March 2026 highlights: Delivered substantial API hardening, stability, and performance improvements across Camunda's core platform. Key work spanned API schema enforcement, test infrastructure hardening, in-memory data processing optimizations, and time-handling enhancements, delivering stronger data integrity, faster feedback loops, and more predictable behavior in production and CI. Key features delivered and bugs fixed: - API and core-domain data integrity hardening: enforced required and non-nullable fields across major models (EvaluateDecisionResult, DecisionDefinitionResult, DecisionRequirementsResult, CamundaUserResult, BatchOperationResult) and core surfaces (Document API, process statistics, process instances, incidents stats, jobs, variables), reducing data inconsistencies and API surface risks. - Deployment/Cluster/Conditional API schema enforcement: declared required response fields for Deployment, Cluster, and Conditional APIs, improving API reliability and downstream client integration. - Test reliability and environment hardening: fixed test listener cleanup to avoid side effects; disabled long polling in the test container to prevent stale job claims and flakiness in CI. - Performance and data handling enhancements: implemented key-only iteration (forEachKey, whileTrue, whileEqualPrefix, whileTrueReverse) for InMemoryDbColumnFamily to speed up DB operations; improved authorization sorting with a default sort field and a unique discriminator to enable correct keyset pagination; introduced time handling improvements (OffsetDateTime for audit logs and overloads for date-time fields) to improve correctness and UX. - Dependency stability and documentation improvements: downgraded Zeebe to 8.9.0-SNAPSHOT to avoid breaking changes and updated docs to reflect clarifications on module compatibility and hasMoreTotalItems descriptions.
