Releases
==========
Please update your installation to the latest version 5.3.9.
This update includes significant changes to IP detection logic in conjunction
with the use of proxies. If using services such as CloudFlare, or any other
similar public or private proxy service, to proxy traffic to your WHMCS
installation, you will need to perform additional steps post upgrading in order
to keep IP detection functioning correctly. If in any doubt, we urge you to read
the Release Notes or contact our support team for further information prior to
updating.
The update includes a significant update to the low-level cryptographic routines
used for admin authentication. These changes will affect any 3rd-party
integration which directly accesses the admin user database table; should not
have an observable impact on installations otherwise. Further details can be
found in the Release Notes.
The update brings End Of Life for the Ensim server module as well as the E-Gold
and PayOffline gateway modules. Please read the Release Notes if you activity
using those modules.
