Release 1.2.1: * Fix bug in sfstnormalize --method=kl_min_approximated using kl_min * Deprecate the `CountNormType`'s `NORM_MARGINALLY_CONSTRAINED` and `NORM_MARGINALLY_APPROXIMATED` in favor of `NORM_KL_MIN` and `NORM_KL_MIN_APPROXIMATED` respectively. Release 1.2: * Improved speed of approximations * Added entropy semiring * Changed Perplexity to accept for general sources ('p') and targets ('q') Release 1.1: * Changed Approx and NGramApprox to compute the KL minimum solution (via improved CountNormalize); now the default * Added Intersect() * Added sfstcount, sfstintersect, sfstshortestdistance, sfsttopology Release 1.0: * Initial public release
