# meteoland 2.0.1
- Hard deprecation of "sp", "raster" and "rgdal" depedencies, including functions and classes using
  them.
- Removed old vignettes and old example data
- meteospain dependency moved to SUGGESTS

# meteoland 2.0.0
- Added the new workflows to work without `sp`, `raster`, `rgdal` packages.
**This is a breaking change**, meaning it affects all the package:
  - New functions for interpolation, calibration, cross-validation and
    summarising workflows has been added. See
    `vignette("tidy-meteoland", package = "meteoland")` for more info.
  - Added deprecation notices for all functions that use `sp`, `raster`, `rgdal`
    packages internally.
  - All functions using `sp`, `raster`, `rgdal` packages enter in *maintenance*
    mode. Starting in June, they will stop working in newer versions of
    `meteoland`, as these packages also enter in *maintenance* mode
  - Added tests for new workflows
  - Added tests for results equivalences between new and current workflows
