How to notify all members on any updates to zoho crm?

Hi,

I am using the free version of zoho CRM and currently seeing this will work for our company. We are a small company and wanted to be more informed about all the changes in zoho.  

1. How do I s et notifications that go to the team for any and all changes made in Zoho. At this point, we'd rather be over-informed than under-informed.
2.  Create a custom field (or rename an unused field) to be able to capture any "Product Feature Requests" from customers or prospects we're talking to.

I have anyone can point me in the right direction that would be great. I'm just not sure which area would help complete these settings. Automation vs. rules vs. feeds etc...

Thanks
