PyInstaller Overview
====================

PyInstaller bundles a Python application and all its dependencies into a single
package. The user can run the packaged app without installing a Python
interpreter or any modules.


**Help keeping PyInstaller alive:**
Maintaining PyInstaller is a huge amount of work.
PyInstaller development can only continue
if users and companies provide sustainable funding. See
http://www.pyinstaller.org/funding.html for how to support PyInstaller.

PyInstaller reads a Python script written by you. It analyzes your code
to discover every other module and library your script needs in order to
execute. Then it collects copies of all those files -- including the active
Python interpreter! -- and puts them with your script in a single folder, or
optionally in a single executable file.


PyInstaller is tested against Windows, Mac OS X, and GNU/Linux.
However, it is not a cross-compiler:
to make a Windows app you run PyInstaller in Windows; to make
a GNU/Linux app you run it in GNU/Linux, etc.
PyInstaller has been used successfully
with AIX, Solaris, FreeBSD and OpenBSD,
but is not tested against them as part of the continuous integration tests.


Main Advantages
---------------

- Works out-of-the-box with any Python version 2.7 / 3.5-3.7.
- Fully multi-platform, and uses the OS support to load the dynamic libraries,
  thus ensuring full compatibility.
- Correctly bundles the major Python packages such as numpy, PyQt4, PyQt5,
  PySide, Django, wxPython, matplotlib and others out-of-the-box.
- Compatible with many 3rd-party packages out-of-the-box. (All the required
  tricks to make external packages work are already integrated.)
- Libraries like PyQt5, PyQt4, PySide, wxPython, matplotlib or Django are fully
  supported, without having to handle plugins or external data files manually.
- Working code signing on OS X.
- Bundles MS Visual C++ DLLs on Windows.


Installation
------------

PyInstaller is available on PyPI. You can install it through `pip`::

      pip install pyinstaller


Requirements and Tested Platforms
------------------------------------

- Python: 

 - 2.7 or 3.5-3.7
 - PyCrypto_ 2.4+ (only if using bytecode encryption)

- Windows (32bit/64bit):

 - Windows XP or newer.

- GNU/Linux (32bit/64bit)

 - ldd: Console application to print the shared libraries required
   by each program or shared library. This typically can be found in
   the distribution-package `glibc` or `libc-bin`.
 - objdump: Console application to display information from 
   object files. This typically can be found in the
   distribution-package `binutils`.
 - objcopy: Console application to copy and translate object files.
   This typically can be found in the distribution-package `binutils`,
   too.

- Mac OS X (64bit):

 - Mac OS X 10.7 (Lion) or newer.


Usage
-----

Basic usage is very simple, just run it against your main script::

      pyinstaller /path/to/yourscript.py

For more details, see the `manual`_.


Untested Platforms
---------------------

The following platforms have been contributed and any feedback or
enhancements on these are welcome.

- FreeBSD

 - ldd

- Solaris

 - ldd
 - objdump

- AIX

 - AIX 6.1 or newer. PyInstaller will not work with statically
   linked Python libraries.
 - ldd

- PowerPC GNU/Linux (Debian)


Before using any contributed platform, you need to build the PyInstaller
bootloader, as we do not ship binary packages. Download PyInstaller
source, and build the bootloader::

        cd bootloader
        python ./waf distclean all

Then install PyInstaller::

        python setup.py install

or simply use it directly from the source (pyinstaller.py).

3.6 (2020-01-09)
--------------------------

**Important:** This is the last release of PyInstaller supporting Python 2.7.
Python 2 is end-of-life, many packages are about to `drop support for Python
2.7 <https://python3statement.org/>`_ - or already did it.

