# List of notable changes made between 2.x and 3.0
|
|
|
|
All breaking changes must be described here. When adding a new entry,
|
|
always describe the impact on users and instructions for upgrading
|
|
applications from 2.x to 3.0.
|
|
|
|
## loopback-datasource-juggler was moved from peerDependencies to dependencies
|
|
|
|
Originally, we (ab)used peer dependencies to ensure there is only one instance
|
|
of loopback-datasource-juggler in the dependency tree, so that there is only
|
|
one singleton instance of model registry. This was very fragile and might not
|
|
have worked in certain edge cases.
|
|
|
|
We have reworked loopback-datasource-juggler and connectors to not rely on
|
|
a single juggler instance anymore. As the last step, juggler became a regular
|
|
dependency.

|
|
|
|
When upgrading application from previous loopback versions, simply remove
|
|
loopback-datasource-juggler from your dependencies.

|
## always use bluebird as promise library
|
|
|
|
In version 3.0, we always use bluebird as our promise library
|
|
instead of `global.Promise`.
|
|
We consider Bluebird API a part of LoopBack API from now on,
|
|
you are welcome to use any Bluebird-specific methods in your applications.
|
|
|
|
If you are using LoopBack with a custom promise implementation provided
|
|
via `global.Promise`,
|
|
you will have to check all places where you are using non-standard promise API
|
|
and update them to use Bluebird API instead.
