v2.2.0

• Add reconstituteSequenceNumber() to AggregateRootBehavior to allow applying a persisted sequence number.
• Update Composer package metadata (keywords).

v2.1.0

• Remove SnapshotData::toJson() serialization belongs to adapters.
• Move SnapshotData from Event/ to Snapshot/ namespace.
• Introduce ModelVersion as a distinct value object, modelVersion() now returns ModelVersion instead of SequenceNumber.
• Introduce snapshot state hook with default reflection, aggregates with infrastructure properties override it.
• Add EventRecord::of() factory with sensible defaults.

v2.0.0

• Move Revision from call site to DomainEvent via revision() method with default Revision::initial() in DomainEventBehavior trait.
• Default identityName() to 'id' in EntityBehavior, removing boilerplate for aggregates following the conventional property name.
• Replace manual class-name parsing in EventSourcingRootBehavior::applyEvent with EventRecord type accessor.
• Add explicit eventHandlers() registration on EventSourcingRoot with backwards-compatible fallback to the when<EventShortName> convention.
• Ship SnapshotEvery and SnapshotNever as built-in SnapshotCondition implementations.

v1.1.1

• Delegate EntityBehavior::identityEquals() to Identity::equals() (value-object equality) and adjust related Identity interfaces.
• Rename upcaster payload hook (doUpcast() → rewrite()), and rename snapshot state payload (data → payload) with corresponding test updates.
• Add an explicit failure path when an event-sourced aggregate is missing a when* handler (currently via a native exception), plus accompanying tests and docs/config updates.

v1.1.0

• Replaced IDENTITY / MODEL_VERSION constants with identityName() / modelVersion() methods across entity/aggregate behaviors and updated tests/docs accordingly.
• Made Revision, SequenceNumber, and EventType constructors private and added/expanded semantic factories (initial(), first(), of(), fromString()).
• Added Upcasters collection with chain() plus IntermediateEvent object-mapping support (via tiny-blocks/mapper) and new upcast chain tests.

v1.0.0

• Introduce core domain primitives in src/ (Entity/Identity, AggregateRoot variants, event records, snapshots, upcasting).
• Add comprehensive PHPUnit tests plus test fixture models under tests/.
• Add project tooling and automation (Composer scripts, PHPUnit/PHPStan/Infection config, GitHub workflows) and expand.
