- update to 5.9:
  zsh 5.9 is dedicated to the memory of Sven Guckes, who was, amongst other
  things, a long-time zsh advocate.  For more information, see:

  When unsetting a hash element, the string enclosed in square brackets is
  interpreted literally after any normal command-line-argument expansions.
  Thus
    unset "hash[$key]"
  first expands $key as usual for a double-quoted string, and then interprets
  that result as the exact hash element to unset.  This differs from previous
  versions of the shell, which would also remove a leading backslash for an
  unusual subset of characters in the expansion of $key.  Note this also
  means, for example, that now
    unset 'hash[ab]cd]'
  unsets the element with key "ab]cd" rather than silently doing nothing.
  The function command learnt a -T option to declare a function and enable
  tracing for it simultaneously.
  The option SHORT_REPEAT was added to enable the short syntax of
  SHORT_LOOPS for the repeat command only. It is disabled by default.
  The _arguments function now supports NUL-delimiting optargs in the
  opt_args array via the -0 option. Developers of completion functions
  should find this easier to handle reliably than the default
  colon-delimiting behaviour.
  The zsh/system module's `zsystem flock` command learnt an -i option to
  set the wait interval used with -t. Additionally, -t now supports
  fractional seconds.
  The option CLOBBER_EMPTY was added to enable the overwrite behaviour
  of CLOBBER for empty files only. It is disabled by default.
  A (-) expansion flag was added. It works like (n) but correctly sorts

- update to 5.8.1 (bsc#1196435, CVE-2021-45444):
  * CVE-2021-45444: Some prompt expansion sequences, such as %F, support
    'arguments' which are themselves expanded in case they contain colour
    values, etc. This additional expansion would trigger PROMPT_SUBST
    evaluation, if enabled. This could be abused to execute code the user
    didn't expect. e.g., given a certain prompt configuration, an attacker
    could trick a user into executing arbitrary code by having them check
    out a Git branch with a specially crafted name.
    This is fixed in the shell itself by no longer performing PROMPT_SUBST
    evaluation on these prompt-expansion arguments.
    Users who are concerned about an exploit but unable to update their
    binaries may apply the partial work-around described in the file
    Etc/CVE-2021-45444-VCS_Info-workaround.patch included with the shell
    source. [ Reported by RyotaK <security@ryotak.me>. Additional thanks to
