Hello,

actually it is starting with v3.2.0. But it is not visible in the 
script, like the other operations performed on the headers -- they 
operations are kept as a diff (patch) list, not applied immediately.

So, you will see the new From header when the message is sent to the 
network, before that is the original value. You can use 
msg_apply_changes() to make the changes visible immediately.

Cheers,
Daniel
