======
Changes:
- obspy.core:
* response: allow recalculating overall sensitivity even if unit type is not
one of VEL/ACC/DISP (see #3235)
* trace: 5x quicker retrieval of seed-id with trace.id / trace.get_id()
(see #3251)
* inventory: additional formatting tweaks to expanded channel information
(see #3261)
* read(): better support for reading from file-like objects in many plugins
(see #3346)
* allow to specify Trace and Stream filter frequencies as arguments
(see #3294)
* improve error messages when traces fail to get merged due to differing
data type, sampling rate etc (see #3418)
* add helper methods to change/unify byteorder on trace/stream (see #3418)
* window 'slepian' was removed in Trace/Stream.taper() as it was removed
from scipy with version 1.6, add new window 'dpss' that scipy promotes as
replacement but might need other parameters passed in (see #3331)
* util: removed old and outdated 'CatchWarnings' context manager in favor of
the better 'CatchAndAssertWarnings' context manager (see #3452)
- obspy.clients.filesystem:
* tsindex: update syntax for SQLAlchemy 2.0 compatibility (see #3269)
* tsindex: leap second handling was deactivated as it is not needed with
current msindex (see #3403)
- obspy.clients.fdsn
* Natural Resources Canada (NRCAN) added to list of known clients
* A FDSNNoServiceException is now raised instead of a ValueError when
querying a webservice not present in Client.services (see #3483)
* make sure to use a copy of `DEFAULT_SERVICES` when initializing a client
instance while skipping service discovery, to avoid accidental changes to
`DEFAULT_SERVICES` (see #3493)
* make it possible to opt out of server side gzip compression (see #3469)
* fix a regression introduced by #3306 which lead to some network errors not
getting raised as an FDSNException but some low-level exceptions like
AttributeError, which in turn caused problems in Mass Downloader (see
#3513)
- obspy.clients.seedlink:
* fix a bug in basic client `get_info()` which leaded to exceptions when
querying with `level="channel"` in presence of stations with no current
data available. Also, stations without data are now excluded from the
results. See docs for `get_info()` for information how to see the excluded
stations (see #2808)
- obspy.io:
* add read and write support for CSV, EVENTTXT and CSZ formats (see #3285)
- obspy.io.cybershake:
* add read support for CyberShake seismogram format (see #3370)
- obspy.io.mseed.spread_time_over_file:
* new routine to spread a time interval progressively across all mseed
blockettes in a file (see #3271)
- obspy.io.nlloc:
* set origin evaluation status to "rejected" if nonlinloc reports the
location run as "ABORTED", "IGNORED" or "REJECTED" (see #3230)
* store "NLLOC" info header line in event and origin comments (see #3230)
* add reading of confidence ellipsoids (see #3350)
- obspy.io.sac:
* fix floating point accuracy issues in sampling rate when reading some SAC
files. when reading SAC files, the sample spacing interval read from file
will now by default be rounded to microseconds before taking the
reciprocal to set the sampling rate. This can be deactivated using
"read(..., round_sampling_interval=False)" (see #3408)
- obspy.io.seg2:
* Less strict date/time parsing (#3283).
- obspy.io.seiscomp:
* add seiscomp scxml 0.13 support (see #3345)
- obspy.io.xseed:
* Improve error message when trying to read a local path to a file that does
not exist with XSEED Parser (see #2686)
- obspy.signal:
* all butterworth filters: correct zero-phase filtering of 2-d arrays and
filtering along non-default axis of 2-d arrays (see #3291)
* fix naming of input args in function "rotate_rt_ne()" (see #3383)
* add support for Chebyshev I/II, elliptic and Bessel filters alongside
the default Butterworth filters (see #3294)
1.4.1 (doi: 10.5281/zenodo.11093256)
====================================
Changes:
- obspy.core:
* fix a bug in response calculation with non-SI input units. With e.g.
"nm/s" as first stage input units (which is unusual, though), the
amplitude of the frequency response was calculated wrongly, not taking
into account the scaling factor needed to get from "nm/s" to "m/s". In
general if this bug would have been encountered before it should have led
to quite obviously wrong results, since it would lead to values that would
have been off by at least two orders of magnitude (e.g. in case of "cm/s")
or even up to nine orders of magnitude (e.g. in case of "nm/s").
(see #3369)
* fix a bug in Stream.select(inventory=...) (see #3282)
* fix a problem in Stream.plot() failing to remove the "min-max-plot zoom
warning" when interactively zooming into and then again out of a plot with
reduced number of points plotted with matplotlib >=3.6 (see #3318)
* fix an issue with Stream.rotate() when there are dots in e.g. station code
(see #3373)
- obspy.clients.fdsn:
* update URLs for FDSN web services raspberryshake, ISC and LMU (see #3264,
and #3413)
* properly include server response in error messages on bad requests (see
#3306)
* IRIS/Earthscope: fix all "catalogs" and "contributors" being suffixed with
'\n ' (see #3438)
* IRIS is now Earthscope. Adjusted all mention in docs accordingly and using
'IRIS' as short URL in FDSN client initialization as well as using
'iris-federator' in FDSN routing client initialization will show
deprecation warnings to use 'EARTHSCOPE' and 'earthscope-federator'
instead, respectively, but both old namings will still work (see #3448 and
#3456)
- obspy.clients.iris:
* IRIS is now Earthscope. Adjusted all mention in docs accordingly. The
module name will stay as 'obspy.clients.iris', though, to avoid breaking
users' codes (see #3448 and
#3456)
- obspy.clients.nrl:
* better handling of individual stages units when combining sensor and
datalogger response from a full downloaded offline version of the new NRL
v2 (see #3315, #3395)
* add support to use new categories "integrated" and "soh" in new NRL v2
(see #3315)
- obspy.clients.seedlink:
* avoid unnecessary calls to "get_info()" on waveform requests without
wildcards (see #3232)
- obspy.imaging:
* fix a bug that raised an error when plotting beachball patches with
routine "beach" with providing an existing axes instance (for proper
scaling) and saving to vector graphics as pdf/eps (see #2887)
* fix a problem in Stream.plot() failing to remove the "min-max-plot zoom
warning" when interactively zooming into and then again out of a plot with
reduced number of points plotted with matplotlib >=3.6 (see #3318)
* fix some issues with bad x-tick positioning and labeling in dayplots
(see #3361)
* fix a bug in Stream.plot() where the plotting method argument (e.g.,
'fast', 'full') was ignored for section-type plots
- obspy.io.gcf:
* Fixed an issue in algorithm to split and encode last few data into GCF
blocks (see #3252)
- obspy.io.sac:
* Fix writing SACPZ from poles and zeros stages with Hertz transfer function
type. SAC is expecting the SACPZ data to be in radians/s (see #3334)
- obspy.io.wav:

