# Authentication Provider LDAP Release 5.0
# New Features and Improvements
# Compatibility for 4App Core Engine version 4.0
This release adds compatibility with Core Engine 4.0. Core Engine versions below 4.0 must stick with the 4ALLPORTAL Authentication Provider LDAP version 4.
# Technical Changes & Admin Instructions
# 4App Authentication Base No Longer Required
We removed the dependency to 4App Authentication Base. The functionality is included in 4App Core Engine from version 4.0.
