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.
