### BREAKING CHANGES

* **core:** `em.getReference()` now has options parameter.
* Most of the methods on IDatabaseDriver interface now have different signature.
* **core:** `SchemaGenerator` API changed, boolean parameters are now removed
in favour of options objects

```ts
interface SchemaGenerator {
  generate(): Promise<string>;
  createSchema(options?: { wrap?: boolean }): Promise<void>;
  ensureDatabase(): Promise<void>;
  getCreateSchemaSQL(options?: { wrap?: boolean }): Promise<string>;
  dropSchema(options?: { wrap?: boolean; dropMigrationsTable?: boolean; dropDb?: boolean }): Promise<void>;
  getDropSchemaSQL(options?: { wrap?: boolean; dropMigrationsTable?: boolean }): Promise<string>;
  updateSchema(options?: { wrap?: boolean; safe?: boolean; dropDb?: boolean; dropTables?: boolean }): Promise<void>;
  getUpdateSchemaSQL(options?: { wrap?: boolean; safe?: boolean; dropDb?: boolean; dropTables?: boolean }): Promise<string>;
  createDatabase(name: string): Promise<void>;
  dropDatabase(name: string): Promise<void>;
  execute(sql: string, options?: { wrap?: boolean }): Promise<void>;
}
```
* **sql:** - `em.transactional()` signature has changed, the parameter is now options object
- `em.begin()` signature has changed, the parameter is now options object
