Sep 1, 2025September 2025 delivered a focused set of reliability, UX, and maintainability improvements for lsfusion/platform. Key features added include UI caption humanization with default uncamel-cased captions, dynamic field inclusion for EXPORT/JSON forms via SHOWIF and EXTNULL, file handling improvements across FTP/SFTP with backward compatibility, and a structural AI package refactor under lsfusion.ai. Major bugs fixed include correct triggering of object reading in Input List Order By Rank, consolidated remote invocation reliability across desktop and web clients, a safer DataGrid null-check path, and fixes to EXPORT/JSON property export and LOCAL handling. A new centralized database executeAction path tightened error management. Together these changes improve cross-client reliability, user experience, data export correctness, and code maintainability.

Key features delivered: - Language parsing and explicit parameter handling improvements: refactored BaseUtils (removeList, toList) and enhanced LsfLogics.g grammar to support explicit parameter classes and context-dependent logic, including fixes to property definitions accessed via [] operator. Major bugs fixed: - Data processing reliability fixes for large datasets: corrected asynchronous statistics calculation by adjusting joins and stabilized JSON FROM type handling to ensure correct results. - Performance and correctness improvement for objectClass handling: improved objectClass equality checks by using static expressions for faster, more reliable comparisons. Internal stability and maintainability improvements: - Align internal DB actions with the current SQL connection, improve error handling and stack traces, refine integral type step calculations, and rename system properties for clarity; added logs for recursion detection. New capabilities and business impact: - Input sorting: introduced inputListOrderByRank setting to control sorting of input lists, with InputPropertyValueList updated to support the new behavior, enabling more deterministic processing pipelines. Technologies/skills demonstrated: - Refactoring and parser grammar enhancement, improved error reporting, concurrency/async handling, JSON type management, and configuration-driven feature development.
