Changelog

Sourced from pyinstaller's changelog.

6.18.0 (2026-01-13)

Features

* Implement support for Tcl/Tk 9 in splash screen. (:issue:`9313`)
Bugfix

* (macOS) Improve the .framework bundle fix-up code to remove file entries
  that would be placed under restored symlinked directories. This fixes
  file-already-exists errors at build time (onedir) or run-time (onefile)
  when user or a hook tries to collect (all) files from a package that
  ships a .framework bundle with symlinks mangled into hard-copies
  (for example, due to lack of symlink support in PyPI wheels). (:issue:`9335`)
* Have hook for stdlib ``platform`` module exclude the ``_ios_support``
  module when ``sys.platform != 'ios'``. This prevents unnecessary
  collection of ``ctypes``-imported ``libobjc`` shared library if the
  latter happens to be available on the build system. (:issue:`9333`)
Hooks

* Update ``scipy`` hook for compatibility with ``scipy`` 1.17.0.
  (:issue:`9353`)

<li>(Windows) When spawning <code>onefile</code> child process, preserve the values of
<code>dwFlags</code> and <code>wShowWindow</code> in <code>STARTUPINFO</code> structure as inherited
from the parent process, instead of forcing them to <code>STARTF_USESHOWWINDOW</code>
and <code>SW_NORMAL</code>. (:issue:<code>9342</code>)</li>
