Oct 1, 2025

October 2025 – Performance and quality momentum for navikt/dp-behandling focused on building foundations for period-based vilkår, security and auditability, data correctness, and deployment discipline. Major work spanned PoCs for periodisering of vilkår and for Behandlingsresultat v2, security enhancements for meldekort handling, and improvements to logging, auditing, and test coverage. Several stabilization fixes and validation hardening lowered risk ahead of production rollout, while ongoing WIP efforts for reop with no fagsakId and resumption rule-sets set the stage for next milestones.

Aug 1, 2025

August 2025 — navikt/dp-behandling: Security, reliability, and business-value improvements with a strong push on access control, observability, and meldekort calculations, while stabilizing deployments and modernizing the build and packaging pipeline. Key features and fixes delivered include machine-token access control and vedtakstilgang, significant refactoring for idtyp naming, memory/CPU tuning to support higher load, and a Gradle 9.x upgrade with packaging modernization. Observability was enhanced through tracing and logging, with JMX-based debugging instrumentation and iterative tuning of resources. Meldekort calculations were clarified with additional verifications, improved rounding, and expanded scenario-based testing. Several stability and QA improvements were addressed, including loop avoidance, weekend workload fixes, test stability, and publishing cucumber reports. Also added support for rejecting cases due to disqualification and performed code cleanup (e.g., removing unused imports). These changes reduce deployment risk, improve security and compliance, and enable more accurate payouts and reporting.

Mar 1, 2025

March 2025 performance for navikt/dp-behandling focused on delivering high-value features, stabilizing core data flows, and strengthening deployment readiness. Key outcomes include a graph-based rule tree representation for dagpenger with GraphQL insert queries into GraphDB, enabling faster rule evaluation and easier regelverk population; Meldekort persistence and event handling with accompanying tests to ensure data integrity and reliable event processing; mapping of Aktivitetstype from RAMP data to internal representations to improve data consistency; ISO 8601 duration formatting using Kotlin Duration to improve interoperability; and a set of Meldekort lifecycle improvements including initial processing logic, queueing, and processing state tracking. Additional gains include namespace migration to nais for cloud alignment, startup initialization of business processes and information types, and deployment lifecycle tooling (Gradle 8.13) with dev deployments and rollback. Security logging for Meldekort and code-quality improvements (ktlint) further enhanced observability and maintainability.

Jan 1, 2025

January 2025 (2025-01) focused on stabilizing core deployment, expanding observability, and modernizing data models to accelerate delivery and improve reliability. Delivered a robust development deployment workflow with batch deployment support and rollback capability, enabling safer releases to the dev environment and smoother migrations via recreate/deploy strategies. Strengthened debugging and observability: added detailed logging for decision creation, and expanded rule execution traces to improve diagnosis and auditability. Improved rule reliability and stability through order-insensitive dependency comparisons and a temporary safeguard that re-evaluated the rule tree on clarifications (with a later rollback to restore long-term stability). Modernized data model and APIs with opplysningTypeId, UUID-based opplysningstype, and health-eligibility text; updated related SakRepository tests for better integration. Enhanced performance and safety: database indexing for opplysninger_opplysning, hourly deletion scheduling, and strengthened safety controls for deletions. Also delivered code quality improvements (ktlint fixes, cleanup, removal of deprecated constructors) to reduce technical debt and ease future maintenance.
