                 Changes in version 2.0.0 (2021-01-10)                  

  - knownOrig database has been expanded and reformatted
  - New data objects document different calibration standards used to
    generate known-origin H and O isotope data
  - subOrigData supports transformation of data among different
    calibration standard scales using the 'standard-chain' method of
    Magozzi et al. (in press); format of return object from this
    function has changed
  - calRaster changes including new format for input object "known" and
    use of weighted least squares regression; tissue isoscape variance
    calculation updated to a + b - c, where a is isoscape grid cell
    variance, b is the residual variance of tissue predictions made from
    isoscape-tissue rescaling functions fit using values sampled from
    the isoscape with noise, and c is the variance of the sampled
    isoscape values
  - QA changes including new format for input object "known" and option
    to resample known data by site rather than by sample; for bySite
    option returned results are the average of site-level average
    statistics; argument order changed for consistency with calRaster
  - sp objects updated to support WKT2_2019 strings

                 Changes in version 1.2.1 (2020-06-03)
