v5.31.3

Fixed

• viewer.financial_statements returned wrong income statement for filings with multi-row period headers (e.g. ADI 2019 10-K mislabeled annual columns as quarterly). The R*.htm header parser was rewritten to walk <thead> row by row and filter footnote markers. Affected most 10-K/10-Q filings silently. (#812, reporter @mpreiss9)

• Financials.get_net_income() returned wrong value (often wrong sign) for filers reporting a net loss with a separate noncontrolling-interest line — for Micron Q2 2013 returned +$2M (the NCI row) instead of -$286M. Also fixes IFRS 20-F filers whose row label isn't "Net income" (e.g. Barclays "Profit after tax"). Concept lookup is now exact and IFRS-aware. (#814, reporter @wei-jianlin)
