The same information is also in
/usr/share/doc/exim4-daemon-heavy/NEWS.Debian.gz, both binaries are
built from the same source. Most Debian systems are configured to show
this information prominently on package upgrade, and it is also a good
idea to look in the package docs and the BTS before asking a search
engine.

Most information one finds on a search engine is outdated and maybe even
wrong. And the current information regading brand new software is often
not indexed yet.

This will only work as a temporary measure and will be removed in the
future. You should work on getting your configuration to work with the
tightened security features newer exims come.

If that are issues with Debian's default configuration please file bugs
so that we can fix them, if it's issues with your local configuration
you're on your own with that.
