### Enhancements

[#enhancements](docId\:qOe9Nqgw2qVdbTQXX2F0e)

- **Batch Processing for User Profile Service (UPS)**: Added support for batch processing in `decideAll` and `decideForKeys`, enabling more efficient handling of multiple decisions in the User Profile Service. ([#394](https://github.com/optimizely/go-sdk/pull/394))
- **Optimized Logging**: Reduced log verbosity in the Decision flow by shifting info-level logs to debug. This change will significantly reduce the volume of logs at the info level, improving readability and performance for applications with high decision-making activity. ([#390](https://github.com/optimizely/go-sdk/pull/390))
