In this release, we implemented a new permission – Ignore the limit if already posted in the thread. When authorization is enabled, users will be able to post an answer in a thread without further restriction if they already have a message in this thread.
The authorization is by group of users and by nodes. It can be customized for a full user group or for specific nodes only. By default, it is disabled and the behavior of the product is identical to that of version 2.0.x.
