Changes for QuantLib 1.40

Removals and deprecations

Features deprecated in release 1.35 were removed in this release; see
#2268 for a full list.

A number of features were deprecated in this release and will be
removed in a future release:

• The overload of the RangeAccrualFloatersCoupon constructor taking a shared_ptr to a schedule; use the other overload instead.
• The method observationsSchedule of the same class; use observationSchedule instead.
• The <ql/experimental/fx/blackdeltacalculator.hpp> and ql/experimental/fx/deltavolquote.hpp headers; use <ql/pricingengines/blackdeltacalculator.hpp> and <ql/quotes/deltavolquote.hpp> instead.
• The overload of the CPIBond and CPIBondHelper constructors taking the growthOnly parameter; use the other overload instead.
• The methods cumD1, cumD2, nD1 and nD2 of the BlackDeltaCalculator class; they are internal methods and will be moved to the private section.
• The BlackDeltaPremiumAdjustedSolverClass and BlackDeltaPremiumAdjustedMaxStrikeClass; they were used in the implementation of BlackDeltaCalculator but are now obsolete.
• The BootstrapError class template; use a lambda instead (see #2263 for an example).
• The PenaltyFunction class; use SimpleCostFunction instead.
• The Tona index was renamed to Tonar; use the latter instead.
