# Authentication Provider OAuth Release 2.0
# New Features and Improvements
# Compatibility for 4App Core Engine version 4.2
This release adds compatibility with Core Engine 4.2 or higher. Core Engine versions below 4.2 must stick with the 4ALLPORTAL Authentication Provider OAuth version 1.
# Technical Changes & Admin Instructions
# 4App Authentication Base No Longer Required
We removed the dependency to 4App Authentication Base. Its functionality is included in 4App Core Engine from Core version 4.2.
What to do: Please remove 4App Authentication Base before you upgrade to 4App Core Engine 4.2 or ghigher. The existing configuration will still work.
# Solved Bugs
- Remove dependency on 4App Authentication Provider Ldap, which is not required for oAuth.
- Fix unsupported deep links to 4ALLPORTAL. For example, links to a specific module and view will now show the correct frontend page.
# How to Get these Improvements
- Upgrade 4App Authentication Provider OAuth to version 2.0
- Dependency: Upgrade 4App Core Engine to version 4.2 or higher
