BREAKING CHANGE: some aliases have been renamed to be consistent with the rest.
Mainly, aliases for `juju show-` commands are renamed to `jsh*`. This also means
that `jsh` and `jshc` have been renamed to `jssh` and `jsshc`. Have a look at the
README for the complete alias changes.

BREAKING CHANGE: `wjst` will no longer show storage in the status
output. This is done for consistency with the `jst` and `jsts`
aliases.

BREAKING CHANGE: the `zsh_reload` was deprecated long ago and showed
a deprecation message. The `src` function was replaced by the CLI
command `omz reload`, so use that instead from now on.

BREAKING CHANGE: the `django` plugin was deprecated in 2021-09-22. With
this change it has now been removed altogether. Zsh already provides
built-in completion for Django commands.

BREAKING CHANGE: the `npx` plugin used a feature of `npx` to check for
npm packages and run them if a command was not found. This feature was
removed in v7.0.0 and was deemed insecure. The `npx` plugin is now
officially deprecated and will be removed soon.

When generating completions for Cargo, if the Rust sysroot
(i.e. `rustc +${${(z)$(rustup default)}[1]} --print sysroot`) contains
spaces, Cargo completions will not work because the spaces are not
escaped, thus passing two arguments to the "source" command instead of
one. The spaces need to be escaped for this to work.