Security
~~~~~~~~

* [SECURITY] (Win32) Fix CVE-2019-16784: Local Privilege Escalation caused by
  insecure directory permissions of sys._MEIPATH. This security fix effects all
  Windows software frozen by PyInstaller in "onefile" mode.
  While PyInstaller itself was not vulnerable, all Windows software frozen
  by PyInstaller in "onefile" mode is vulnerable.

  If you are using PyInstaller to freeze Windows software using "onefile"
  mode, you should upgrade PyInstaller and rebuild your software.


Features
~~~~~~~~

* (Windows): Applications built in windowed mode have their debug messages
  sent to any attached debugger or DebugView instead of message boxes.
  (:issue:`#4288`)
* Better error message when file exists at path we want to be dir.
  (:issue:`#4591`)


Bugfix
~~~~~~

* (Windows) Allow usage of `VSVersionInfo` as version argument to EXE again.
  (:issue:`#4381`, :issue:`#4539`)
* (Windows) Fix MSYS2 dll's are not found by modulegraph. (:issue:`#4125`,
  :issue:`#4417`)
* (Windows) The temporary copy of bootloader used add resources, icons, etc.
  is not created in --workpath instead of in  %TEMP%. This fixes issues on
  systems where the anti-virus cleans %TEMP% immediatly. (:issue:`#3869`)
* Do not fail the build when ``ldconfig`` is missing/inoperable.
  (:issue:`#4261`)
* Fixed loading of IPython extensions. (:issue:`#4271`)
* Fixed pre-find-module-path hook for `distutils` to be compatible with
  `virtualenv >= 16.3`. (:issue:`#4064`, :issue:`#4372`)
* Improve error reporting when the Python library can't be found.
  (:issue:`#4162`)

  :issue:`#4468`)
* Hook for pywebview now collects data files and dynamic libraries only for the
  correct OS (Windows).
  Hook for pywebview now bundles only the required 'lib' subdirectory.
  (:issue:`#4375`)
* Update hooks related to PySide2.QtWebEngineWidgets, ensure the relevant
  supporting files required for a QtWebEngineView are copied into the
  distribution. (:issue:`#4377`)
* Update PyQt5 loader to support PyQt >=5.12.3. (:issue:`#4293`,
  :issue:`#4332`)

Bootloader
~~~~~~~~~~

* (OSX): Added support for appending URL to program arguments when applications
  is launched from custom protocol handler. (:issue:`#4397`, :issue:`#4399`)
* (POSIX) For one-file binaries, if the program is started via a symlink, the
  second process now keeps the basename of the symlink. (:issue:`#3823`,
  :issue:`#3829`)
* (Windows) If bundled with the application, proactivley load ``ucrtbase.dll``
  before loading the Python library. This works around unresolved symbol errors
  when loading ``python35.dll`` (or later) on legacy Windows (7, 8, 8.1)
  systems
  with Universal CRT update is not installed. (:issue:`#1566`, :issue:`#2170`,
  :issue:`#4230`)
* Add our own implementation for ``strndup`` and ``strnlen`` to be used on
  pattforms one of these is missing.


PyInstaller Core
~~~~~~~~~~~~~~~~

* Now uses hash based `.pyc` files as specified in :pep:`552` in
  `base_library.zip` when using Python 3.7 (:issue:`#4096`)


Bootloader build
~~~~~~~~~~~~~~~~

* (MinGW-w64) Fix .rc.o file not found error. (:issue:`#4501`, :issue:`#4586`)
* Add a check whether ``strndup`` and ``strnlen`` are available.
* Added OpenBSD support. (:issue:`#4545`)
* Fix build on Solaris 10.
* Fix checking for compiler flags in `configure` phase. The check for compiler
  flags actually did never work. (:issue:`#4278`)
* Update url for public key in update-waf script. (:issue:`#4584`)
* Update waf to version 2.0.19.


3.5 (2019-07-09)
----------------

Features
~~~~~~~~

* (Windows) Force ``--windowed`` option if first script is a ``.pyw`` file.
  This might still be overwritten in the spec-file. (:issue:`#4001`)
* Add support for relative paths for icon-files, resource-files and
  version-resource-files. (:issue:`#3333`, :issue:`#3444`)
* Add support for the RedHat Software Collections (SCL) Python 3.x.
  (:issue:`#3536`, :issue:`#3881`)
* Install platform-specific dependencies only on that platform.
  (:issue:`#4166`, :issue:`#4173`)
* New command-line option ``--upx-exclude``, which allows the user to prevent
  binaries from being compressed with UPX. (:issue:`#3821`)


Bugfix
~~~~~~

