We will upload the correct versions for 3.10.1 with unit processes today or next week latest. We directly applied the corrections from ecoinvent to our latest Nexus versions 3.10, so that the database integrations into openLCA will remain exactly the same and only some few exchange values are updated according to 3.10.1.

Please be aware that the changes from version 3.10 to 3.10.1 are very small. The first corrections by ecoinvent are some elementary emissions flows in "coke production" and "coke production, wet quenching" in RoW and CN, which does slightly affect some toxicity indicators and no other impact categories will change. You will find the file with these changes by ecoinvent here:  Correction Coke 3.10 All System Models

Additionally, there was a wrong market share for Brazil inside the market group for electricity in RLA (Latin America and the Caribbean). The 1-page change report is here: Report of Changes

The issues were already known for some time and that's why it was surprising that the 3.10.1 update was only released together with the upcoming 3.11. In case you still have a valid Nexus/ecoinvent license, you can directly use the upcoming ecoinvent 3.11 which will have major updates and there is no need to use 3.10.1 in this case. 

We cannot tell the exact release date for version 3.11 in openLCA, but similar to last year it will be only a few weeks after the release by ecoinvent.

Thanks, I will try to work with the unit-process version in next projects and let you know about the experience.  At the moment I can say that the calculation requires more time and memory, probably because much more detailed results are produced. But I will test and use your hints.

Anyway, the system version is part of the package, so I would appreciate a feedback about when it will be availble for ecoinvent 3.10.1. Many thanks.
