Minor Release Notes (v8.1.0)
----------------------------


### Added
- Compatibility of whole code base with Matlab compiler in order to run `spm_make_standalone`
    - provides oppurtunity to run SPM Batch Editor GUI version of PhysIO without Matlab license requirement 
    - compiled version readily available within [Neurodesk](https://neurodesk.github.io/tutorials/fu...
- BIDS Read-in for separate cardiac/respiratory trace files (e.g., due to different sampling frequencies)
    - see GitHub Issue #164 and pull request #167 by @alexsayal
    - Additional unit tests for new read-in and example data


### Changed
- Switch for certain toolbox functions (e.g., `imtool`) to only run in 
  non-compiled code


### Fixed
- Documentation (function headers, see Github issue #149)
- Typos in unused function (spotted in compilation)
- Synchronization SIEMENS AcquisitionLog / Physiological files (see Github issue #172)
    - better visualization of sync, clearer error messages if dummy scans not found


Bugfix Release Notes (v8.0.1)
-----------------------------


### Changed
- Citation of novel [TAPAS paper](https://doi.org/10.3389/fpsyt.2021.68081...) in README and CITATION



Major Release Notes (v8.0.0)
----------------------------


### Added
- New method for computing respiratory volume per unit time (RVT) via the
  Hilbert transform.
    - Publication: Harrison et al., "A Hilbert-based method for processing
      respiratory timeseries", NeuroImage, 2021.
      <https://doi.org/10.1016/j.neuroimage.2021.117787>
    - This is now the default option, but the old method is available by
      setting `physio.model.rvt.method = ''peaks''` (or the equivalent within
      the SPM batch editor).


- Respiratory preprocessing now includes an optional de-spiking step based on
  median filtering.


### Changed
- Now possible to change the frequencies of the respiratory filtering during
  preprocessing via `physio.preproc.respiratory.filter` (or the equivalent
  within the SPM batch editor).


- More robust detrending of raw respiratory timeseries via windowed padding
  before filtering.
