      (see #2045)
    * Fixed the check for new PSD slices whether they should be added or whether
      they would add unwanted duplicated data (see #2229)
+   * Fix `period_lim` option when `xaxis_frequency=True` (see #2246)
  - obspy.signal.cross_correlation:
    * Add new `correlate_template()` function with 'full' normalization option,
      required for correlations in template-matching