1.4.0 (doi: 10.5281/zenodo.6645832)
===================================
Changes:
- obspy.core:
* Minimum supported Python version is now 3.8 (see #3081, #3087)
* Minimum supported dependency versions are now numpy 1.20, scipy 1.7 and
matplotlib 3.3 (see #3081, #3087)
* response: avoid reporting all unkown units (e.g. "RAD/S") to evalresp as
displacement ("DIS") which with default value for "output" ("VEL") leads
to evalresp adding a differentiation during response calculation. Instead
report undefined unit, which makes evalresp use response as is and
essentially ignoring "output" parameter (see #2945)
* Improved expanded channel information in string representation of Station,
e.g. when displaying station in IPython shell (see #3024)
* limit length of list which records processing info (see #2882)
* map plots: fix initial map setup, properly pass through user specified
options, like "projection" etc (see #3191)
- obspy.clients.fdsn:
* update URL for NCEDC to https (see #3203)
* add all valid parameters to get_stations_bulk, e.g. geographical
constraints (see #3140)
* do not use autodiscovery of file format in get_stations, unless "format"
is set to something we do not recognize (see #3138)
* fix a bug in routing client that made any request made error out when
"debug=True" was set (see #3214)
* fix raising FDSNTooManyRequestsException when server rejects request due
to rate limiting, due to a bug instead a TypeError was raised (see #3219)
- obspy.clients.seishub:
* submodule removed completely, since it is outdated and not even test
servers have been running for years (see #2994)
- obspy.db:
* submodule removed completely, since mostly being used in discontinued
seishub server (see #2994)
- obspy.imaging:
* spectrogram: change the computation for default window length if not
specified to give useful values for sampling rates much higher or lower
than 100 Hz (see #3093)
* spectrogram: better exception type and messages when input signal is too
short (see #3093)
* map plots: fix initial map setup, properly pass through user specified
options, like "projection" etc (see #3191)
- obspy.io.alsep:
* new module for reading data from the Apollo missions stored in ALSEP
format (see #3156)
- obspy.io.nlloc:
* avoid mangling channel/component code when writing nonlinloc phase file,
just write full channel code unchanged into nonlinloc's "component" field
(see #3223)
* fix reading nonlinloc hypocenter files written by newer nonlinloc
versions, data parsed into Arrivals was wrong (see #3223)
* read geometrical station azimuth instead of ray takeoff azimuth from
hypocenter. This is more robust (ray takeoff values sometimes not accurate
at all) and also follows more the QuakeML documentation that states
"Azimuth of station as seen from the epicenter" which implies a simple
geometrical calculation (see #3224)
* ignore ray takeoff dip if the stated quality for it is "0 - unreliable".
our example data show that values can be blatantly wrong when quality is
reported as "0" (see #3224)
* write timing error as "0.0" if it is not set on a pick, as recommended by
nonlinloc's author (see #2371, #3224)
- obspy.io.nordic:
* add support for writing multiple amplitudes for one pick (only new format)
and writes some amplitude lines more compact (see #3075, also #2814)
* add full support for reading and writing apparent velocity and backazimuth
with new nordic format (see #3075)
* fix comments on angle of incidence vs. takeoff angle (What is called
angle of incidence in Seisan is the same as what is usually referred to as
takeoff angle, see #3075)
* add function to check whether phase is valid IASPEI phase in Seisan (#3075)
* full support for writing high-accuracy origin line (see #3075)
- obspy.io.sac:
* expose a `keep_sac_header` flag to the `write` plugin, which allows users
to write a "fresh" SAC header, instead of attempting to merge information
from an old SAC header, if one exists. (see #2760)
* fix writing SACPZ when a channel's sensor filed is unset (see #3187)
- obspy.io.seiscomp:
* update SeisComP 0.11 and 0.12 schema to potentially speed up sc3ml to qml
event catalog conversions (see #3216 and SeisComP/common#74)
- obspy.signal:
* coincidence trigger: improve speed of template matching and less memory
usage (see #3104)
* added energy_ratio and modified_energy_ratio trigger methods (see #3161)
* Baer picker: fix a bug that could cause crashes on certain versions of
libffi (see #3183)
* polarization analysis: fix calculation of timestamps of the resulting
values (see #3211)
- obspy.taup:
* add option "indicate_wave_type" to distinguish S waves in ray paths
plot by using wiggly lines for shear waves (see #3047)
* improved accuracy of ray paths by change of root-finding algorithm
in SeismicPhase.refine_arrival (see #3064, #3096)
* improved accuracy of travel time estimates by using theta function
(see #3068)
* add support for models without a core or inner core
(see #1200, #1423, #2086, #2192, #2390, #3070)
* add support for a wider range of diffracted phases, like SedPdiffKP
(see #3085) and PKdiffP (see #3095)
* allow rapid travel time plotting in plot_travel_times by using
precalculated travel times (see #3092)
* return pierce points for any depth (see #1742, #3072)
* bug fix for rays which cannot turn due to low velocity at bottom
of layer (see #3080)
* add some checks for bad phases, so "ScScS" is not allowed
(see #2774, #3082)
* bug fix for sources within high slowness regions (see #2976, #3100)

