Changes in version 2.1.0                        

  - Added separate columns for Turbidity in NTU or FNU
  - Updated all datasets
  - Added Salvage
  - Corrected SKT data to fix negative tow volumes, and adding a test to
    ensure that doesn't happen again.
  - Add exported function to wrangle and save the integrated dataset for
    EDI publication: data_integrate

                        Changes in version 2.0.0                        

  - Set Count values to 0 for all cases of "No fish caught"
  - Standardized usage of Length_NA_flag
  - Added SKT, SLS, STN, 20mm, DJFMP, and EDSM datasets.
  - Fixed issues with incorrect incorporation of zeroes in the zero_fill
    function.
  - Updated FMWT, Bay Study, and Suisun data.

                        Changes in version 1.0.0                        

  - Fixed incorrect Bay Study Tow_area values by converting Nautical
    miles to meters.
  - Updated FMWT coordinates to latest version from CDFW. Prior version
    may have had some 700 stations far east from their actual locations.
  - Fixed issue with Suisun data by forcing all counts corresponding to
    OrganismCode=="NOCATCH" to be 0.
  - Tweaked zero_fill to remove rows with Taxa==NA.
  - Re-added Survey variable to FMWT and Baystudy datasets.

                        Changes in version 0.6.0                        

  - Removed life stage from the "Taxa" column.
  - Added option to zero_fill to filter to specified species, along with
    more tests to ensure there are zeros to fill.

                        Changes in version 0.5.0                        

  - In Suisun data, added counts with no corresponding length
    measurements, e.g., fish within a certain size group were counted
    and not measured and no fish within that size group were measured.
    Despite the use of the word "fish" the vast majority of these
    instances are for invertebrates. Only 334 rows out of 24,289
    corresponded to fish.
  - Documented data processing code.
  - Fixed some incorrect station locations

                        Changes in version 0.4.0                        

  - Added new function zero_fill to fill in 0s for species not recorded
    in a sample and deal with the unknown lengths from the Suisun data.
  - Added new argument size_cutoff to remove fish below a certain
    length.

                        Changes in version 0.3.0                        

  - Added a NEWS.md file to track changes to the package
  - Added length conversions to convert Suisun measurements to Fork
    length or Total length for species with no fork
  - Added tests
  - Re-ordered columns of internal datasets to a logical order
  - Removed invalid tows from Baystudy data
