Changes in version 0.5.0 (2026-04-01)                  

New features

This release provides new functionality with regard to ionic ratios and
plotting them in a Van Wirdum diagram (#114):

  - New function calculate_ir() to compute the ionic ratio.
  - New function ggplot_vanwirdum_background() to get a Van Wirdum
    diagram as ggplot object (without custom data), to which data layers
    can be added by the user.
  - New vignette on plotting chemistry data:
    vignette("v230_chem_plots").

Improvements and fixes

  - get_locs() now substitutes filterlength values of 0 m by 0.3 m
    (#108). Before, this was only done for missing filterlengths.
  - Harden get_chem() with regard to the iron / conductivity ratio
    calculation (used by the en_fecond_threshold argument) (#122):
      - Limit the calculation to the requested locations.
      - Set as missing if conductivity is set as zero in the data
        warehouse, and present a warning in case this occurs.
  - Apply tidyverse code style (#119).
  - Various maintenance.

                 Changes in version 0.4.2 (2023-09-15)                  

  - Move package {KSgeneral} to Suggests (#103). This avoids package
    breaking when {KSgeneral} is not available on CRAN. For the moment
    not taking further measures to protect against it, as the package is
    currently back on CRAN.

                 Changes in version 0.4.1 (2021-06-11)                  

  - Fixed non-working get_xg3() and get_chem() for data frame input, by
    avoiding the currently defunct dbplyr::db_drop_table() (#89,
    08bc66d).
  - Various maintenance (#81, #86, #87, #88, c382499).

                 Changes in version 0.4.0 (2021-01-18)                  

  - This release has been made compatible with dbplyr 2.0.0 (on CRAN);
    the dbplyr fork is not needed anymore (e66e58f, #74).
      - Follow the installation procedure on the homepage (readme) to
        upgrade.
      - Lazy results of get_locs(), get_xg3() and get_chem() are not
        sorted anymore. Sorting is done in tibbles only, i.e. if collect
        = TRUE. For more information, consult the Note added in the
        documentation of these functions.
  - Fix broken selectlocs_xg3() and selectlocs_chem() (#73).
  - Fix get_locs() error when no locations remain after spatial masking
    (c96421e).
  - Fix get_locs() error when obswell_aggr = "mean" (#80).
  - Adopt further inbodb functionality (#75):
      - re-export its dbDisconnect();
      - transfer handling of character encoding to inbodb.
  - Improve documentation and pkgdown website (#76, #77, 3986b4e).

                 Changes in version 0.3.0 (2020-05-20)                  

New features

  - New function cluster_locs() to spatially cluster locations (well
    clusters) (#39)
  - More fun with get_locs():
      - optionally allow groundwater piezometers with missing
        filterdepth (argument filterdepth_na)
      - optionally replace missing filterdepth values in a conservative
        way, based on tubelength (argument filterdepth_guess, #44)
      - return eight more observation well attributes beside filterdepth
        (#44)
      - four methods are available to aggregate observation well
        attributes per location (argument obswell_aggr, #44)
      - applying a spatial mask is now a little speedier (#57)
  - as_points() and get_locs() return a warning when duplicated
    coordinates occur in their local result (#51, thanks @w-jan)
  - Package dependency moved from inborutils to inbodb: this is a change
    within connect_watina() which should not affect its behaviour and
    which reduces overall package dependencies.

Further, a number of smaller fixes and enhancements were made.

                 Changes in version 0.2.6 (2020-02-28)                  

  - Redo fix get_locs(): calculation of soilsurf_ost (#43)

                 Changes in version 0.2.5 (2020-02-27)                  

  - Bugfix in get_locs(): calculation of soilsurf_ost (#42)

                 Changes in version 0.2.4 (2020-01-29)                  

  - Bugfix in convertdf_enc() (#34)
  - Some small documentation improvements

                 Changes in version 0.2.3 (2020-01-09)                  

  - Documentation is now generated by the newer roxygen2 version 7.0.2,
    resulting in a better layout of function arguments in the 'usage'
    section.

                 Changes in version 0.2.2 (2019-11-04)                  

  - On Windows, the functions now convert 'weird' characters from the
    data warehouse to proper UTF-8.
  - Bugfix (#29) in get_locs() regarding the default implementation of
    the loc_validity argument.

                 Changes in version 0.2.1 (2019-10-14)                  

  - Fixed bug in some hyperlinks in function documentation, affecting
    the installation process on Windows (warnings were thrown).

                 Changes in version 0.2.0 (2019-10-02)                  

New features

  - Several functions have been added to query and process chemical
    data.
  - Three vignettes have been added.
  - Improved various existing functionalities from version 0.1.0, based
    on user's feedback.
