Version history

Release 0.3.8 - December 2004

REQUIRED PACKAGES

  • Boost version 1.31.0 or later is now required.

DOCUMENTATION

  • Documentation now includes a FAQ page.

GLOBAL FEATURES

  • Global evaluation date added through Settings class. Used for index-fixing and exchange-rate lookup.
  • added InterestRate class, which encapsulate the interest rate compounding algebra. It manages day-counting convention, compounding convention, conversion between different conventions, and discount/compounding factor calculations. It also has its own formatter.

INSTRUMENTS

  • Bond and FixedCouponBond classes added (thanks to Jeff Yu) providing price/yield conversions; tests provided.

DATE, CALENDARS, AND DAY COUNT CONVENTIONS

  • Reworked Date interface. Added nextWeekday() and nthWeekday() static methods to the class Date. Added nextIMM() for the calculation of the next IMM date.
  • Added WeekdayFormatter and FrequencyFormatter
  • Added "1/1" day counter. The Actual365 is deprecated: as per ISDA documentation "Actual/365" is the same as "Actual/Actual". Use the ActualActual class instead, or the Actual365Fixed class.
  • Added dayCounterFromString(std::string) to QuantLibFunctions.
  • Improved Beijing calendar (thanks to Zhou Wu.)

CURRENCIES AND FX RATES

  • Added currency classes; CurrencyTag replaced in library code.
  • Added money class providing arithmetic with or without conversions; tests provided.
  • Added exchange-rate class; tests provided.
  • Added exchange-rate manager with smart rate lookup, i.e., able to derive a missing exchange rate as a chain of provided rates; tests provided.

MONTE CARLO FRAMEWORK

  • Added Faure low-discrepancy sequence (thanks to Gianni Piolanti;) tests provided.
  • Added randomized (shifted) low discrepancy sequences that will be used for randomized quasi Monte Carlo.
  • Added SeedGenerator class, for random generation of seeds when they are not given by the user.
  • Added the implementation of Sobol sequences using the coefficients of the free direction integers as provided by Bratley and Fox, who credited unpublished work of Sobol's and Levitan's.
  • Added an implementation of Sobol sequences using the coefficients of the free direction integers of Lemieux, Cieslak, and Luttmer. Coefficients for d<=40 are the same as in Bradley-Fox. For dimension 40<d<=360 the coefficients have been calculated as optimal values based on the "resolution" criterion. The values has been provided by Christiane Lemieux, private communication, September 2004.
  • PathGenerator now works correctly with processes describing S instead of log S. Geometric Brownian process added (thanks to Walter Penschke.)

LATTICE FRAMEWORK

  • Reworked the DiscretizedAsset interface.

  • Added compilation flag to select default floating-coupon type.
  • IndexedCoupon can now take a generic index rather than a Libor (thanks to Daniele De Francesco.)
  • Added hooks for convexity adjustment in floating-rate coupons; implemented adjustment for InArrearIndexedCoupon.
