    What's New in ObsPy 1.1

    Full Changelog

    1.1.0: (doi: 10.5281/zenodo.165135)
     - General:
       * Read support for Guralp Compressed Format (GCF) waveform data,
         obspy.io.gcf (see #1449)
       * Read support for Reftek 130 (rt130) waveform data,
         obspy.io.reftek (see #1433)
       * Add Nordic format (s-file) read/write (see #1517)
       * Read and write support for events in the SCARDEC catlogue format
         (see #1391).
       * Read support for IASPEI ISF ISM 1.0 Bulletin event data,
         (see #1946)
       * Write support for AH (Ad Hoc version 1) format (see #1754)
       * Client to access the Nominal Response Library (NRL) (see #1185).
       * `obspy.read_inventory()` can now read dataless SEED and RESP files
         (see #1185).
       * change version number scheme for scenarios when no official version number
         can be determined (see #1889 and #1916)
       * Support for the IRIS Federator and EIDAWS FDSNWS web routing services
         (see #1779 and #1919).
     - obspy.core:
       * UTCDateTime is now based on nanoseconds (long) instead of a unix
         timestamp in microseconds (float) - resulting in higher precision and
         support for years 1-9999 (see #1325)
       * Ensure that Trace.data is always C-contiguous in memory (see #1732)
       * Event/ResourceIdentifier is now object aware, meaning even if two
         objects share a resource_id the distinct objects will be returned with
         the get_referred_object method provided both are still in scope. If one
         of the objects gets garbage collected, however, a warning will be issued
         and the behavior will be the same as before (see #1644).
       * Better error message when attempting to write invalid QuakeML resource
         ids (see #1699).
       * Stream/Trace.write() can now autodetect file format from file extension
         (see #1321).
       * New convenience property `.matplotlib_date` for `UTCDateTime` objects to
         get matplotlib datetime float representation (which can be used in
         time-based matplotlib axes, e.g. by Stream.plot(); see #1339).
       * Trace.times() has new options `type` and `reftime` to support fetching an
         array of sampletimes in various different timing varieties ("relative":
         the old default, float relative to trace starttime or `reftime` in
         seconds; "utcdatetime": absolute times as UTCDateTime objects;
         "timestamp": array of float POSIX timestamps, compare
         `UTCDateTime.timestamp`; "matplotlib": array of float matplotlib dates,
         useful for plotting on matplotlib time axes; see #1307)
       * A trace's stats.network/station/location/channel can now also be set in
         one line using a SEED ID string (e.g. `trace.id = "GR.FUR..HHZ"`,
         see #1439).
       * Instrument correction for response list stages originating from inventory
         objects (see #1514).
       * `Stream.rotate(...)` can now also be used to rotate unaligned channels to
         Z-N-E, given an Inventory (see #1310)
       * Non finite floats (NaN, inf, -inf) can now no longer be set for all
         event objects (see #1597).
       * Instrument responses can now also be calculated for a given list of
         frequencies (see #1598).
       * Order of extra tags for event type classes serialized to QuakeML can now
         be controlled by using an OrderedDict (see #1617)
       * Bode plots can now optionally plot the phase in degrees (see #1763).
       * `Stream.select()` now also works on the component level if channels only
         have one letter (see #1847).
       * Now strips all invalid characters from the temporary filenames used for
         downloading data using the `read_X()` methods (see #1958).
     - obspy.clients.earthworm:
       * Much faster trace unpacking (see #1762).
     - obspy.clients.fdsn:
       * empty SEED codes (e.g. ``network=''``) will now be properly sent to the
         server as options and not omitted, which led to wildcard matching (for
         details see #1578)
       * The mass downloader now has `exclude_networks` and `exclude_stations`
         arguments to not download certain pieces of data. (see #1305)
       * The mass downloader can now download stations that are part of a given
         inventory object.
       * The mass downloader now also works with restricted data. (See #1350)
       * No data (HTTP 204) responses now raise `FDSNNoDataException` rather than
         the more general `FDSNException`.
       * Fixing cross implementation of bulk waveform and station requests (see
         #1685).
       * Adding mappings for the TEXNET (see #1852) and the ICGC (see #1902)
         services.
       * Support for the non-standard EIDA token authentication (see #1928).
     - obspy.imaging:
       * The functionality behind the `obspy-scan` command line script has been
         refactored into a `Scanner` class so that it can be reused in custom
         workflows. (see #1444)
     - obspy.imaging.cm:
       * new colormap: viridis_white. This is a modification of viridis that
         goes to white instead of yellow but remains perceptually uniform. It
         is especially useful for printing when an image should merge with the
         white background.
     - obspy.imaging.waveform:
       * Support for filling the wiggles when plotting sections (horizontal and
         vertical, see #1445).
     - obspy.io.arclink:
        * Read support for Arclink Inventory XML (see #1539)
        * default for `route` parameter in metadata requests is changed to `False`
          (see #1756)
     - obspy.io.ascii:
        * Custom formatting of sample values when writing SLIST and TSPAIR.
     - obspy.io.datamark:
        * Renamed without deprectation to obspy.io.win to match its original name.
          Datamark is a datalogger, saving the WIN format.
