.
  +
  +==== Migration from Weld 2.3 to 2.4
  +
  +* Weld does not depend on `com.google.guava:guava` anymore. The dependency is also not bundled with shaded artifacts for Weld SE and Weld Servlet.
  +
  +* A wildcard type is not considered an unresolvable type variable - this reflects the output of a clarification issue https://issues.jboss.org/browse/CDI-494[CDI-494].
  +
  +* Deprecated `org.jboss.weld.resources.SingleThreadScheduledExecutorServiceFactory` was removed.
  +
  +* Weld SE:
  +
  +** Deprecated `org.jboss.weld.environment.se.beans.InstanceManager` was removed.
  +
  +** Deprecated `org.jboss.weld.environment.se.ShutdownManager` was removed.
  +
  +** Deprecated `org.jboss.weld.environment.se.contexts.interceptors.ActivateThreadScope` was removed.
  
positive.code: The `org.jboss.weld.bootstrap.api.Bootstrap` interface defines the
  initialization for Weld, bean deployment and bean validation. To boot
  Weld, you must create an instance of
  `org.jboss.weld.bootstrap.WeldBootstrap` which implements 
  `org.jboss.weld.bootstrap.api.CDI11Bootstrap` which extends the above mentioned
  `Bootstrap`. Then you need to tell it about the services in use, and finally request the
  container start.
  
negative.code: `@PersistenceContext` for injection into managed beans (with the
  `InjectionPoint` provided), is delegated to the container.
  
  To allow JPA integration, the `org.jboss.weld.injection.spi.JpaInjectionServices` interface
  should be implemented. This service is not required if the implementation of
  <<_injection_services>> takes care of `@PersistenceContext` injection.
