Changes:
This release fixes a number of major and minor
bugs, some of which are critical and may cause
crashes under some conditions. A new module,
m_ldapauth, is also included for authenticating
against an LDAP directory server. This module was
based on the module written for the (now defunct)
Unreal 4, with a few changes to make it more
secure. This is a highly recommended release.
