Changes in version 0.2.1 (2026-11-08)                  

  - CRAN resubmission. The placebo-inference example in ?ppsynth is
    \donttest{} rather than \dontrun{}. ppsynth_selftest() no longer
    calls set.seed(): its three toy designs are built from a fixed
    internal number sequence, so the function neither sets nor disturbs
    the user's random-number generator state.

                        Changes in version 0.2.0                        

  - Compiled inner solver (engine = "cpp", the default), mirroring the
    numba engine behind the Stata command; the pure-R solver stays
    available as engine = "r". Both are certified against the Python
    engines (see inst/certification).
  - cores argument: the leave-one-out folds and the placebo units run in
    parallel; results do not depend on cores.
  - Package renamed from ppsynthR to ppsynth.
  - Germany placebo-inference fixture added to the certification set.

                        Changes in version 0.1.0                        

  - First release: pure-R port of ppsynth_core.py (PPSYNTH v2.6.1), the
    Stata command's option set, display and graphs, certified against
    the Python engine on the Germany panel, the shipped test panel and
    the three self-test designs.
