Why was the custom repository syntax changed?

Problem

I'm currently migrating from 0.2 to 0.3 and noticed that the syntax for custom repository was changed. I personally find this change very odd but I assume typeorm devs have a perfectly fine explanation for this - I lack to find it though. Remark: I know that this issue is not a documentation issue per se but SO is not the place to discuss things that's why I decided to post it here. Where I'm coming from: My project only uses a single relational database with various small custom repositories. Here is a simple example repository from 0.2: import {User} from "../bl/user"; import {EntityManager, EntityRepository, Repository} from "typeorm"; @EntityRepository(User) export class UserRepository extends Repository<User> { findByEmail(email: string): Promise<User | undefined> { // Implementation not relevant } isEmailAlreadyInUser(email: string): Promise<boolean> { // Implementation not relevant } } export function getUserRepository(manager: EntityManager): UserRepository { return manager.getCustomRepository(UserRepository); } New 0.3 version: // I have to manually create a type so UserRepository exists in type space. export type UserRepositoryType = Repository<User> & { findByEmail(email: string): Promise<User | null>; isEmailAlreadyInUser(email: string): Promise<boolean>; } // this UserRepository only exists in value space. Without my previous type
