Hi everyone,
We have added a CC field in the communication composer and added the ability to explicitly mention who should be notified.
If no CC is selected, then those who have starred the doc, those who have been assigned the doc and the owner of the transaction is notified.
The previous system to implicitly send email to all email addresses in any previous email in that document has been removed.
Here’s the pull request for your reference: https://github.com/frappe/frappe/pull/1307
