# [2.0.0](https://github.com/strongloop/loopback-next/compare/@loopback/express@1.4.1...@loopback/express@2.0.0) (2020-09-15)


### Features

* move framework packages to `devDependencies` ([e2c61ce](https://github.com/strongloop/loopback-next/commit/e2c61ce79aa68d76f6e7138642034160b50063f0))


### BREAKING CHANGES

* components no longer install core framework packages as
their own dependencies, they use the framework packages provided by the
target application instead.

If you are getting `npm install` errors after upgrade, then make sure
your project lists all dependencies required by the extensions you are
using.
