Didn't you find some release notes?
There should be explained why that change was necessary.
And, yes, a limited understanding of the term "environment" is
supposed.

Probably it's still working fine. But there is a small chance that
some parts do not work anymore as you'd expect it, because the may
depend on environment variables. And for security reasons Exim purges
all these variables now.
With
keep_environemnt =
you agree with the built-in default.

Again, there should be release notes and the spec file, giving some
explanation. Please feel free to give us hints on how to make it more
comprehensible.

Yes, sorry for that.
But we had to introduce that incompatible change. And you should upgrade
your version, for security reasons.
Or try some MACRO magic
.ifndef VERY_OLD_EXIM
keep_environment =
.endif
And for your old Exim you add -DVERY_OLD_EXIM to the command line.
