Release v3.2.0 into Main

[github-actions]

Key Features

Enhanced Deployment Configuration

• 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

Important Note

• 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

Admin UI Configuration Page

• 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

LISA Documentation Site

• 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

Enhancements

• 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

Bug Fixes

• 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

Coming Soon

• 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.
