The question is about permission for newly added custom field in a managed package. Consider the situation when we have a managed package (say version 1.0), and we're going to Push upgrade on customer's Org (to version 2.0 which contain new custom field). What will be field level security setting for this new custom field? When we install package first time Salesforce prompts us about security settings for all the profiles. But how are they set during Push upgrade?
