## [Unreleased]

empty

## [2021.06.29]

Added

  • Windows support (experimental).
  • Jackseis: can now use 3-digit Julian day in output filename templates.

Changed

  • Snuffler: improved fidelity when working with many markers. It should now be possible to smoothly handle 100.000 markers. The option --disable-marker-sorting can be supplied to disable sorting in the marker side-panel for an additional speedup.
  • Improved high precision (HP) time handling. Pyrocko now has two distinct modes for time handling. Timestamps are now handled either as 64-bit floats or as 96/128-bit floats. The mode can be selected by environment variable, config setting or by a call to util.use_high_precicion_time at program startup. HP time mode is only available on platforms where NumPy's HP floats are available. HP time mode is necessary when handling data with sampling rates above 100 kHz.
  • Dropping support for Python 2 binary distribution packages (Anaconda and PIP).
  • Python 2 support will be removed from Pyrocko in the near future in order to reduce our maintenance and testing workload. Sorry.

Fixed

  • Fixed an error in Double-DC source which caused incorrect placement of the sub-sources.

## [2021.04.02]

### Added

  • RectangularSource: added opening_fraction to model tensile dislocations
  • New command line option for jackseis: --record-length
  • Timing definition offsets can now take % as suffix to scale phase traveltimes relatively.
  • New plot function to show radiation pattern / azimuthal distribution of directivity effects for synthetics.
  • Snuffler: load StationXML via menu.
  • io.mseed: Adding option for STEIM2 compression.
  • Jackseis: Adding --output-steim option to control compression. Default compression changed to STEIM2.
  • YAML files can now include other YAML files, when loaded through guts.
  • Moment tensor objects can now also be initialized from east-north-up coordinates.

Fixed

  • Fix plotting issues in cake.
  • Update Geofon catalog to handle MTs correctly after Geofon web page update.
  • Fix typos in STA/LTA documentation.
  • Fomosto PSGRN/PSCMP backend: improved control of modelling parameters, fixes some accuracy issues, regarding the spacial sampling interval.
  • Fomosto PSGRN/PSCMP backend: fixed scaling of isotropic GF components
  • Improved handling of differing sampling rates and interpolation settings when modelling multiple targets in gf.Engine.process.
  • PyQt compat issues with MacOS Big Sur.
  • Fix of gf.SFSource.discretize_basesource.

Changed

  • GmtPy now forces PDF version 1.5 when producing PDFs (newer PDFs caused problems when included in XeLaTeX).
  • QuakeML: Not strictly requiring preferred origin to be set anymore when extracting Pyrocko event objects.
  • Snuffler now asks for confirmation when the user attempts to close the window.

[2020.10.26]

Fixed

  • Fix errors with corrupt WADL returned by GEONET FDSN web service.
  • Fix cake crashes related to the --distances argument on newer NumPy/Python3.8.

Changed

  • Changed default of demean argument to Trace.transfer from False to True, to be consistent with the behaviour before the introduction of that flag.

[2020.10.08]

Added

  • Support for rotational seismograms in GF stores and Fomosto QSSP2017 backend.
  • Trace objects now support serialization to YAML and inclusion into Guts based objects.

Fixed

  • Fix incorrect conversion from displacement to velocity and acceleration in seismogram synthesis in pyrocko.gf. The problem occured when quantity='velocity' was selected in a pyrocko.gf.Target with a GF store with stored_quantity='displacement'. The returned amplitudes were incorrect except for the case of 1 Hz GFs.

Changed

  • Installation of prerequisites is now possible with a separate script install_prerequisites.py rather than through setup.py install_prerequisites.

[2020.08.18]

Added

  • Respect sensor azimuth and dip when converting RESP to StationXML.
