Security issues fixed:
- CVE-2018-1100: Fixes a buffer overflow in utils.c:checkmailpath() that
 can lead to local arbitrary code execution (bsc#1089030)
- CVE-2018-1071: Fixed a stack-based buffer overflow in exec.c:hashcmd()
 (bsc#1084656)
- CVE-2018-1083: Fixed a stack-based buffer overflow in
 gen_matches_files() at compctl.c (bsc#1087026)
Non-security issues fixed:
- The effect of the NO_INTERACTIVE_COMMENTS option extends into $(...) and
 `...` command substitutions when used on the command line.
- The 'exec' and 'command' precommand modifiers, and options to them, are
 now parsed after parameter expansion.
- Functions executed by ZLE widgets no longer have their standard input
 closed, but redirected from /dev/null instead.
- There is an option WARN_NESTED_VAR, a companion to the existing
 WARN_CREATE_GLOBAL that causes a warning if a function updates a
 variable from an enclosing scope without using typeset -g.
- zmodload now has an option -s to be silent on a failure to find a module
 but still print other errors.");
