20 Commits • 10 Features
Apr 1, 2026April 2026 delivered substantial EvitaDB enhancements spanning query capabilities, analytics, and release discipline, driving business value through richer data queries and safer, faster releases. Key features include Evita Expression Language method invocation support with ObjectMethodAccessor dot-notation and usage documentation; EvitaQL added new primary-key comparison operators in the interpreter grammar; ReferenceSummary API enhancements introduce extra results and backward compatibility with FacetSummary, backed by GraphQL/REST tests. In analytics, histogram statistics in extra results were expanded to support dynamic reference histograms, while removing attributeHistograms and updating tests and index retrieval for maintainability. For stability and quality, fixes include ObjectAccessOperator merge conflict resolution and adjustments to EvitaDB query expression visitor data paths for nested constants. The team also advanced risk mitigation and developer tooling with AI-assisted schema breaking-change analysis, automated GraphQL/OpenAPI compatibility checks, EvitaLab upgrade to v2026.2.0, and documentation improvements for external API objects and bug-hunting/TDD tooling. Overall impact: broader query expressiveness, richer analytics outputs, reduced release risk, and faster onboarding for clients integrating GraphQL/REST/gRPC APIs.

Oct 1, 2025October 2025 delivered key platform improvements in evitaDB: API mutation handling refactor, CDC streaming enhancements across REST/GraphQL, language grammar upgrades in EvitaLab, and code style standardization. The API mutation refactor introduces new mutation descriptors, renamed classes, and an aligned mutation schema, enabling clearer, more extensible mutations. CDC API and streaming provide REST/GraphQL endpoints, DTOs, WebSocket handlers, and live streaming of system and catalog changes, with accompanying documentation. EvitaLab grammar upgraded to 2025.6.0 to improve syntax support and editor tooling. A targeted code style cleanup standardized chained call alignment with no functional changes. Overall, these efforts improve API clarity, enable real-time data propagation, and enhance developer productivity and maintainability, aligning with roadmap goals.
