- Added pre-parse text transformations for query arguments to normalize raw query strings before parsing, closing HTTP parameter pollution gaps.
- Introduced ten new text transformations (e.g., Uppercase, Trim, Remove Whitespace, SHA256, OS‑aware command line/JS decoding) that can be chained up to ten per rule statement.
- Transformations cost 10 WCUs each, incur no extra charge beyond standard pricing, and are available in all AWS regions with documentation links.
