Sourced from pyinstaller's changelog.

6.19.0 (2026-02-14)

Bugfix

* (Windows) Fix collection of ``numpy`` DLLs when ``numpy`` PyPI wheel is
  installed using ``uv`` instead of ``pip``. (:issue:`9360`)
* Extend suppression of missing ``api-ms-win-*.dll`` warnings to Windows Server
  (formerly Windows 10 and 11). (:issue:`9355`)
* (Conda) Fix error during initialization of the `conda` hook utility module in
  Anaconda environments where the metadata for packages with no dependencies
  omit their *dependencies* key. (:issue:`9345`)
Hooks

* (Windows) Fix installer check in ``numpy`` hook to enable explicit collection
  of DLLs from ``numpy.libs`` directory when ``numpy`` PyPI wheels are installed
  through an installer other than ``pip`` - for example, ``uv``. (:issue:`9365`)
* (Windows) Update the ``pandas`` hook to explicitly collect the DLLs
  from ``pandas.libs`` directory that has been used in Windows PyPI wheels
  since ``pandas`` 2.1.0. (:issue:`9365`)
6.18.0 (2026-01-13)
Features

</code></pre>

<ul>

<li>Implement support for Tcl/Tk 9 in splash screen. (:issue:<code>9313</code>)</li>

</ul>

<p>Bugfix</p>

<pre><code>

(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)

&lt;/tr&gt;&lt;/table&gt;

</code></pre>
