1.3.6 (2016-07-01)#

Fixed bugs where RNG and technosphere matrix builder would change values in arrays meant to be static

1.3.5 (2016-07-01)#

Fix bugs and add tests for ParameterVectorLCA

1.3.4 (2016-06-10)#

Changed ParameterVectorLCA: Can no longer be called, split off rebuild_all into a separate method, added tests.

Better test coverage and Windows comaptibility

1.3.2 (2016-06-08)#

  • FEATURE: Add class and mixin for Monte Carlo using direct solvers

  • CHANGE: Move tests to root directory and add Monte Carlo tests

  • CHANGE: Consistent use of __next__ and next() so that all Monte Carlo iterator classes are Py2/3 compatible and programmed the same way. will no longer work on Python 3; instead, call next(ParameterVectorLCA). When providing a new vector, call the class itself (after it is instantiated): pv = ParameterVectorLCA(args); pv(new_vector).

FEATURE: Changes in MatrixBuilder should make normal static LCA calculations about three times faster.

0.15.1 (2014-07-30)#

Update dependencies.

0.15 (2014-06-11)#

BREAKING CHANGE: Use Database.filename for processed data. Requires update to bw2data version 0.16 or greater.
