     Currently, this is used to update default property mappings, and mark tokens and users generated by outposts.
 
+- Improved support for different LDAP Servers
+
+    The LDAP source has improved support for non-Active Directory LDAP setups. This includes the following changes:
+
+    - Switch to sync membership from groups to users rather than user to group
+    - Fix users, which were removed from a group in LDAP not being removed from said group
+    - Add support for LDAP servers which have core fields declared as lists
+    - Add property-mappings for groups, to map attributes like `name` or `is_superuser`
+
+- Add test view to debug property-mappings.
+
