* default config file moved to `src/` directory * documentation update: installation within virtual environment added
0.8.22
* uniform `ylim` in contour grouping and clustering plots * data underlying the grouping and plotting plots is stored in pickle files in the `opt.fsys.pic` subdirectory (see `copasul_plot.plot_grp()` and `copasul_plot.plot_clst()` for details)
0.8.21
* improved syllable extraction
0.8.20
* new energy gnl feature: `r_en_f0`, i.e. correlation between energy and f0 contour
0.8.19
* new parameter: `opt.styl.glob.align` for median window alignment center (default), left (no lookback), right (no lookahead) * new parameter subdict: `opt.preproc.interp` with element `.kind`. If set then `scipy.interpolate.interp1d()` is used with `kind` argument instead of default linear interpolation by `numpy.interp()`
0.8.18
* increasing robustness against vector length variation in `copasul_preproc.pp_zp()`
