I created an "Errata" label for GitHub issues in the tosca-specs issue that can be use to track issues that need to be corrected in a future version of the spec. Feel free to comb through the existing issues in that repository and label those that you believe need consideration, or add additional issues as well. I plan to schedule a number of TOSCA Language meetings at the end of the summer to start discussing such issues with the goal of developing an update to the TOSCA v2.0 spec.
Thanks,
Chris
