• The daily interest rate functions (tr_yield_curve(), tr_bill_rate(), tr_long_term_rate(), tr_real_yield_curve(), and tr_real_long_term()) now attach an updated_at attribute to the returned table with the feed’s last update time.
• tr_yield_curve() now correctly labels the 1.5-month maturity added to the Treasury feed in February 2025 (previously shown as 1 _5month).
