Mar 1, 2026March 2026 (Month: 2026-03) — Delivered concrete business value in release discipline, time accounting accuracy, and calendar/reporting capabilities for mikhailprivalov/l2. Key outcomes include: establishing release versioning milestones with v1 through v1.4 release tags to improve traceability and deployment planning; improving time tracking by excluding lunch from daytime hours and fixing date wrap when selecting a shift to ensure occupancy data reflects actual work time; enhancing reporting through XLSX export that now includes rate/occupied volume for capacity planning; expanding calendar/holidays capabilities with a holidays model, TypeScript typings, date utilities, and UI highlighting, plus incremental total time recalculation for accurate totals; and delivering several template/calendar enhancements (template column filling and template calendar days from a parent table) that improve data-driven scheduling. In addition, targeted lint fixes and cleanup reduced technical debt and improved build stability.
