December 2025 monthly summary: Delivered substantial enhancements to release-date calculations for FTR56, improved validation messaging and error handling, and extended date logic to support new sentence types and concurrent sentences. Implemented FTR_56ORA and added a Calculation Summary tranche notification, with backend/frontend alignment and targeted refactors (BookingExtractionService) and tests. Tech stack primarily Kotlin/Java backend with front-end UI updates for user alerts. These changes increase reliability, reduce regulatory risk, and provide clearer, earlier visibility into tranche-driven changes for policy compliance and operations.

September 2025 monthly summary for the release-dates domain. Delivered key features and fixes across ministryofjustice/calculate-release-dates and ministryofjustice/calculate-release-dates-api, focusing on business value: improved release date accuracy, reduced manual effort, and strengthened validation and policy compliance. Major work combined enhancements to the manual entry flow, API-level deduplication, repeal-rule handling via feature toggles, and clearer NOMIS error messaging. This cycle also included targeted fixes to ensure calculations can proceed when users select 'None of the above' and safeguards for re-approval of previous calculations. Impact highlights include a streamlined user journey for caseworkers, reduced risk of duplicate calculations, and faster, more reliable release-date decisions aligned with policy changes. The work was accompanied by improved integration tests and environment configuration updates to support feature flags and validation messaging. Key technical outcomes include: improved session-based storage for manual entry, backlinks between date input steps, redirect safeguards, API-level checks to skip unnecessary manual calculations, a feature-toggle for post-recall repeal rules, and explicit NOMIS line references in validation messages.
