Breaking: Aggregate root no longer have `Aggregate` removed from their
when name, i.e., the metadata property with key `aggregate_name` (or
`MetadataKeys.AggregateName`). If you are dependent on the previous naming,
use the new `AggregateName` attribute and apply it to your aggregates
Breaking: Moved `Identity<>` and `IIdentity` from the `EventFlow.Aggregates`
namespace to `EventFlow.Core` as the identities are not specific for aggregates
Breaking: `ICommand.Id` is renamed to `ICommand.AggregateId` to make "room"
for the new `ICommand.SourceId` property. If commands are serialized, then
it _might_ be important verify that the serialization still works. EventFlow
_does not_ serialize commands, so no mitigation is provided. If the
`Command<,>` is used, make sure to use the correct protected constructor
Breaking: `IEventStore.StoreAsync(...)` now requires an additional
`ISourceId` argument. To create a random one, use `SourceId.New`, but it
should be e.g. the command ID that resulted in the events. Note, this method
isn't typically used by developers
New: Added `ICommand.SourceId`, which contains the ID of the source. The
default (if your commands inherit from `Command<,>`) will be a new
`CommandId` each time the a `Command<,>` instance is created. You can pass
specific value, merely use the newly added constructor taking the ID.
Alternatively you commands could inherit from the new
`DistinctCommand`, enabling commands with the same state to have the
same `SourceId`
New: Duplicate commands can be detected using the new `ISourceId`. Read the
EventFlow article regarding commands for more details
New: Aggregate names can now be configured using the attribute
`AggregateName`. The name can be accessed using the new `IAggregateRoot.Name`
property
New: Added `Identity<>.NewDeterministic(Guid, string)` enabling creation of
[deterministic GUIDs](http://code.logos.com/blog/2011/04/generating_a_deterministic_guid.html)
New: Added new metadata key `source_id` (`MetadataKeys.SourceId`) containing
the source ID, typically the ID of the command from which the event
originated
New: Added new metadata key `event_id` (`MetadataKeys.EventId`) containing a
deterministic ID for the event. Events with the same aggregate sequence
number and from aggregates with the same identity, will have the same event
identity
Fixed: `Identity<>.With(string)` now throws an `ArgumentException` instead of
a `TargetInvocationException` when passed an invalid identity
Fixed: Aggregate roots now build the cache of `Apply` methods once, instead
of when the method is requested the first time
