Pyrocko

Fixed
- Fix compatibility with newer versions of NumPy and SciPy.
- Fix broken function pyrocko.client.fdsn.event.
- Fix broken YAML-serialization of `Trace` objects.
- Squirrel: fix problems in `get_stations` with `model='pyrocko'`
- Various minor bugs and typos fixed.

Added
- Squirrel:
- `squirrel jackseis`: new command line options: `--traversal`, `--tinc`
- Fomosto QSEIS backend: added support for qseis_2006b with adjustable source
disk radius. Setting this to zero allows calculating of seismograms which are
correct for low frequencies down to static displacement.
- Snufflings:
- Seismosizer: add single-force source model.
- Smartplot integration for improved MPL plot/figure layouting.
- New built-in Snuffling: Spectrogram
- Docs: add mini-tutorial on how to set up and use remote Snuffler through VNC.
- New function to get a Snuffler-like time axis in MPL plots
`pyrocko.plot.mpl_time_axis`
- Convenience script for Windows users to download and install MSVC build tools
15 from the command line.
- Pseudo-dynamic rupture model: add method to get centroid location.

Changed
- Squirrel: refactored Channel and Sensor classes, improved channel-to-sensor
logic.
- Snuffler: enlarged default filter ranges.
- Reimplemented TypeC (3D) GF store. To my knowledge this store type has not
yet been used in the wild, so felt free to improve the design.
- Default antialising FIR filter ``fir-remez`` now uses 45 x q taps instead of
40 x q.

Fixed
- *Important:* fixed buffer overflow error in `pyrocko.util.time_to_str`. This
one-byte buffer overflow occurred for time formats, when the format string
did *not* request fractional seconds to be appended, e.g. `'%Y-%m-%d
%H:%M:%S'`. It caused random crashes on macOS and, for longer format strings,
also on Linux. The error did not occur with the default `format` parameter of
`time_to_str`.
- Squirrel: various bug fixes and minor improvements.
- Automap: improved GMT6 support.
- Fix crash in `pyrocko.trace.degapper` with `fillmethod='zeros'`.
- Fix output channel naming in `pyrocko.trace.rotate_to_rt`.
- Snuffler:
- Now always uses locale-independent dates in time axis.
- Various appearance fixes.
- Prevent a confusing warning at startup on macOS.
- Snufflings:
- STA/LTA: fix error where markers were being inserted multiple times.
- Fix Snuffler crashes when exception is raised in trigger button calls.
- Much improved `pyrocko.plot.smartplot` module.
- Corrected conversion between volume-change and moment for VLVD and explosion
sources. Before, the approximation for a Poisson solid was used.

Added
- `squirrel jackseis`: new option: `--codes`
- `squirrel codes`: new options: `--codes`, `--kind`
- Squirrel pile emulation: support `chopper_grouped` method.
- Squirrel: support grouping in `chopper_waveforms` method.
- Running `python -m rdseed` now converts dataless to stationxml.
- Squirrel: new subcommands `remove promises`, `stationxml`.
- New Squirrel CLI tutorial.
- Support GMT6 in gmtpy and automap.

Fixed
- Fixed installation issues
- `install.py` called incorrect pip version,
- Improved platform detection.
- `install.py` now works on some older linuxes.
- Squirrel: various bugfixes and docs improvements
- Improved robustness of StationXML response handling.

Changed
- Snuffler: allow confirmation of ctrl-c on command line.
- Drop support for auto-persistent datasets (had confusing consequences).

Added
- New framework for seismological data access: `pyrocko.squirrel`
- New module `modelling.cracksol` containing different analytical crack
solutions for displacement and dislocation modelling.
- New extension `modelling.ext.okada_ext` following `Okada, 1992` to calculate
displacements and spatial derivatives.
- New module `modelling.okada` with `OkadaSource` object as wrapper of C
extension and inverter to estimate dislocation based on stress drop on a
rectangular rupture plane.
- New `gf.seismosizer.PseudoDynamicRupture` wrapping boundary element method
based on `modelling.okada.OkadaSource` combined with the Eikonal solver to
perform quasi-dynamic slip modelling.
- New plotting module for the `PseudoDynamicRupture` in `plot.dynamic_rupture`.
- New scenario `scenario.sources.pseudodynrupture` for usage of the
`PseudoDynamicRupture` as `colosseo` input.
- New `aggressive_oversampling` attribute for both `gf.RectangularSource` and
`gf.PseudoDynamicRupture` allowing for hard oversampling of the basesources.
- RMS Snuffling: Option to show log RMS.
- New example on how to create QuakeML files from scratch.
- automap: add flags to customize plate plotting and axes ticks
- Snuffler: live seismograms from DataCube.
- Improved responses module, more supported transfer functions, converters.
- Improved error handling and diagnostics when extracting responses from
StationXML.
- Functions to instantiate moment tensor from P and T axes.
- Examples for eikonal solver.
- Support for take-off angle and other precomputed tables in GF stores.
- Snuffler: add waterfall style for dense recordings like DAS.
- Snuffler: `goto today`, `goto yesterday` commands.
- Support reading of TDMS IDAS files.

Fixed
- Fix Snuffler crashes on reading invalid files and other IO related errors.
- Fixed `Trace.envelope`.
- Fixed `evalresp` platform detection.
- Fixed `MomentTensor.both_slip_vectors`, this function was broken completely.

Changed
- Drop support for Python < 3.5.
- Drop support for Qt4.
- Improvements to directivity plot.
- Renamed Snuffling "Block RMS" to "RMS".
- Fomosto QSEIS backend can now handle non-zero (negative) top layer depth,
e.g. for models including the atmosphere.
- Removed support for initial marker file format from before August 2011.
- New installation recommendations.
- Snuffler: two more marker kinds/colors (6, 7).
- Snuffler: migrated from right-click menu to regular menubar.

Changed
- Improved RMS and STA/LTA Snufflings (keep responsive while processing, abort
button, more options).

Added
- Reading of GNSS location information from datacube files.
- Jackseis: added possibility to restitute data to displacement, velocity, or
acceleration.

Fixed
- Fix problems with Station-XML files containing 1900-01-01 dummy dates
(macOS).
- Correct 'pyrocko-python' symlink on Linux which was broken in v2021.06.29
(affects grondown scripts).

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.
