This release marks the second minor update to version 4 of the Findwise i3 platform. 

With the release of version 4.2.0 we bring several important improvements across services and infrastructure. The release also addresses bugs and issues present in previous versions. Additionally, security enhancements have been introduced to help safeguard the Findwise i3 platform against potential threats.

For more detailed information, please refer to the changelog below.

Improvements

• Spring Boot upgrade to the latest version 3.4.7
• Index service performance improvements:
  • Optimization to fetching collections' summary
  • Optimization to log truncation execution
• Modularization of AI-Models:
  •  i3- AI-Models have been split into separate Docker images for improved modularity and maintainability
  • No longer supported TorchServe has been replaced with the supported FastAPI
• Kubernetes deployment support:
  • Default configuration for i3 deployment with k8s, including Helm charts, has been created to simplify setup and onboarding
• New feature in Search:
  •  Reciprocal Rank Fusion (RRF) introduced as a new search feature to improve result relevance and ranking
• New Elastiscsearch features:
  • API Token Authentication as an additional authentication method for Elasticsearch, enhancing security and integration flexibility
  • Synonyms API to manage and test synonym rules dynamically
  • Native ES8 vector search compatibility instead of Elastiknn plugin for better performance and compatibility

Bug fixes

• [FP-1338] Fix bug in document removing in Connect
• [FP-1478] Quering documents by date translates to wrong date
• [FP-1544] Documents with reserved characters are not removing via Index GUI
• [FP-1550] Truncation on document view in colleciton view throws exception
• [FP-1277] Fix NER stage that does not create child nodes
• [FP-1529] Fix broken CSS for synonyms
• [FP-1536] Fix deprecated Solr configuration

Removals

• N/A

Versions of key components

• Java 17
• Elasticsearch 8.15.5
• Keycloak 26.0.3 (client), 26.0.7 (reference image)
• Lucene 9.11.1
• Apache Solr 9.8.0 (client & reference image)
• MongoDB 7.0.16 (reference image)
• Docker base image 17.0.13_11-jre-jammy

Breaking Changes

• As the result of FP-1602 we divided i3-ai-models into separate docker images. Each ai-model is currently built into separate Docker image and runs as a separate Docker container. This helps address issues with conflicting dependencies between models and fixing vulnerabilities when updating dependencies. Additionally, the no longer supported TorchServe has been replaced with the supported FastAPI. This change redefines the method for customizing existing models and modifies the associated Docker Compose configurations.
