Version 2.6.3

• Release numpy version pin, add xlrd version pin
• Fix excel import with multiple databases
• Add Tree-view for IC methods (thanks @marc-vdm!)
• Add app version to help menu

Version 2.6.2

• Improve the database relink dialog to allow multiple databases to be relinked at once.
• Various bugfixes.
• Rework parameter deletion to be more aggressive, this includes: deleting parameters for activities that no longer exist.

Version 2.6.1

• Add an option for importing databases (and parameters!) through excel. Note that this uses the brightway2 excel formatting for the data.
• Streamlined the database import wizard.
• Fix a bug where missing activity parameters would the entire parameter system to lock up.

Version 2.6.0

• Adds an implementation of Global Sensitivity Analysis to the Activity Browser!
• Adds tools for a simplified way of testing different process flow scenarios.
• Minor fixes and UI improvements.

For all changes see the changelog.

Version 2.5.1

• A number of bug-fixes and improvements with regards to editing uncertainty.

• Fix a memory leak issue when using the Forwast database.

• Improve Monte Carlo sampling by adding parameter sampling and allowing fine-grained control over which uncertainties are sampled.

• Allow python3.8 to be used.

Version 2.5.0

• Adds scenario analysis to the Activity Browser!

• A number of fixes and code improvements were made that should make it easier for users to make use of parameters and improve usability of aggregation

• This release also marks the switch from PyQt5 to PySide2.

Please see the changelog for a complete list of changes.

Version 2.4.0

Introducing parameterization to the Activity Browser!

This version allows users to create and manage brightway2 parameters in the new Parameters tab. With these parameters it is now possible to craft formulas for activity exchanges, allowing users to quickly put together a parameterized system.

This release also contains the following:

• The database importer now gracefully handles a failed ecoinvent import, and in addition:
  • There is a small biosphere3 updater tool which uses brightway2-io data to add missing flows.
• Checkboxes are back and hopefully here to stay.
• Various code improvements and bugfixes.

Version 2.3.4

Likely the last stable version before the introduction of parameterization in 2.4.

This version includes a number of fixes related to the refactoring of tables that occurred in version 2.3.3.
Additionally, a number of small but annoying development-related frustrations are now handled.

Notable inclusions:

• (MacOS) Databases table broken checkboxes (caused by refactoring in 2.3.3) are now simple true/false values, with a small explanation on how to alter the value. Checkboxes will be coming back in the future once the correct Qt fix is found.
• Downloading ecoinvent through the importing mechanic will now correctly link the 'type' the database available to the ecoinvent version.
• Tests can now be performed on the latest versions of pytest. Automated testing now covers python 3.6 and 3.7 on windows, linux and mac.

Version 2.3.3

This version includes refactoring for almost all of the tables: Any classes inheriting from QTableWidget were converted to make use of QTableView instead. Apart from unifying the code to make future work easier, this also fixes an issue with sorting tables.

Other fixes include:

• A workaround for the application breaking when an LCA is run on data without uncertainty information.
• Updating the metadata when editing activities now functions correctly.
• Databases being removed after a dialog where the user selected No (as in, no I don't want to remove the database).

Version 2.3.2

Includes a number of bug-fixes for deleting databases and removing deleted projects on windows machines.

Also adds simple aggregation for EF and Process contribution data.
