Folks, I would like to see this merged today -- fixes a regression in reStructuredText header levels introduced in 2.2.0 vs. the original Zope2 reStructuredText wrapper:
https://github.com/plone/Products.PortalTransforms/pull/15
Without this fix, multiple Products.Archetypes BaseUnit tests fail in both 5.0.x and 5.1.x buildout.coredev.
This pull request is 20 days old, and checks pass -- if there are no takers to review, I will merge it myself tomorrow.
