Added
- covariance.GeodeticNoiseAnalyser: parametrize the residual noise allowing for non-Toeplitz/import
- plotting.geodetic/seismic added standardized residual histograms to residuals
- plotting.geodetic: new plot "geodetic_covariances"
- plotting.geodetic: add "individual" plot_projection to scene_fits to show stdz residuals
- plotting.seismic: fuzzy_bb, lune, hudson and fuzzy_mt_decomp support n_sources > 1
- plotting.seismic: allow plotting of fuzzy_bb for RectangularSource

Fixed
- plotting.marginals: stage_posteriors fixed axis unification and erroneous histogram plotting
- docs: short_installation fix python version to 3.8
- heart: pol_synthetics allow for RectangularSource
- covariance: estimation of variance on amplitude spectra instead of complex spectra

Contributors: Hannes Vasyura-Bathke hvasbath

Fixed
- FFI: do not init wavemaps during *SeismicComposite* init
- heart: flexible versioning for geodetic GF backend
- docs: correctly state python3.8 in installation instructions

Contributors: Hannes Vasyura-Bathke hvasbath

Added
- plotting.marginals.traceplot: source_idxs argument can be slice e.g. 1:10 to take mean of patch attributes
- heart.seis_derivative: function to numerically calculate derivatives wrt source attributes for waveforms
- heart.py, config.py: allow for version control for fomosto backends through "version" argument at *gf_config*
- utility: functions for slice to string conversion and vice versa
- config; NonlinearGFConfig added version attribute to specify backend version to use for GF calculation

Changed
- plotting.marginals.traceplot: CDF plotting of multiple distributions in a single subplot marks quantiles only once

Fixed
- plotting.marginals.traceplot: multipage output repeating variables

Contributors: Hannes Vasyura-Bathke hvasbath

Added
**FFI**
- add calculation of coupling to derived variables at *Fault* for the summarize method

**plotting**
- *plot_projection* argument available for *stage_posteriors* plot: cdf, pdf, kde
- update Example 8 to showcase the use of this functionality

Fixed
- stage_posterior plot supports multipage output, figsize fixed to fractions of A4
- multievent waveform_fits plot returns separate figures for each sub-event

Added
**Polarity**
- polarity module/composite/dataset-type for inference of wave onset polarities
- joint inference of P, Sh and Sv wave-polarities
- drawing of piercing points on fuzzyBB plot if polarity data exists
- drawing of fuzzyBBs for Sh and Sv waves
- add tutorial Example 8 for polarity inference

**Amplitude Spectra**
- added string-choice `domain` to WaveMaps to choose `time` or `frequency` domain for inference
- plotting: added spectra fits in waveform fits plot

**Continuous Integration (CI)**
- adapted installation scheme to fulfill PEP517 through pip and .toml
- providing beat binary packages on PyPi
- github actions workflow for code formatting and wheel building
- pre-commit and hooks for yaml, spellchecking, tailing whitespaces and eof

Changed
- split plotting module into plotting directory with submodules
- plotting: stage_posteriors change hist color to grey if only single density is shown
- plotting: fuzzyBB dashed white and black line instead of red for MAP
- docs: updated (short) installation instructions to use the package manager pip instead of setup.py

Added
**FFI**
- chain initialisation with lsq solution for seismic data
- resolution based discretization:
* add improved method of Atzori et al. 2019
* automatic damping estimation
* add Tutorial 4b to demonstrate the usage and functionality

**Plotting**
- 3d_slip_distribution: allows plotting of selected segments, slip-deficit, coupling, slip_variation
- gnss_fits: added Variance Reduction histograms if nensemble > 1
- slip_distribution: common colorscale and spatial scale across subfaults
- moment_rate: adjusted size and formatting to be publication ready
- correlation_hist: plot source related correlations for nsources > 1, colorcoding

Changed
- docs: rename former example 4 to example 4a

Fixed
- Bin backend: loading of traces with corrupt file header
- beat import: just import sampled variables
- RingFaultSource: allow sampling of slip-direction (sign)
