* Add check to make sure not all arrays are empty during matrix construction * Allow numpy loading pickled data
1.7.7
Switch `lca.demand` when running `.redo_lci` or `.redo_lcia`. Thanks Aleksandra Kim!
1.7.6
Fixed [25](https://bitbucket.org/cmutel/brightway2-calc/issues/25/function-load_arrays-in-utilspy-unsorted): Sort array filepaths when loading. Thanks Pedro Anchieta!
1.7.5
Merged [Pull Request 4](https://bitbucket.org/cmutel/brightway2-calc/pull-requests/4/numpy-array-passthrough/diff) to directly pass Numpy or byte arrays instead of filepaths. Thanks Jan Machacek!
1.7.4
* Improved support for independent LCA calculations (i.e. without Brightway2 databases, only processed arrays) * Added ability to calculate LCAs in a single matrix (for BONSAI)
1.7.3
Updated Monte Carlo for upstream presamples changes
