Release v3.2.0 · awslabs/LISA

Key Features

LISA v3.2.0 introduces a significant update to the configuration file schema, optimizing the deployment process
The previous single config.yaml file has been replaced with a more flexible two-file system: config-base.yaml and config-custom.yaml
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
The number of required properties in the config-custom.yaml file has been reduced to 8 items, simplifying the configuration process
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

The previous config.yaml file format is no longer compatible with this update
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

Administrative Control of Chat Components:
- Administrators now have granular control over the activation and deactivation of chat components for all users through the Configuration Page
- This feature allows for dynamic management of user interface elements, enhancing system flexibility and user experience customization
- Items that can be configured include:
  - The option to delete session history
  - Visibility of message metadata
  - Configuration of chat Kwargs
  - Customization of prompt templates
  - Adjust chat history buffer settings
  - Modify the number of RAG documents to be included in the retrieval process (TopK)
  - Ability to upload RAG documents
  - Ability to upload in-context documents
System Banner Management:
- The Configuration Page now includes functionality for administrators to manage the system banner
- Administrators can activate, deactivate, and update the content of the system banner

We are pleased to announce the launch of the official LISA Documentation site
This comprehensive resource provides customers with additional guides and extensive information on LISA
The documentation is also optionally deployable within your environment during LISA deployment
The team is continuously working to add and expand content available on this site

Implemented a selection-based interface for instance input, replacing free text entry
Improved CDK Nag integration across stacks
Added functionality for administrators to specify block volume size for models, enabling successful deployment of larger models
Introduced options for administrators to choose between Private or Regional API Gateway endpoints
Enabled subnet specification within the designated VPC for deployed resources
Implemented support for headless deployment execution

Resolved issues with Create and Update model alerts to ensure proper display in the modal
Enhanced error handling for model creation/update processes to cover all potential scenarios

Version 3.3.0 will include a new RAG ingestion pipeline. This will allow users to configure an S3 bucket and an ingestion trigger. When triggered, these documents will be pre-processed and loaded into the selected vector store.
