April 2025 — hmcts/cnp-flux-config delivered two major features to strengthen reliability and control of S&F data delivery pipelines. The S&F Data Extraction Scheduling and Ad-hoc Resends feature enhances extraction scheduling for Smee and Ford data files and enables targeted resends via ADHOC_JOB_DATE across production config to meet specific delivery dates. The Probate S&F Cron Scheduling Standardization and Toggles feature standardizes cron timings, adds demo/config toggles, and supports testing windows to ensure reliable data delivery. Together, these changes improve operational reliability, reduce manual re-runs, and provide safer deployment controls for production data feeds.
