pfSense Gold is a subscription service which provides a number of benefits to its clients, such as additional documentation and a secure and on-line backup service (called AutoConfigBackup or ACB). These and other components of the pfSense Gold service will soon be made available to pfSense users for free. "You may be wondering why we made this change, and why now? The pfSense book and the monthly pfSense Hangouts have proven valuable to many over the years. We decided to open them up to all for free. This brings us to ACB. We’ve always believed ACB is useful, and that everyone should have it. But, the resource usage required by the package design meant we had to pass some costs onto users. Earlier this year, the Netgate development team rewrote ACB - enabling us to make it available for free. Additionally, while the legacy package version relied on a username/password and a hostname, the new integrated ACB conforms to GDPR best practices. No private information at all is passed to ACB servers." More information on the change can be found in this blog post.
