| 2 | +## Key Features |
| 3 | +### Enhanced Deployment Configuration |
| 4 | +- LISA v3.2.0 introduces a significant update to the configuration file schema, optimizing the deployment process |
| 5 | +- The previous single config.yaml file has been replaced with a more flexible two-file system: config-base.yaml and config-custom.yaml |
| 6 | +- config-base.yaml now contains default properties, which can be selectively overridden using config-custom.yaml, allowing for greater customization while maintaining a standardized base configuration |
| 7 | +- The number of required properties in the config-custom.yaml file has been reduced to 8 items, simplifying the configuration process |
| 8 | +- This update enhances the overall flexibility and maintainability of LISA configurations, providing a more robust foundation for future developments and easier customization for end-users |
| 9 | + |
| 10 | +#### Important Note |
| 11 | +- The previous config.yaml file format is no longer compatible with this update |
| 12 | +- To facilitate migration, we have developed a utility. Users can execute `npm run migrate-properties` to automatically convert their existing config.yaml file to the new config-custom.yaml format |
| 13 | + |
| 14 | +### Admin UI Configuration Page |
| 15 | +- Administrative Control of Chat Components: |
| 16 | + - Administrators now have granular control over the activation and deactivation of chat components for all users through the Configuration Page |

| 31 | +### LISA Documentation Site |
| 32 | +- We are pleased to announce the launch of the official [LISA Documentation site](https://awslabs.github.io/LISA/) |
| 33 | +- This comprehensive resource provides customers with additional guides and extensive information on LISA |
| 34 | +- The documentation is also optionally deployable within your environment during LISA deployment |
| 35 | +- The team is continuously working to add and expand content available on this site |
| 36 | + |
| 37 | +## Enhancements |
| 38 | +- Implemented a selection-based interface for instance input, replacing free text entry |

| 41 | +- Introduced options for administrators to choose between Private or Regional API Gateway endpoints |
| 42 | +- Enabled subnet specification within the designated VPC for deployed resources |
| 43 | +- Implemented support for headless deployment execution |
| 44 | + |
| 45 | +## Bug Fixes |
