+- **Suspicious Password Change Detection**: Automatically monitors and logs instances where a password is changed shortly after logging in, helping to identify potential account hijacking.
+- **Geo-Velocity Tracking**: Implements a check for the physical feasibility of user movement between consecutive logins based on login locations and timestamps.
+- **VPN and Proxy Detection**: Integrates with the IP2Location service to identify logins from VPNs and proxies, flagging potentially masked IP addresses and location spoofing.
+- **Session-Specific Event Logging**: Each login session is now uniquely identified and tracked, allowing for more precise security monitoring and reducing the likelihood of false positives in security event detection.
+- **Customizable Configuration**: Allows users to set their IP2Location API keys and configure other settings for tailored security measures.
+- **Rails Session Integration**: Utilizes Rails session mechanism to track and associate user activities with specific login sessions.
+- **Improved Documentation**: Expanded README and in-code documentation for easier setup and usage.
 
 ### Changed
-- Discussion and clarification on the `after_update` callback behavior, particularly related to `changed?` and `saved_change_to_attribute?` methods.
+
+- **Refactored Event Logging**: Transitioned to a model where each login event is stored as a separate record for more accurate tracking.
+- **Enhanced Security Checks**: Updated methods for more precise detection of suspicious activities, including the use of latitude and longitude for geo-velocity calculations.
