There is a an Gateway Management update available for testing:

yum update app-gateway* --disablerepo=* --enablerepo=clearos-contribs*

It gives one warning on upgrade

Failed to get unit file state for adamone.service: No such file or directory

This can be ignored.

From the developers:

Here’s the changes since the last version I sent:

Fix startup issues by migrating to systemd.
Fix an issue with disabling the service.

Previous changes include:

Allow using multiple DNS servers together
Improved reliability and responsiveness of schedules
Many other bugfixes and performance improvements

For me, a major thing it fixes in support is a regular core dump under some conditions.

Please post any issues found to this thread.
