Oct 1, 2025October 2025 Monthly Summary for SciCatProject/scicat-backend-next: Focused on delivering resilient data workflows and enhanced observability. Highlights include two major feature areas that improve pipeline reliability and data completeness: (1) Dataset information propagation across actions and (2) Unified ignoreErrors support for URL and Email actions. These changes reduce action failures due to missing datasets, allow critical pipelines to continue in the face of non-fatal errors, and improve visibility for faster triage.

May 1, 2025May 2025 monthly summary for SciCatBackendNext: Key features delivered include a Unified Template Context and Env-based Configuration for Job Actions, enabling standardised Handlebars variable access, secure environment-based secrets via {{env}}, dataset caching in job context, and URL action header templating via environment variables. Also introduced Customizable Default Status for New Jobs with environment-driven defaults (JOB_DEFAULT_STATUS_CODE and JOB_DEFAULT_STATUS_MESSAGE), and an Enhanced Switch Action with Phase Control and Robust Property Referencing, including improved dataset property access and updated tests. Commit activity highlights targeted feature work and tests across three features, plus a specific fix/refactor to support phase control. Overall, this work improves reliability, security, and consistency across job actions, reduces configuration overhead, and strengthens job orchestration and observability.

Apr 1, 2025April 2025 monthly summary for SciCatProject/scicat-backend-next. Delivered feature enhancements across job orchestration and dataset management, reinforced security, and improved developer experience through documentation. Key outcomes include cross-dataset property matching in SwitchJobAction, extension of dataset lifecycle schema with storageLocation, and comprehensive job configuration documentation. Security posture was enhanced by removing logging of the MongoDB connection URI. The changes collectively improve robustness, data governance, and onboarding, while enabling more flexible multi-dataset workflows and clearer configuration among teams.

Jan 1, 2025January 2025 monthly summary for SciCatProject/scicat-backend-next: Delivered Microsoft Graph email transport support enabling email delivery via Microsoft 365 in addition to SMTP. The email subsystem now dynamically selects transport type at runtime, with a new MSGraphMailTransport class handling Graph API communication. Environment variables were updated to configure the Graph transport while preserving SMTP compatibility. This work expands cloud-friendly, enterprise-grade email delivery and reduces dependency on SMTP while aligning with modern Microsoft 365 integrations.
