Change Notices

The following changes have been added to this release of GEO.


GEO Limit for IP Addresses in an FQDN is increased from 16 to 64

The number of supported IP addresses that you can assign to a single FQDN defined within GEO has been increased from 16 to 64 to provide improved scalability for modern DNS configurations, as well as a better configuration experience.

GEO HA Configuration Issues in AWS and Azure Cloud Platforms

In previous releases, when deploying GEO in an HA configuration on either the Azure or AWS public clouds, the cluster and mapping menu IP addresses didn't get updated when the standby system takes the master (or active) role. This required a manual change on the newly active LoadMaster to correct the mapping. This issue has been addressed and new guidelines for creating a GEO HA configurations have been added to the HA for Azure guide and the HA for AWS guide.
