Workflow query customer


We have releases which go live as per sprint. Authors do content work. Publishers publish them on a given time.

Is there a way for a site admin to find the number of content created for a release.

Also what is the lock model in brx. Can u editors work on same file?

While deploying a page I want all the dependancy to deploy. Not before that. If I changed an image and updated a page. The image should deploy when the page is published.
