Changes in version 1.2-0 (2024-08-19)                  

  - add gsw_infunnel()
  - switch from Calloc to R_Calloc etc, so package builds with "strict"
    header checking (issue #63).

                 Changes in version 1.1-1 (2022-10-16)                  

  - Remove a journal link that fails because of an invalid certificate.
  - Fix a C function declaration that is invalid for some compilers.

                        Changes in version 1.1-0                        

This update is based on C code from https://github.com/TEOS-10/GSW-C
(release v3.06-16-0, commit 657216dd4f5ea079b5f0e021a4163e2d26893371)
and the .mat data file from https://github.com/TEOS-10/GSW-Matlab
(commit 38c9635d6fd93e74c2648e4ee23cec49c1f58530). It was necessary to
make some changes to the within-documentation test suite, as listed
below; MRD stands for Mean Relative Difference from the values in the
previous CRAN release of gsw, version 1.0-6 released 2021-07-07.

  - gsw_rho_second_derivatives()$rho_SA_p: MRD 0.4
  - gsw_rho_second_derivatives_wrt_enthalpy()$rho_SA_SA: MRD 1e-3
  - gsw_specvol_second_derivatives()$specvol_SA_p: MRD 0.2
  - gsw_specvol_second_derivatives_wrt_enthalpy()$specvol_SA_SA:
    MRD 3e-4
  - gsw_thermobaric()$rb: MRD 0.04

                        Changes in version 1.0-7                        

  - Update to GSW-C as of 2021-07-14, github commit
    bad2c9e4e154597ce563aaaf3ce09b1c52a2ab46. This does not change any
    existing functions in GSW-R.
  - Add gsw_SP_salinometer().
  - Add gsw_o2sol().
  - Add gsw_o2sol_SP_pt().

                 Changes in version 1.0-6 (2021-07-07)                  

  - Update to GSW-C as of 2021-07-06, github commit
    9c10670e89fce906da2cebce3399d73c054e769e.
  - Remove dependency on the 'testthat' package.
  - gsw_z_from_p() and gsw_p_from_z() gain parameters
    geo_strf_dyn_height and sea_surface_geopotential.
  - Relax gsw_geo_strf_dyn_height() test, since values are tied to a new
    Matlab interpolation scheme that is not incorporated in GSW-C.

                 Changes in version 1.0-5 (2017-08-09)                  

  - Update to GSW-C 3.05-4.
  - Make internal sort routines be machine-independent.

                 Changes in version 1.0-4 (2017-08-02)                  

  - Update to GSW-C 3.05-3.
  - Handle NaN values better.
  - Add dozens of new GSW functions.

                 Changes in version 1.0-3 (2015-01-19)                  

  - First version, using GSW version 3.03.
