Uncompatible changes:
This release of Exim includes one incompatible fix: the behavior of
expansion of arguments to math comparison functions (<, <=, =, =>, >)
was unexpected, expanding the values twice. This fix also addresses a
security advisory, CVE-2014-2972. This is not a remote exploit, but if
content that is searched by the above math comparison functions is under
the control of an attacker, specially crafted data can be inserted that
will cause the Exim mail server to perform various file-system functions
as the exim user.
