 Changes currently on master, but not under a tag.
 
 ### Added
-- Clean up of `detectors.py`: adds an `InterferometerStrainData` to handle strain data and `InterferometerSet` to handle multiple interferometers. All data setting should primarily be done through the `Interferometer.set_strain_data..` methods.
+- InterferometerStrainData now handles both time-domain and frequencu-domain data
 - Adds documentation on setting data (https://monash.docs.ligo.org/tupak/transient-gw-data.html)
 - Checkpointing for `dynesty`: the sampling will be checkpointed every 10 minutes (approximately) and can be resumed.
 - Add functionality to plot multiple results in a corner plot, see `tupak.core.result.plot_multiple()`.
 - Likelihood evaluations are now saved along with the posteriors.
 
+### Changed
+- Clean up of real data handling: all data is now windowed with a 0.4s roll off (unless set otherwise) and low-pass filtered.
+- Add explicit method to create a power spectral density from time-domain data
+- Clean up of `PowerSpectralDensity()` - addds `set_from` methods to handle various ways to define the PSD.
+- Clean up of `detectors.py`: adds an `InterferometerStrainData` to handle strain data and `InterferometerSet` to handle multiple interferometers. All data setting should primarily be done through the `Interferometer.set_strain_data..` methods.
+- Fix the comments and units of `nfft` and `infft` and general improvement to documentation of data.
+- Fixed a bug in create_time_series
