obspy: 0.10.0

After over 2200 commits from 25 contributors ObsPy 0.10.0 is finished and has been released.

The new key features are support for Python 3, a slew of new file formats, and a new TauP implementation.

  • Preview waveform plot improved: interactive updating of ticks and ticklabels, correct ticklabels for sub-minute zoom level (#657)
  • fixed a problem with UTCDateTime with timestamps of far future dates (larger than 2038, often seen in StationXML end dates, see #805)

  • Renamed 'type' argument to 'method' in the Trace.integrate() method. Additionally, several broken alternate methods have been removed.
  • new plugins for NonLinLoc formats for readEvents() and Catalog/Event.write() (see obspy.nlloc and #900)
  • The wrap_long_string utility function is deprecated. Users may use the textwrap module which provides similar functionality.

  • better customizable control during merging traces with sub-sample shift of sampling points (see #980)
• obspy.cnv:

• obspy.imaging:
  • Maintain beach ball aspect ratio through optional axes argument (see #734)
  • Refactored Catalog.plot() into helper routine obspy.imaging.maps.plot_basemap() (see #753).
  • The projections of Catalog.plot() have been modified slightly to provide equal-area projections:
    • The "cyl" projection is now named "global". It is now the Mollweide projection.
    • The '"local"` projection now uses the Albers Equal Area projection.
• obspy.kinemetrics
  • New submodule for reading the Kinemetrics EVT waveform format
• obspy.mseed:
  • Support for reading and writing all encodings supported by libmseed.
  • proper error reporting while reading
  • details=True when reading will now write to Trace.stats.mseed.blkt1001.timing_quality instead of Trace.stats.mseed.timing_quality.
  • The timing quality will now also be written to a file if it is set.
  • Non-existing values when reading with details=True will now be set to False instead of -1.
  • New utility function obspy.mseed.util.set_flags_in_fixed_header() giving the ability to overwrite flags in the fixed header of existing MiniSEED files.
  • The sequence number of the first record of each Trace can now be specified when writing MiniSEED files.
  • obspy-mseed-recordanalyzer:
    • Bugfix: when specifying an out-of-bounds record number, information about the last record in the file was displayed (see #957). Now a proper error message is shown and the command line script exits with non-zero exit code.
    • Faster reading of a single record header
