Brightway Versions and Compatibility#
Brightway2 vs. Brightway25#
Brightway 2.5 is the next generation of the Brightway2 framework for life cycle assessment. It provides new capabilities for cloud computing and model interaction, with the use of a new processed data library and a separation between the calculation library and a library for matrix construction and manipulation.
– from the Brightway 2.5 repository readme file
Brightway 2.5 is the next step on the way to the next version of Brightway, as detailed in the Brightway Strategic Development Plan. In practice, this means that the meta-packages brightway-lca/brightway2 and brightway-lca/brightway25 will install different versions of the Brightway packages. For instance:
package |
Brightway 2 version |

|
< 1.8.1 |
