# NES CHANGELOG

### 1.1.0
* Release date: 2023/02/07
* Changes and new features:
  * Improve Lat-Lon to Cartesian coordinates method (used in Providentia).
  * Function to_shapefile() to create shapefiles from a NES object without losing data from the original grid and being able to select the time and level.
  * Function from_shapefile() to create a new grid with data from a shapefile after doing a spatial join.
  * Function create_shapefile() can now be used in parallel.
  * Function calculate_grid_area() to calculate the area of each cell in a grid.
  * Function calculate_geometry_area() to calculate the area of each cell given a set of geometries.
  * Bugs fixing:
    * Correct the dimensions of the resulting points datasets from any interpolation.
    * Amend the interpolation method to take into account the cases in which the distance among points equals zero.
    * Correct the way we retrieve the level positive value.
    * Correct how to calculate the spatial bounds of LCC and Mercator grids: the dimensions were flipped.
    * Correct how to calculate the spatial bounds for all grids: use read axis limits instead of write axis limits.
    * Calculate centroids from coordinates in the creation of shapefiles, instead of using the geopandas function 'centroid', that raises a warning for possible errors.
    * Enable selection of variables on the creation of shapefiles