     - obspy.io.gse2:
        * Read support for GSE2.0 bulletin (see #1528)
     - obspy.io.nlloc:
        * Also parse author information and COMMENT line (see #1484)
        * Fix reading hypocenter files created by NonLinLoc versions of the 6.0.x
          beta branch (see #1760 and #1783)
     - obspy.io.quakeml:
        * Read and write support for nested custom tags (see #1463)
        * Fix some minor bugs that could lead to empty stub elements, e.g. like
          empty MomentTensor when reading and later writing again a QuakeML file
          with a FocalMechanism but no MomentTensor, potentially resulting in
          QuakeML files that breach the QuakeML schema (see #1896)
     - obspy.io.seiscomp:
        * Read and write support for SC3ML event (see #1638 and #1848)
        * Fix bug where files with arbitrary publicIDs and files with missing
          depth, latitude, longitude, or elevation tags could not be read
          (see #1817)
     - obspy.io.stationtxt:
        * Write support for stationtxt format (see #1466)
     - obspy.io.stationxml:
        * Read and write support for custom tags (see #1024)
        * No longer add the (unused) time zone field to StationXML datetimes to
          follow the example of big data centers. (see #1572)
        * Level of detail can be specified during inventory write (see #1830)
          using the level keyword (one of: network, station, channel, response).
        * Skip empty and incomplete channels during reading (see #1839, #1840).
     - obspy.io.segy:
        * Fixing an issue when comparing two still packed SEG-Y trace headers
          (see #1735).
        * Iterative reading of large SEG-Y and SU files with
          `obspy.io.segy.segy.iread_segy` and `obspy.io.segy.segy.iread_su`.
          (see #1400).
        * Write correct revision number (see #1737).
        * Textual headers will now always contain the file revision number and the
          end header mark if nothing else exists at these positions (see #1738).
        * The SEG-Y format detection now also checks the format version number
          (see #1781).
        * Enable reading SEG-Y files that have day of year 0 in trace header
          (see #1722).
        * Write textual file headers also if given as a text string
          (see #1811, #1813).
     - obspy.io.css:
       * Read support for NNSA KB Core format waveform data. (see #1332)
     - obspy.io.mseed:
       * New generic get_flags() utility function able to retrieve statistics
         about all fixed header flags and the timing quality. This makes the
         get_timing_and_data_quality() function obsolete which is thus
         deprecated and will be removed with the next release. The get_flags()
         function is also much faster. (see #1141)
       * Always hook up the libmseed logging to its Python counterpart to avoid
         some rare segfaults. (see #1658)
       * Update to libmseed v2.19.5 (see #1703, #1780, #1939).
       * Correctly read MiniSEED files with a data offset of 48 bytes (see #1540).
       * InternalMSEEDReadingError now called InternalMSEEDError and
         InternalMSEEDReadingWarning now called InternalMSEEDWarning as both
         can now also be raised in non-reading contexts (see #1658).
       * Should no-longer segfault with arbitrarily truncated files (see #1728).
       * Will now raise an exception when attempting to directly read mini-SEED
         files larger than 2048 MiB (#1746).
       * `.stats.mseed` attributes are no longer per-file but per-trace where
         applicable (see #1782).
       * `get_record_information()` - Don't fail if the word order is invalid.
     - obspy.io.nlloc:
       * Set preferred origin of event (see #1570)
     - obspy.io.nordic:
       * Add Nordic format (s-file) read/write (see #1517)
     - obspy.io.win:
       * see obspy.io.datamark.
     - obspy.io.xseed:
       * Added azimuth and dip to the get_coordinates() function. (see #1315)
       * Fixing some issues with the get_resp() output on Python 3 (see #1748).
       * Can now also parse RESP files (see #1185).
       * Can transform responses in the Parser object to ObsPy Inventory objects
         (see #1185).
     - obspy.scripts:
       * obspy-scan command line script now also plots and prints overlaps
         alongside gaps (see #1366)
       * obspy-plot now has option to disable min/max plot (see #1583)
     - obspy.signal:
       * fixed a bug in calibration.rel_calib_stack (resulting amplitude response
         had wrong scaling if using non-default "overlap_fraction", see #1821)
       * fixed a bug in coincidence_trigger() with event templates. when a template
         with mismatching SEED ID was encountered all following (potentially valid)
         templates were skipped as well (see #1850)
       * New obspy.signal.quality_control module to compute quality metrics from
         MiniSEED files. (see #1141)
       * New correlate function for calculating the cross-correlation function
         (new implementation based on Scipy).
         To calculate the shift of the maximum of the cross correlation use
         xcorr_max. The old xcorr function is deprecated but currently still
         exists (see #1585).
       * New obspy.signal.regression module to compute linear regressions, with or
         without weights, with or without allowing for an intercept. (see #1716,
         #1747)
       * add new plotting capabilities to PPSD (temporal variations per frequency
         and spectrogram-like plot) and also make underlying processed PSDs
         available via `PPSD.psd_values` property (see #1327)
       * Fixed bug in `rotate2zne()` for non-orthogonal configurations
         (see #1913, #1927).
       * Fixed build warnings in evalresp, partially backported from evalresp
         4.0.6 (see #1939).
     - obspy.taup:
       * Add obspy.taup.taup_geo.calc_dist_azi, a function to return the distance,
         azimuth and backazimuth for a source - receiver pair. (see #1538)
       * Fixing calculations through very small regional models. (see #1761)
       * Updated ray path plot method, added travel time plot method, and wrapper
         functions for both ray path and travel time plotting. (see #1501, #1877)
