June 2025 performance summary for the Limited Partnerships program. Delivered key frontend and API improvements that enhance onboarding, payment reliability, data integrity, and developer experience. Frontend work introduced a dedicated Payment Failure screen with status-based routing, updated Back link behavior, and regression tests, improving user clarity during failed payments. Onboarding UX and localization were strengthened with improved date handling for partner DOBs, corrected type handling, and added translations across GP/LP screens (including Welsh). Navigation UX was refined with dynamic Back link navigation and page-specific routing fixes for General and Limited Partners. Partner registration was simplified by removing the legal_personality_statement_checked field, reducing form complexity. API and platform resilience was improved through validation enhancements, filing integrity checks, restricted costs endpoints, interceptor refinements, and broader test coverage and code quality improvements. These changes reduce risk in filings, improve data quality, and enable smoother onboarding and easier maintenance.
