Refer to the following sections for details about the new features released in version 7.2.60.0.

ACME Wildcard Certificates and DNS Challenge

In previous releases, the ACME certificate feature only supported the HTTP-01 challenge when obtaining a new certificate. With this release, the ACME DNS-01 challenge is now supported. This allows customers to obtain wildcard certificates from supported ACME providers. For further details, refer to the Let's Encrypt and DigiCert Feature Descriptions on the Certificates documentation page.

Per-VS Parameters for Resource Based Adaptive Scheduling

In previous releases, the operational parameters for resource based adaptive scheduling could only be set globally – with the same parameters applying across all Virtual Services that have adaptive scheduling enabled.

With this release, the global settings can now be overridden by applying different settings on the Virtual Service. For further details, refer to the Standard Options section of the Web User Interface (WUI) Configuration Guide and search the page for Resource Based (Adaptive).

GEO Process Watchdog

A GEO process watchdog now continuously monitors the health of critical GEO processes. The monitor is enabled by default (as you can see on the Global Balancing > GEO System Info/Debug page; the watchdog process is the last one listed):

If the watchdog detects that one of the other services is not running, it attempts to restart it. This is reflected in the system log; for example:

logger: named is down
logger: A GEO process has failed, restarting GEO, attempt 1

Note that there is a Disable Process Monitor button on the page to disable the process monitor, but this should only be used when debugging GEO issues. The enabled/disabled state of the process monitor is synchronized between a High Availability pair, but is not synchronized between GEO partners.
