Sep 1, 2025September 2025 monthly summary for siemens/element: Delivered performance and reliability enhancements across key Formly components and the File Uploader. Key changes include adopting OnPush change detection by default for wrappers and structural components (affecting SiFormlyFieldsetComponent, SiFormlyHorizontalWrapperComponent, SiFormlyIconWrapperComponent, Accordion, Array, Object Grid, Object Plain, Object, and Tabset) with commits 87c06d517a21bdfa6f47c434878db6d59ec98d40 and 680ea8aeef8592dd53185ac2e97ce8174af8422b. Also fixed file uploader to allow concurrent uploads in auto-upload mode, triggering uploads on changes without manual intervention (commit fb9787305f5d1fd913959cfed4fe02a35c356c24). Overall impact: reduced change-detection cycles, faster rendering, improved auto-upload reliability, and clearer maintenance path. Technologies/skills demonstrated: Angular OnPush strategy, Formly integration, performance optimization, concurrency handling in file uploads, and codebase hygiene.
