February 2025 (Kong/spec-renderer): Focused on stabilizing rendering for large specifications. Key fix: introduced a computed doContentScrolling to determine whether content scrolling should be disabled, based on the allowContentScrolling prop and the number of children in the spec document. This change addresses a bug where content scrolling remained enabled for large specs, delivering measurable improvements in performance, UX, and stability when rendering dense specs. The work is tracked under commit b3bdf1905ca32568650df059cd1177556d04272b (fix: force disable content scrolling for large specs [KHCP-15276]).
