Bugfixes - 21.6.1

• Harden the fish activator prompt against user functions that shadow builtins. Routing functions, printf, string, echo and source/. through builtin stops a shadowing function (such as a dot-style directory navigator that redefines .) from hijacking the prompt and dropping the previous command's exit status, matching the CPython fix in [gh-140006](https://github.com/pypa/virtualenv/issues/140006) <https://github.com/python/cpython/issues/140006>_.

Bugfixes - 21.5.1

• Refuse to create environments whose Python the bundled wheels no longer cover (currently below 3.9). virtualenv used to substitute the newest bundled pip, which cannot run on such a target, leaving a broken environment; seeder selection now rejects it up front with a clear error. --no-seed and third-party seeders that ship compatible wheels still work - by :user:gaborbernat. (:issue:3171)
