thank you, very much, Eric! I'm sure Plone 5.2 will be one of the most crucial releases in many time.
it's really important that everybody work on making third party add-ons available; the future of Plone depends in part on a healthy add-on environment.
we need to push support for Plone 5 and Python 3 now.
do we have any pointers on how to update our code?
