**auto-SNES**:
  * Oriol is **testing the conservative** remapping with auto-SNES & AS/4.
  * Dani Beltran suggest to remove the current AS/4 to point to the new tag, but I rejected the idea until auto-SNES is adapted to the new tag changes. [[https://earth.bsc.es/gitlab/es/autosubmit/-/issues/1022|Autosubmit #1022]]

**NES**
  * v1.1.0 release done:
    * Improve Lat-Lon to Cartesian coordinates method (used in Providentia).
    * Horizontal Interpolation: Conservative

      * 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.

      * Correct the way we retrieve the level positive value.

      * Correct how to calculate the spatial bounds for all grids: use read axis limits instead of write axis limits.
      * Calculate centroids from coordinates in creating shapefiles, instead of using the geopandas function 'centroid', which 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 errors that appear when trying to select coordinates and write the file.