(see #3158)
* add URL mapping 'EIDA' for http://eida-federator.ethz.ch (see #3050)
* Fix issue where "https://" URLs were not matched by the IRIS federator
client, resulting in raspberry shake matches being excluded from results
(see #3127)
* Properly set HTTP Content-Type header in POST requests (see #3169)
- obspy.clients.nrl:

1.3.0 (doi: 10.5281/zenodo.6327346)
===================================
Changes:
- obspy.*
* no more support for Python 2 (see #2577)
* added python 3.9 and 3.10 tests for all platforms,
minimal supported python version is 3.7 (#2925, #2489)
* removed os.path calls with pathlib library calls (see #2751).
* rewrote CI tests to make use of cache (see #2936)
* removed individual logging configurations in Obspy, logging can be
configured by the user, see documentation of Pythons logging module,
only the FDSN mass downloader automatically configures logging as before,
but this behavior can be turned off now. The loglevel keywords are
therefore deprecated and have no effect anymore (see #2720)
* refactored obspy-runtest to use pytest and modified several command
line arguments, required to disable image comparisons (see #2489)
* removed calls to deprecated NumPy functionality (see #2949, #2981)
* cleaned the documentation, build process, and docstrings (see #2662, #2954)
* refactored and modernized setup.py (see #2422)
- scripts:
* SDS report: try to be faster on slow filesystems (see #3009)
- obspy.core:
* speed up import of obspy core functions (see #2758)
* read_inventory(): add "level" option to read files faster when less level
of detail is needed. currently only implemented for StationXML reading
(see #2759)

