We are happy to announce the release of our newest version: openLCA 1.10.3!

Version 1.10.3 comes with some minor bug fixes that are mainly relevant for users of the newly implemented flow mapping tool as well as the connection to the openLCA Collaboration Server.

The updates in the prior version 1.10.2 included a notable number of improvements and bug fixes which ensure that openLCA also runs properly on Linux and macOS. More technically-oriented users can learn more by reading about these improvements on the openLCA GitHub page.

A fast network calculation is added for processes, which allows calculating networks without making a product system first. This saves time and memory for densely populated databases with many connections, tpyically I/O databases, and makes e.g. the PSILCA developer database fully calculable also on an average computer. Note that this works only if the database contains unambigous, simple links, which can be checked before using this feature.

Also new, the ‘general information’ tab of a process now shows images provided these are contained in the datasests. These images – for example flowcharts – support the information given in the process description and were previously linked in the ‘modeling and validation’ tab. Additionally, the map view in the results tab has been further enhanced.

Furthermore, openLCA now includes an experimental flow mapping tool. With its help, it is possible to create flow mappings for imports and replacements of flows in a database. The development of different features of this tool was supported by DLR, FZJ and US EPA.

Feedback from our community is always appreciated.

How to get the latest version?

The most recent version of openLCA is always available at the openLCA Downloads website. You can use either the installer (your will need to de-install your older version) or the .exe file included in the zip file also provided in the downloads page (no need to de-install your older version). In both cases, when you open a database you will be asked to update it to the new database format. By clicking OK, you accept the conversion. The content of the database will not be affected, only the structure. Have in mind that this process cannot be reversed. Once your database has the new database structure it cannot be opened with earlier openLCA versions.
