Changes in this version:

Release v0.7

This version requires at least Python 3.9.

Note: you might want to run requake update_config to update your config file
to the latest version.

• New option --shorterthan to select families with a duration shorter than a
  given value. For this option and for --longerthan it is now possible to
  specify the duration in seconds, minutes, hours, or months, in addition to
  days and years.
• New option --colorby for many plot commands, to color families by a
  specific attribute other than the family number
• New option --colormap for many plot commands, to select a colormap
  for coloring families. If not specified, a default colormap for each
  attribute specified in --colorby is used.
• New option --range to manually specify the range of values for the color
  scale
• New option --force for commands that write files, to overwrite existing
  files without asking
• New option --freq_band for trace plotting commands, to override the
  frequency band specified in the config file
• New option --detailed for print_families, to print more detailed
  information about each family, including the list of events
• New option --output to save plots to files instead of showing them on
  screen
• Config option waveform_data_path renamed to sds_data_path
• New config option event_data_path to specify the path to a local directory
  with waveform files organized per event
• Add missing street map style for map_families
• Catalog scan: when more than a station is provided and the closest station
  to the event is not available, use the next closest station instead.
• Catalog scan: accurate estimation of the number of event pairs to process
• Initial support for plotting families found with template scan
• Improved reading of CSV catalog files:
  • avoid duplicated column guessing
  • ensure that prefectly matching column field names are correctly guessed
  • warn if an invalid time format is found
• Colored terminal output for warnings and errors

Release v0.6

Note: you might want to run requake update_config to update your config file
to the latest version.

• Verb plot_slip renamed to plot_cumulative. This new verb has new options
  to plot cumulative slip, cumulative moment, and cumulative number of events,
  and to make the plot logarithmic.
• New verb print_catalog: print the event catalog to screen
• New verb print_pairs: print the event pairs to screen
• print_families: also print minimum and maximum family magnitudes
• Additional models to convert magnitude to slip. Currently supported models
  are: Nadeau and Johnson (1998), Beeler et al. (2001), Eshelby (1957).
  Model selection is done using the mag_to_slip_model config parameter.
• New verb update_config: update an existing config file to the latest
  version

Release v0.5

• New config options: station_metadata_path and waveform_data_path to
  read station metadata and waveform data from files. Supports any metadata
  format supported by ObsPy and SDS (SeisComp Data Structure) waveform
  archives.
• Filter catalog files on reading using the criteria in the config file
• Improved time axes in plot_timespans and plot_slip for short time
  intervals
• print_families: autoset duration units based on the average duration
• plot_timespans: default sorting changed to family_number

Release v0.4.1

• Bugfix: requake executable was not installed

Full Changelog: v0.4.1...v0.4.1

Release v0.4

• Package license changed to GPL-3.0 or later
• New verb: read_catalog: read a catalog from web services or from a file
  (FDSN text, QuakeML, or CSV)
• New verb: scan_templates: scan a continuous waveform stream using one
  or more templates. Templates can be from families or from file
• New verb: print_families: print families to screen
• New verb: plot_slip: plot cumulative slip for one or more families
• New config parameter: clustering_algorithm to select the algorithm
  for building event families. Currently supported options are shared and
  UPGMA (default: shared)
• family_numbers argument is no more mandatory (default: all)
  • argument added to map_families and plot_timespans
• Config parameter trace_average_from_normalized_traces renamed to
  normalize_traces_before_averaging
• plot_timespans: possibility to sort by family_number
• New options for map_families to select a map style and a zoom level for the
  map tiles
• New option --minevents (-m) for many verbs, to select families with a
  minimum number of events
• Support for events with no location
• Bugfix: plot_timespans: correctly plot x time axis when sort by time

Release v0.3

• New verb: build_templates
• New option: cc_allow_negative to search for anticorrelated events
• New progressbar, using tqdm
• plot_families:
  • show average trace
  • pan/zoom traces using arrows
  • show/hide theoretical arrivals using 'a' (command line option removed)
  • show event origin time as y-label
  • show trace mean CC
  • also shift theoretical arrivals when aligning traces
• Bugfix: last family was not read from family file

Release v0.2

Mostly a bugfix release with a slightly improved trace plotting.

• Bugfix: scan_catalog could not run properly due to missing variable
• Bugfix: detrend traces before filtering
• plot_families: print number of events and station-event distance
