# Migrate from Pre-1.0 Releases

Version 1.0 is a major release of Authcore that contains many improvements and new features. As it contains several changes that are incompatible with previous releases, developers are required to change their apps before upgrading to Version 1.0.

## Major Changes in Authcore 1.0

### API 2.0

API 2.0 is a complete revamp of Authcore API. It is a RESTful API with a simpler and more consistent design. Previous gRPC-based API was deprecated.
