openLCA has been largely refactored in the last half year or so to allow working with huge databases such as ecoinvent 3 or the Social Hot Spots Database. We also added several usability improvements and new features, e.g. a much more refined parameter management. The current release is still beta, some features of the 1.3.x development path are still being implemented, but you are of course invited to have a look. To install, just extract the archive and double-click on openLCA.exe. A tutorial is available at the documentation and download section, a performance comparison will be released soon. openLCA 1.4 beta is available at the download section.
