September 2025 – miraheze/puppet: Implemented Dynamic PowerDNS Recursor Configuration via Hiera, enabling the DNS resolver configuration to be pulled from Hiera data and applied per environment. This centralizes management of query-local-address and forward-zones, reduces manual configuration drift, and accelerates provisioning across environments. No major bugs fixed this month for this repo; work focused on feature delivery and code quality. Technologies demonstrated include Puppet, Hiera, and PowerDNS configuration management, with the commit 9fcc616ad57b886b7200afebd706b45521709739.
