April 2026 highlights: Achieved cross-repo modernization by upgrading core stacks to Spring Boot 3.5.11 and aligning dependencies across gridsuite/deployment, gridsuite/filter-server, gridsuite/explore-server, gridsuite/directory-server, and gridsuite/dynamic-simulation-server; updated deployment dependencies for Elasticsearch and Minio; released computation module 2.1.0; and shifted testing approach by removing Testcontainers. These changes deliver improved security posture, performance, and maintainability, enabling smoother future releases across the gridsuite suite.

February 2026: Delivered cross-repo voltage configuration enhancements, code cleanup, data integrity improvements, UX refinements, and enhanced observability. Key items include: adding base-voltages-config to sld-application.yml in gridsuite/deployment and migrating to a conf-based voltageconfig in powsybl-single-line-diagram-server; removing legacy baseVoltagesConfig across gridsuite/gridstudy-app; introducing a computeQ0 utility for StaticVarCompensator creation; and improving UI consistency with pagination resets on global filter changes and robust parsing of user-added property columns. Observability was boosted by enhanced logging for unexpected request parameter values. These changes reduce maintenance overhead, improve calculation reliability, and deliver a smoother data-view experience for users across the SLD ecosystem.

Concise monthly summary for 2026-01 highlighting features delivered, bugs fixed, impact, and technologies demonstrated across gridsuite/gridstudy-app and gridsuite/study-server.

December 2025 monthly summary: Focused on stabilizing the platform while delivering business value through strategic releases, dependency management, and reliability improvements across PowSyBl and GridSuite services. The team delivered key client releases, stabilized core stacks, and enhanced error handling and configuration capabilities to improve operator efficiency and system resilience.

November 2025 Monthly Summary: Delivered stability, observability, and documentation improvements across powsybl and gridsuite repositories while migrating to Spring Boot 3.4.9. Key stability win: RestTemplate configuration avoided hangs during SB 3.4.9 upgrade; major reliability uplift in NetworkConversionService with managed RestTemplate; API documentation enhanced with Swagger 2.2.36; widespread adoption of Spring Boot managed RestTemplate enabled automatic traceId propagation, significantly improving distributed tracing and debugging. Result: reduced upgrade risk, better system observability, and clearer API surfaces across 14 repositories. Technologies and skills demonstrated: Spring Boot 3.4.9, RestTemplate and SimpleClientHttpRequestFactory, Spring Boot managed RestTemplate, distributed tracing with traceId, Swagger documentation.

October 2025: Concise monthly summary focusing on bug fix and versioning governance. Key accomplishments include a critical test reliability improvement via a TCK visibility fix, and consolidated versioning/dependency maintenance across powsybl-ws-commons, including a Spring Boot upgrade and release instrumentation. The work enhances test stability, release cadence, and codebase governance.
