Exchange rate

Hi to all,
I am experiencing Manager (desktop edition) and using multi-currencies. I have the following questions:

How and where can I know if I am using the latest version?
Where can I find the exchange rate screen management in settings?
Where can I find a full and explicit userguide?

Thank you for helping.

Thank you. Just found how to do for exchange rate screen.
need to know for version and userguide.

This is generally not that important. Manager advances at an extremely rapid pace, often with multiple releases per day. But these tend to be behind-the-scenes improvements. Major functional changes are announced in the Releases category on this forum.

See the Guides:

Thank you for your help.
