Breaking: `IAggregateRoot` has some breaking changes. If these methods aren't
used (which is considered the typical case), then the base class
`AggregateRoot<,,>` will automatically handle it
- `CommitAsync` has an additional `ISnapshotStore` parameter. If you don't
use snapshot aggregates, then you can safely pass `null`
- `LoadAsync` is a new method that lets the aggregate control how its
loaded fromt the event- and snapshot stores
New core feature:** EventFlow now support snapshot creation for aggregate
roots. The EventFlow documentation has been updated to include a guide on
how to get started using snapshots. Snapshots are basically an opt-in optimized
method for handling long-lived aggregate roots. Snapshot support in EventFlow
introduces several new elements, read the documentation to get an overview.
Currently EventFlow offers the following snapshot stores
- In-memory
- Microsoft SQL Server
New: The `IAggregateStore` is introduced, which provides a cleaner interface
for manipulating aggregate roots. The most important method is the
`UpdateAsync` which allows easy updates to aggregate roots without the need
for a command and command handler
- `LoadAsync`
- `UpdateAsync`
- `StoreAsync`
New: `IEventStore` now supports loading events from a specific version using
the new overload of `LoadEventsAsync` that takes a `fromEventSequenceNumber`
argument
New: `IMsSqlDatabaseMigrator` now has a overloaded method named
`MigrateDatabaseUsingScripts` that takes an `IEnumerable<SqlScript>`
enabling specific scripts to be used in a database migration
New: Added suport to use EventStore persistence with connection strings
instead IPs only
Obsolete: The following aggregate related methods on `IEventStore` has been
marked as obsolete in favor of the new `IAggregateStore`. The methods will be
removed at some point in the future
- `LoadAggregateAsync`
- `LoadAggregate`
