UUSEC Technology e66cca6014 v7.0.0
### Feature Updates

**Interface & Management**

- Redesigned main program and management interface with improved aesthetics and usability, supports UI language switching (English/Chinese)
- Added Rule Collections functionality: Create custom rule templates for batch configuration
- Introduced whitelist rules that terminate further rule matching upon success
- UUSEC WAF Rules API intelligent suggestions during advanced rule editing:ml-citation
- New plugin management supporting hot-reloaded plugins to extend WAF capabilities

**Protocol & Optimization**

- Supports streaming responses for continuous data push (e.g., LLM stream outputs)
- Enables Host header modification during proxying for upstream service access
- Search engine validation: `waf.searchEngineValid(dns,ip,ua)` prevents high-frequency rules from affecting SEO indexing
- Interception log report generation (HTML/PDF exports)
- Automatic rotation of UUSEC WAF error/access logs to prevent performance issues

**Security & Infrastructure**

- Expanded free SSL certificate support: HTTP-01 & DNS-01 verification across 50+ domain providers
- Customizable advanced WAF settings: HTTP2, GZIP, HTTP Caching, SSL protocols, etc
- Cluster configuration: Manage UUSEC WAF nodes and ML servers via web UI
