[exim] Exim 4.84_2 #1 : WARNING: purging the environment.

Hi,

Exim 4.84_2 #1 built 24-Mar-2016 16:26:05 :

My MTAs on Centos 6 were updated a few days ago and now Logwatch is
inundated with

" WARNING: purging the environment.
Suggested action: use keep_environment and add_environment. "

Please may I ask what 'Environment' ?
and why was it necessary to introduce this strangeness ?

Before the update Exim was working fine.
