0.8.3

• circumventing an issue in the current libmseed release that can lead to
  some float values being read in wrongly

0.8.2

• fixing a bug in plotting methods of Trace and Stream
• stream/trace.plot(type="dayplot") can display event information now

0.8.1

• fixing a bug parsing QuakeML from a StringIO object using xml and
  autodetection

0.8.0

• general:
  • version numbering: one single, common version number for ObsPy now.
    Use "import obspy; print obspy.version"
  • discontinuing Python 2.5 support
  • most important classes/functions can be imported like "from obspy import
    ...", currently: read, Trace, Stream, UTCDateTime and readEvents
• obspy.arclink:
  • refactored attributes in getPAZ to stick better with the SEED standard
• obspy.core:
  • fixing preview generation for sampling rates containing floats
  • fixing deprecated_keywords decorator for the case of removed keywords
  • fixing SLIST and TSPAIR reading/writing of empty traces or traces
    containing only one or two data points
  • adding taper() method to Trace/Stream using cosTaper of ObsPy and also
    all scipy windowing functions
  • adding cutout() method to Stream
  • removed all deprecated UTCDateTime methods
  • adding a class and script to determine flinn-engdahl regions for given
    longitude and latitude
  • adding rotate() method to Stream wrapping rotate functions in
    obspy.signal
• obspy.imaging:
  • obspy-scan: adding options to control start/endtime and channels, adding
    options to not plot gaps and reducing file size for plots considerably.
• obspy.iris:
  • output format 'bulk' for Client.availability has been deprecated, use
    'bulkdataselect' instead (#419)
• obspy.mseed:
  • Bugfix writing traces containing one or two samples only
  • writeMSEED emits an UserWarning while writing an empty trace
• obspy.sac:
  • fixing SAC and SACXY reading/writing of empty traces or traces containing
    only one or two data points
  • new debug_headers flag for reading SAC files in order to extract all
    header variables (issue #390)
• obspy.segy:
  • unpack SEGYTrace.data on-the-fly patch contributed Nathaniel Miller
  • fixing a bug related to negative values in trace header
• obspy.seishub:
  • adding kwarg to control number of retries for failing requests
  • adding obspy.xseed as dependency (in setup.py and debian/control)
  • changing obspy.client.station.getPAZ() call syntax to use seed_id
    (args/kwargs)
  • adding local caching of requests for PAZ and coordinates to avoid
    repeated requests to server
• obspy.sh:
  • file extension 'QBN' not added twice anymore if data_directory was set
  • fixing SH_ASC and Q reading/writing of empty traces or traces containing
    only one or two data points
• obspy.signal:
  • module psd has been refactored to spectral_estimation
  • adding function for cross correlation pick correction
  • removing pitsa-compatibility in response function calculation
    (no complex conjugate)
  • preventing a possible duplicated overall sensitivity removal in seisSim
    when using the option seedresp
  • adding optimized C-code for classic STALTA. Runs approximately, 1000x
    faster than pure python code. It has now the same order of speed as the
    recursive STALTA
  • new CAPON method for array_analysis / array_processing
  • sonic was renamed to array_processing, sonic is now deprecated
• obspy.xseed:
  • fixed a bug with Dataless to XSEED conversion using split_stations=True
  • fixed a bug affecting getPAZ() and getCoordinates() when selecting
    specific channels from complex dataless files
    (see: #412)
  • added getInventory() method to the Parser object. Returns a dictionary
    about the contents of the Parser object. This is also integrated in the
    string representation and makes it more informative.
• obspy.mseed:
  • adding experimental details option, which extracts timing quality and
    info on the calibration
