Jul 1, 2025In July 2025, samply/blaze delivered a blend of testing enhancements, CI/CD improvements, and core architecture refinements that collectively increase reliability, performance, and business value. The FHIR query/testing surface was expanded with multi-code and multi-patient coverage, including resource-uniqueness checks in functional downloads and tooling to fetch patient IDs by identifiers, which strengthens test coverage and reduces risk in production data handling. CI/CD and build tooling were upgraded to improve validation fidelity—actionlint was integrated for GitHub Actions linting, Codecov path fixes were applied for accurate coverage reporting, and tooling versions were pinned to ensure reproducible builds. Core Blaze core evolved with asynchronous utilities modernization, a custom ByteString, versioned IDs, and refined database/test infrastructure to boost reliability and performance while enabling easier maintenance. Release readiness and observability were advanced through documented performance metrics and the release of v1.0.4, alongside improvements to test infrastructure. Major value came from stabilizing the development feedback loop: more comprehensive tests, faster and more deterministic CI, and a stronger foundation for future features and data-model evolution.

Apr 1, 2025April 2025: Key features delivered include system-version aware ValueSet validation with Terminology Operations UI; FHIR primitive Date/DateTime separation with value access on primitive types; and support for summary pull in search/system/history workflows. Major CI/CD and tooling improvements were implemented (build on push to main, Codecov default branch, clj-kondo upgrade). Integration tests were refactored for maintainability, and frontend/docs improvements enhanced developer experience. Critical reliability fixes addressed conditional delete in transactions, thread deadlocks on large batches, and Jackson string-length constraints; issues from PR #2557 were resolved. Release readiness for v0.34.0 and deployment notes were completed. These efforts improve data correctness, interoperability, performance, and business velocity by reducing risk and enabling faster delivery.
