What this post added

Introduced persistent actions for WAF rules to block repeat offenders for customizable durations, rate limiting for specific endpoints to prevent API abuse, and a Firewall API for programmatic control of WAF settings. Extended the Challenge page functionality to the broader Vercel Firewall. Highlighted instant rule propagation (300ms) and the integration of these features into the development workflow.
