On 2/5/21 in this email list Carsten Dominik suggested removing the key binding C-c <SPC> for "org-table-blank-field". That got implemented for Org-9.5, but the Info file didn't get changed, so it still says:
‘C-c <SPC>’ (‘org-table-blank-field’)
Blank the field at point.
in node (org) Built-in Table Editor
In my own usage of tables I use this key binding a lot, so I am going to figure how to restore it.
I don't subscribe to this list, because it's too overwhelming.
