Removals, deprecations or backwards incompatible changes

Deprecations

• Deprecates usage of Calendar, Date, Time, Timestamp, Temporal, MapKeyTemporal and TemporalType
  in new applications in favour of java.time API
• Deprecates multiselect methods in CriteriaQuery. The preference is to use array or tuple method defined in CriteriaBuilder
• Deprecates use of Byte[] and Character[] arrays types for basic attributes, in favor of primitive array types

Deprecations for removal

• Deprecates addSubclassSubgraph() in EntityGraph for removal; addTreatedSubgraph() method should be used as direct replacement
• Deprecates addSubgraph(Attribute, Class) and addKeySubgraph() in Graph/EntityGraph/SubGraph for removal; addTreatedSubgraph(Attribute, Class)
  and addMapKeySubgraph() methods should be used as direct replacements
• Deprecates jakarta.persistence.spi.PersistenceUnitTransactionType for removal; jakarta.persistence.PersistenceUnitTransactionType
  methods should be used as direct replacement
• Deprecates default public no-arg constructor in jakarta.persistence.Persistence and PERSISTENCE_PROVIDER and providers fields
  in this class for removal with no replacement. This class is not designed for extensibility
