# NES CHANGELOG

### 1.1.1
* Release date: 2023/04/12
* Changes and new features:
  * Sum of Nes objects ([#48](https://earth.bsc.es/gitlab/es/NES/-/issues/48))
  * Write 2D string data to save variables from shapefiles after doing a spatial join ([#49](https://earth.bsc.es/gitlab/es/NES/-/issues/49))
  * Horizontal Interpolation Conservative: Improvement on memory usage when calculating the weight matrix ([#54](https://earth.bsc.es/gitlab/es/NES/-/issues/54))
  * Improved time on **concatenate_netcdfs** function ([#55](https://earth.bsc.es/gitlab/es/NES/-/issues/55))
  * Write by time step to avoid memory issues ([#57](https://earth.bsc.es/gitlab/es/NES/-/issues/57))
  * Flux conservative horizontal interpolation ([#60](https://earth.bsc.es/gitlab/es/NES/-/issues/60))
  * Bugs fixing:
    * Bug on `cell_methods` serial write ([#53](https://earth.bsc.es/gitlab/es/NES/-/issues/53))
    * Bug on avoid_first_hours that where not filtered after read the dimensions ([#59](https://earth.bsc.es/gitlab/es/NES/-/issues/59))
    * Bug while reading masked data.
    * grid_mapping NetCDF variable as integer instead of character.

### 1.1.0
* Release date: 2023/03/02
* Changes and new features:
  * Improve Lat-Lon to Cartesian coordinates method (used in Providentia).
  * Horizontal interpolation: Conservative
  * 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.
  * Function get_spatial_bounds_mesh_format() to get the lon-lat boundaries in a mesh format (used in pcolormesh).
  * 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.
    * Correct read and write parallel limits.
    * Correct data type in the parallelization of points datasets.
    * Correct error that appear when trying to select coordinates and write the file.
