## Version History

<details>
  <summary>v1.6.0 - 30, April 2026</summary>

  **Velocity Tracking and Enhanced Response Structure**
  
  **Added**
  
  Trust Verification API:
  
  - Velocity tracking for multiple account detection from same IP
  - `has_multiple_emails_in_ip` response field indicating multiple accounts from same IP
  - `emails_in_ip` array in `analyzed_data` showing complete validation history per IP
  - Time-based velocity counters in `analyzed_data`:
    - `emails_in_ip_last_5_minutes` - Validations in last 5 minutes
    - `emails_in_ip_last_10_minutes` - Validations in last 10 minutes
    - `emails_in_ip_last_15_minutes` - Validations in last 15 minutes
    - `emails_in_ip_last_30_minutes` - Validations in last 30 minutes
    - `emails_in_ip_last_2_hour` - Validations in last 2 hours
    - `emails_in_ip_last_3_hour` - Validations in last 3 hours
    - `total_email_in_ip` - Total validations from IP across entire project
  - New validation step: `ip_duplication` for velocity tracking
  - New checked type: `multiple_emails_in_ip` for velocity checks
  - New risk breakdown signal: `high_velocity` for rapid account creation patterns
  
  Project Rules:
  
  - **Track Velocity** rule category
  - **Multiple Accounts from the Same IP Address** rule for detecting account creation abuse
  
  Documentation:
  
  - New **Checked Types** section documenting all validation type indicators
  - Complete velocity tracking example with response structure
  - Updated best practices for velocity monitoring
  
  **Changed**
  
  Trust Verification API:
  
  - `action` field now always returned
  - Removed specific "blocked" error codes:
    - `free_provider_domain_blocked`
    - `role_based_address_blocked`
    - `disposable_domain_blocked`
    - `known_abuse_domain_blocked`
    - `spam_trap_domain_blocked`
    - `not_educational_domain`
    - `not_government_domain`
  - Provider and classification rules now contribute to risk scoring and action determination instead of direct blocking
  
  Project Rules:
  
  - Renamed rule category: **Provider & Account Classification**
  - Rule behavior changed from blocking to checking:
    - **Free Provider Domain** (formerly "Block Free Provider Domains")
    - **Role-based Domain** (formerly "Block Role-based Addresses")
    - **Disposable Domain** (formerly "Block Disposable Domains")
    - **Known Abuse Domain** (formerly "Block Known Abuse Domains")
    - **Spam Trap Domain** (formerly "Block Spam Trap Domains")
    - **Educational Domain** (formerly "Educational Domains Only")
    - **Government Domain** (formerly "Government Domains Only")
  - Rules now perform checks that contribute to risk scores and actions
  - Only `not_in_specific_domains` error remains for specific domain restrictions
  
  **Improved**
  
  - More flexible validation logic based on risk assessment rather than hard blocking
  - Better fraud detection through velocity tracking across time windows
  - Enhanced account creation abuse detection
  - Automated bot attack identification
  - Bulk registration fraud prevention
  - Action-based responses provide clearer guidance on handling validations
  - Classification flags provide explicit detection results
  - Time-windowed velocity analysis for burst pattern detection
  
  **Use Cases**
  
  - Detect account creation abuse from same IP address
  - Identify automated bot registration attacks
  - Prevent fraudulent bulk account creation
  - Monitor velocity patterns across multiple time windows
  - Flag high-velocity signups for manual review
  - Track email validation history per IP address
  - Implement tiered verification based on velocity signals
