Update to 5.0.7:

5.0.7
This is version 5.0.7 of the shell.  This is a stable release.
There are minor new features as well as bug fixes since 5.0.6.

Note in particular there is a security fix to disallow evaluation
of the initial values of integer variables imported from the
environment (they are instead treated as literal numbers).  That
could allow local privilege escalation, under some specific and
atypical conditions where zsh is being invoked in privilege elevation
contexts when the environment has not been properly sanitized, such
as when zsh is invoked by sudo on systems where "env_reset" has
been disabled.

5.0.6
This is version 5.0.6 of the shell. This is a stable release.
There are minor new features as well as bug fixes since 5.0.5.
