What this post added

Introduces support for pull-based deployment in GitLab's Free tier, utilizing the GitLab agent for Kubernetes to automatically enact application changes. This enhances flexibility, security, scalability, and automation in cloud-native environments by allowing agents within clusters to pull changes, contrasting with push-based deployments that require opening firewalls and granting external CI/CD admin access.
