What this post added

This post details the migration of Cloudflare's Bot Management heuristics engine from a Lua-based openresty implementation to the Cloudflare Ruleset Engine. This migration enables more expressive and precise rule writing, improving bot detection accuracy and reducing false positives. It also provides Bot Management customers with enhanced visibility through Bot Detection IDs, allowing for granular control and analysis of bot traffic in analytics, logs, and firewall events. New detection IDs for account takeover prevention have also been introduced.
