Replace bw2speedups indexing with numpy array trickiness which is ~5 times faster

1.5.4 (2017-02-24)#

Remove non-ascii characters from license text, because setuptools

1.5.3 (2016-10-28)#

Restructure imports to not depend on bw2data

Bugfix for broken import statement

1.5 (2016-09-15)#

Merge pull request from Adrian Haas to enable Pardiso solver usage when available.

1.4 (2016-07-14)#

Added utility functions for load_calculation_package and save_calculation_package for independent LCAs and cloud computing.
Compatibility with bw2data 2.3

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.

1.3.3 (2016-06-10)#

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. ParameterVectorLCA.next() 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).

1.3.1 (2016-06-06)#

CHANGE:Updates for bw2data 2.2
BUGFIX: Correctly handle regionalized CFs in site-generic calculations
FEATURE: Add contribution methods to LCA classes

1.3 (2016-05-28)#

BUGFIX: Correctly handle project names in multiprocess calculations

1.2.1 (2016-03-14)#

BUGFIX: switch_* was seriously broken due to new handling of processed arrays filepaths

1.2 (2016-03-14)#

Feature: Py3 compatibility
FEATURE: Independent LCAs which don’t rely on bw2data and the brightway2 ecosystem
Feature: Add DenseLCA
FEATURE: Added switch_* and to_dataframe methods to LCA class
FEATURE: Allow graph traversal to skip links in static databases
BUGFIX: Terminate multiprocessing pools after calculations
CHANGE: Load data automatically in Monte Carlo
CHANGE: Automatically clean dirty databases before starting calculations

Plus lots of small bugfixes, and compatibility with projects.

1.0 (2015-03-08)#

CHANGE: Split activities and products

0.17.1 (2015-02-13)#

BUGFIX: Don’t require substitution in TYPE_DICTIONARY.

0.17 (2015-02-13)#

FEATURE: Properly handle substitution type exchanges
CHANGE: Compatible with bw2data version 2
BUGFIX: Fix handling of nested dependent databases

0.16.1 (2014-12-05)#

CHANGE: Better documentation for most code.
BUGFIX: Graph traversal handles most coproducts, and raises sensible errors when it can’t.

0.16 (2014-08-03)#

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.

0.13 (2014-04-16)#

BREAKING CHANGE: LCA.fix_dictionaries now sets/uses _mapped_dict to determine if fix_dictionaries has been called.
BUGFIX: LCA.build_demand_array doesn’t break if fix_dictionaries has been called.

0.12 (2014-02-13)#

BREAKING CHANGE: Matrix builder will only include parameter array rows that are correctly mapped, instead of raising an error when unmapped rows occur. This behaviour can be turned off by passing drop_missing=False.

0.11.1 (2014-01-29)#

BUGFIX: Change column names in method matrix building to be consistent with bw2data 0.11

0.11 (2014-01-26)#

BREAKING CHANGE: Graph traversal was reworked, and some functionality for interpreting the output was moved to bw2analyzer.
BREAKING CHANGE: Deleted SimpleRegionalizedLCA class. Regionalization will be provided in bw2regional.
BREAKING CHANGE: Deleted initial sensitivity work, moved for now to branch, as it was not yet usable.
FEATURE: Much better and more thorough documentation.
FEATURE: Improved testing and test coverage
