finding the code and upgrade notes

[Boylan, Ross]

It would be good if the COPYRIGHT had a pointer to the Debian source code.

It would be nice if the code were browseable online.  https://tracker.debian.org/pkg/cyrus-imapd-2.4 does have a browse link for the VCS, but clicking on it only gives you a directory with 2 icons.

I was looking for this because I was looking for upgrade notes and hoping they were in the source.  Is that where to look for them?

Thanks.
