4.7 (2021-11-10)

Bugfix

* Fix a bug since v4.6 where certain Unix system directories were incorrectly
  assumed to exist and resulted in
  a :class:`FileNotFoundError`. (:issue:`[#6331](https://github.com/pyinstaller/pyinstaller/issues/6331)`)
Hooks

* Update ``sphinx`` hook for compatibility with latest version (4.2.0).
  (:issue:`[#6330](https://github.com/pyinstaller/pyinstaller/issues/6330)`)
Bootloader

</code></pre>

<ul>

<li>(Windows) Explicitly set <code>NTDDI_VERSION=0x06010000</code> and

<code>_WIN32_WINNT=0x0601</code> when compiling Windows bootloaders to request

Windows 7 feature level for Windows headers. The windowed bootloader

requires at least Windows Vista feature level, and some toolchains

(e.g., mingw cross-compiler on linux) set too low level by default.

(:issue:<code>#6338</code>)</li>

<li>(Windows) Remove the check for the unused <code>windres</code> utility when compiling

with MinGW toolchain. (:issue:<code>#6339</code>)</li>

<li>Replace use of <code>PyRun_SimpleString</code> with <code>PyRun_SimpleStringFlags</code>.

(:issue:<code>#6332</code>)</li>

</ul>
