DEPENDENCIES

  - removed dependency on cctools.

NEW FEATURES

  - optimal plug-in bandwidth selection for all polynomial degrees
    (#38).

  - avoid randomness through simplified, deterministic jittering, see

  - headers in inst/include can be used as standalone C++ library with
    convenience wrappers for R (#41).

  - (several times) faster pkde1d(), qkde1d(), and rkde1d() due to a
    more clever algorithm for numerical integration (#42).

  - faster kde1d() thanks to the Fast Fourier Transform (#43).

BUG FIXES

NEW FEATURE

  - allow weights for observations via kde1d(..., weights = ) (#29).

BUG FIX

  - stabilized bandwidth selection in presence of ties and outliers.

  - keep debug symbols on Linux systems (following a request by Prof.