instrument response (see #2677)
* round magnitudes in Catalog/Event string representation to one decimal
(see #2742)
* add support for pathlib.Path objects in read(), read_inventory() and
read_events() functions (see #2743)
* add a "DEF" option (default units) to Inventory.plot_response() and
Trace.remove_response() (see #2806)
* stream.select(): circumvent wildcard-matching when called with a trace-id
without wildcards for quicker trace selection.
* Inventory addition now consistently uses shallow copies (#2675, #2694)
* removed obsolete wrapper around numpy.loadtxt causing import error with
numpy 1.22 (see #2912, #2913)
* fix iso8601 regex for issue #2868 to cope with day 360 properly
* fix crash when resampling very short traces (see #2926)
* response list stages: do not raise an exception if response calculation
involves extrapolation outside of frequency range defined by the response
list stage but rather only show a warning. raising an exception is the
safe route but it also prevents valid calculations as it is up to the user
to make sure that signal spectrum is properly suppressed in those
frequency ranges outside of the valid response information (see #2988)
* fix a bug while checking for valid URI syntax when setting identifiers on
inventory type objects (see #2905)
* fix a bug unpacking strings while reading event comments of AH files
(see #3107)

- obspy.clients.filesystem:
* add get_waveforms_bulk() method to SDS client (see #2616, #2626)
* SDS client get_latency(): make one internal check optional which can be a
massive speedup on slow filesystems (see #3009)
- obspy.clients.seedlink:
* basic client: properly terminate after finished get_info() request (see
#2996)
- obspy.imaging:

* open CSS waveforms even if gzip-compressed (see #2736)
- obspy.io.gcf:
* Replaced pure Python code base with C source code base updated to latest
revision of GCF format at time of writing (see #3055, April 2022)
* Added write support for GCF (see #3055)
* Added utility functions to check if a sampling rate or start time are
compatible with format restrictions (see #3055)
- obspy.io.gse2:
* When reading GSE2 bulletins, station magnitudes now include waveform IDs
and have associated station magnitude contributions (see #2718)
- obspy.io.hypodd
* add PHA write support (see #2687)
* add read support for horizontal and vertical origin uncertainty (see #2687)
- obspy.io.kinemetrics:
* adds the ``apply_calib`` argument to the ``read_evt`` method to allow
obtaining the raw data bits stored in the evt file (see #2582), note this
changes the default (wrong!) behaviour, by default the data returned will
be the NOT corrected ones. When passing ``apply_calib=True``, the
calibration factor will be used.
- obspy.io.nordic:
* add read and write support for New Nordic format (see #2814)
* fix bug where negative magnitudes were not read properly
* fix bug where empty hours / minutes / seconds were not read as zero

instead.
- obspy.io.reftek:
* enable reading data with floating point sampling rates like low sampling
rate state-of-health channels (see #2678)
* fix reading data in '16' and '32' encodings, when packets do not use
the fixed maximum amount of available number of samples per data packet
(see #2678)
* properly take into account native system byteorder, should fix reading
rt130 data on big endian systems (see #2678)
- obspy.io.seiscomp:
* Add support for SC3ML 0.11 and 0.12, dropped support for SC3ML < 0.6
(see #2284).
* Add support for custom tags (see #2284).
- obspy.io.sh:
* fix appending traces to existing Q file (see #2870)
- obspy.io.xseed:
* fix a bug reading SEED blockettes 48 and 58 which was likely never
encountered (see #2668)
* Properly read a given value of 0.0 in station elevation and not replace it
with bogus value (see #2763)
- obspy.signal.array_analysis
* fixed an issue in array_processing function returning wrong times
for matplotlib versions >= 3.3 due to the epoch change in matplotlib
(see #2723)

data when requesting an invalid, out-of-epochs time window for a valid
station (see #2611)
* update RASPISHAKE URL mapping to use https
* fix a bug of not handling HTTPException in mass_downloader (see #2606)
* use the client's set timeout in service discovery, too (see #2656)
* add URL mapping for FDSNWS at UIB-NORSAR (see #2659)
- obspy.clients.filesystem:

