2.0.0

Notable changes

• Unix time input is now supported as unsigned long.
• Optimizations for code size and performance:
  • Neglect of all terms < 0.005 degree, including higher powers of time T (in Julian centuries), nutation, and ΔT.
  • Simplified expressions for the Julian day, atmospheric refraction correction, equation of time, and ΔT.
  • Simplified rising, transit, and setting algorithm.
• New iterations parameter in calcSunriseSunset, which can be set to 0 to get the approximate times.
• New example sketch for the rise and set times at a height above the horizon (using the altitude parameter).

Breaking changes

• Sun's radius vector is now calculated with calcEquatorialCoordinates.
• Some intermediate calculations have been removed, e.g. nutation.
