v0.1.0

0.1.0 (2026-10-24)

Added

• mtwnEaseCubicBezier samples a cubic-bezier easing with the same
  bits as mtwnEase. With link-time optimization or unused sections
  dropped, a program that samples cubic beziers only through it links
  none of the other curves.

Changed

• An underdamped spring whose phase (damped rate times time) is at
  least 2^52 radians while its envelope is not yet 0 now takes its sine
  from the exact argument reduction. There, mtwnSpringMotionAt,
  mtwnSampleSpring and the spring easings, bounded decays and spring
  transitions built on them return different bits; results below 2^52
  are unchanged.
• Grouped players cost less: with groups, an update of 1,000 players in
  step takes 1.6% more instructions than without them, down from 14.4%.

Fixed

• A critical or overdamped spring whose start overflows its settling
  bound (stiffness times offset past about 1.8e308) gave a NaN settling
  time. mtwnSpringSettlingTime and mtwnBoundedDecayStopTime now
  return infinity, as the capped path already did. A spring transition
  from such a start, which ended at once (a path jumped to its target,
  other kinds ended with the other channels), now never ends by
  settling. Where only the offset bound overflowed, the settling time
  was the velocity bound's early finite time; it is now infinity too.