Changes:
- obspy.core:
* Inventory objects have been adapted to StationXML 1.1 for details on
changes see #2510 and
https://github.com/FDSN/StationXML/blob/master/Changes.md
* Fixed import of custom plugins (see #2423)
* Fixed "==" comparison for Stream and Trace which was very slow in case of
traces with >1e6 samples (see #2377)
* Added almost_equal method for Stream and Trace classes (see #2286).
* Casting FDSN identifiers to strings upon setting in the stats dictionary
(see #1997).
* UTCDateTime objects will now always evaluate equal if their string
representations are equal (see #2049).
* UTCDateTime objects now issue depreciation warnings when setting any
attributes outside of init, or comparing UTCDateTime objects with
different precisions (see #2077).
* UTCDateTime objects can now accept hour, minute, second, and microsecond
values greater than their normal limits by setting the strict keyword
argument to False (see #2232).
* Fixed UTCDateTime(..., julday=366) for non-leap years. This was returning
January 1st of the next year in case of non-leap years being used. Now it
properly raises an out-of-bounds ValueError (see #2369)
* When reading StationXML/SC3ML, make sure to properly read empty string
fields as empty strings instead of "None" (see #2519 and #2527)
* Better ISO8601 detection for UTCDateTime objects and UTCDateTime(...,
iso8601=False) now completely disables ISO8601 handling (see #2447)
* Added replace method to UTCDateTime class (see #2077).
* Added remove method to Inventory class (see #2088).
* Added id property to WaveformStreamID (see #2131).
* Added __str__ and _repr_pretty_ method for Comment class (see #2115)
* Added __eq__ to QuantityError so empty instances equal None (see #2185).
* Reworked the event scoped resource identifiers for the event classes
hopefully fixing all edge-cases (see #2091).
* Added a hook to allow users to customize finding objects for
resource_ids which are not found via the normal means (see #2279).
* Calling Stream.write(...) on an empty stream will now raise an
ObsPyException consistently across all I/O plugins (see #2201)
* Stream.get_gaps() will now properly report gaps within Traces that
have masked arrays (i.e. Traces that have been merged without a fill
value, see #2299 and #2300).
* Added copy method to Inventory class (see #2322).
* The Response.recalculate_overall_sensitivity() method now accepts integers
(see #2338, #2343).
* Added wildcard and url support to read_inventory (see #2326).
* Modified stream.get_gaps() to deal with overlaps correctly (see #1403)
* Added option "label_epoch_dates" to Inventory/Network.plot_response() to
optionally add channel epoch start/end dates to legend labels (see #2309)
* Deprecated the convert_id_to_quakeml_uri, regenerate_uuid, and
get_quakeml_uri methods of the ResourceIdentifier class (see #2303).
* Added get_quakeml_uri_str and get_quakeml_id methods to the
ResourceIdentifier class (see #2303).
* New method to create response objects directly from poles and zeros (see
#1962).
* Added Stream.stack method (see #2440).
* Added a component field to the Stats object which allows to get and set
the last character of the SEED channel (see #2484).
* Fixed a bug in Stream.plot(type='section', reftime=..., ...) that caused
wrong relative start times of traces relative to given reftime (see #2493)
* Fixed a Windows-specific path case issue in a helper function that returns
a list of untracked files in the git repository (see #2296)
* Fix a bug that was causing an exception being raised in `Response.plot()`
because a float was being passed down to numpy.linspace as length of array
(see #2533)
* Geographic select of inventory/network/station (see #2515)
* Select traces in Stream based on an Inventory (see #2531)
- obspy.clients.fdsn:
* Add new `_discover_services` boolean flag to the Client, which allows the
Client to skip the initial services query at instantiation. This can
reduce the load on service providers, but skips checks against unsupported
query parameters.
* Adding more location codes to the default priority list in the mass
downloader (see #2155, #2159).
* The mass downloader now raises a warning if all channels from a station
have been deselected due to the default location priorities setting. This
is a pure usability improvement as it has been confusing users
(see #2159).
* Make sure that streams fetched via FDSN are properly trimmed to user
requested times if data center serves additional data around the start/end
(see #1887, #2298)
* Fix a problem that could spam subprocesses that were not closed in routed
clients (see #2342 and #2344)
* Make it possible to use signed EIDA tokens and also skip token validation
completely (see #2297)
* Adding a mapping for RASPISHAKE
- obspy.clients.filesystem.tsindex:
* Add new Client & Indexer modules based on IRIS time series index (see
#2206)
- obspy.clients.iris:
* Results of distaz method are now returned as native floats (see #2499)
- obspy.clients.neic:
* Properly use specified timeout value (see #2450)
- obspy.clients.seedlink:
* Add method "get_info()" to fetch information on what
networks/stations/locations/channels are served by the seedlink server
(see #2405)
* "get_waveforms()" can now be used with '*' and '?' wildcards in any part
of requested SEED ID, i.e. network, station, location and channel (see
#2405)
- obspy.clients.seishub:
* Properly handle fetching poles and zeros in presence of multiple metadata
files for a given station (see #2411)
- obspy.geodetics:
* New utility function `inside_geobounds()` to check whether an object is

array of sampletimes in various different timing varieties ("relative":
the old default, float relative to trace starttime or `reftime` in

`UTCDateTime.timestamp`; "matplotlib": array of float matplotlib dates,
useful for plotting on matplotlib time axes; see #1307)

#1685).
* Adding mappings for the TEXNET (see #1852) and the ICGC (see #1902)
services.
