Changelog

v2.2.0

Highlights

ESMValCore is now using the recently released Iris 3. We acknowledge that this change may impact your work, as Iris 3 introduces several changes that are not backward-compatible, but we think that moving forward is the best decision for the tool in the long term.

This release is also the first one including support for downloading CMIP6 data using Synda and we have also started supporting Python 3.9. Give it a try!
