- /stats/economy defaults multi-country charts to CAN KOR CHN JPN USA NLD CUW, with add-a-country chips and an EU 27 comparison line - CPI index levels rebased to a chosen base year, index/YoY toggle, categories (food, energy, housing, core) where the source has them - new no-key collectors: oecd (CPI categories, 10y yields), statcan (CPI); bis WS_LONG_CPI, FRED US CPI categories, Eurostat prc_hicp_minr, WB FP.CPI.TOTL - Canada added as a region; CBS Curacao fallbacks for growth/unemployment - timers stats-oecd and stats-statcan