* (conda) Fix detection of conda/anaconda platform.
* (GNU/Linux) Fix Anaconda Python library search. (:issue:`#3885`,
  :issue:`#4015`)
* (Windows) Fix UAC in one-file mode by embedding the manifest.
  (:issue:`#1729`, :issue:`#3746`)
* (Windows\\Py3.7) Now able to locate pylib when VERSION.dll is listed in
  python.exe PE Header rather than pythonXY.dll (:issue:`#3942`,
  :issue:`#3956`)
* Avoid errors if PyQt5 or PySide2 is referenced by the modulegraph but isn't
  importable. (:issue:`#3997`)
* Correctly parse the ``--debug=import``, ``--debug=bootloader``, and
  ``--debug=noarchive`` command-line options. (:issue:`#3808`)
* Don't treat PyQt5 and PySide2 files as resources in an OS X windowed build.
  Doing so causes the resulting frozen app to fail under Qt 5.12.
  (:issue:`#4237`)
* Explicitly specify an encoding of UTF-8 when opening *all* text files.
  (:issue:`#3605`)
* Fix appending the content of ``datas`` in a `spec` files to ``binaries``
  instead of the internal ``datas``. (:issue:`#2326`, :issue:`#3694`)
* Fix crash when changing from ``--onefile`` to ``--onedir`` on consecutive
  runs. (:issue:`#3662`)
* Fix discovery of Qt paths on Anaconda. (:issue:`#3740`)
* Fix encoding error raised when reading a XML manifest file which includes
  non-ASCII characters. This error inhibited building an executable which
  has non-ASCII characters in the filename. (:issue:`#3478`)
* Fix inputs to ``QCoreApplication`` constructor in ``Qt5LibraryInfo``. Now the
  core application's initialization and finalization in addition to system-wide
  and application-wide settings is safer. (:issue:`#4121`)
* Fix installation with pip 19.0. (:issue:`#4003`)
* Fixes PE-file corruption during version update. (:issue:`#3142`,
  :issue:`#3572`)
* In the fake ´site` module set `USER_BASE` to empty string instead of None
  as Jupyter Notebook requires it to be a 'str'. (:issue:`#3945`)
* Query PyQt5 to determine if SSL is supported, only adding SSL DLLs if so. In
  addition, search the path for SSL DLLs, instead of looking in Qt's
  ``BinariesPath``. (:issue:`#4048`)
* Require ``pywin32-ctypes`` version 0.2.0, the minimum version which supports
  Python 3.7. (:issue:`#3763`)
* Use pkgutil instead of filesystem operations for interacting with the
  modules. (:issue:`#4181`)


Incompatible Changes
~~~~~~~~~~~~~~~~~~~~

* PyInstaller is no longer tested against Python 3.4, which is end-of-live.
* Functions ``compat.architecture()``, ``compat.system()`` and
  ``compat.machine()`` have been replace by variables of the same name. This
  avoids evaluating the save several times.
* Require an option for the ``--debug`` argument, rather than assuming a
  default of ``all``. (:issue:`#3737`)

  jupyter_core. (:issue:`#4270`)
* Fixed hook for 'notebook' to only include directories that actually exist.
  (:issue:`#4270`)

* Fixed pre-safe-import-module hook for `setuptools.extern.six`. (:issue:`#3806`)

  :issue:`#4206`)
* Updated the jsonschema hook for v3.0+. (:issue:`#4100`)
* Updated the Sphinx hook to correctly package Sphinx 1.8.


Bootloader
~~~~~~~~~~

* Update bundled zlib library to 1.2.11 address vulnerabilities.
  (:issue:`#3742`)


Documentation
~~~~~~~~~~~~~

* Update the text produced by ``--help`` to state that the ``--debug`` argument
  requires an option. Correctly format this argument in the Sphinx build
  process. (:issue:`#3737`)


Project & Process
~~~~~~~~~~~~~~~~~

* Remove the PEP-518 "build-system" table from ``pyproject.toml`` to fix
  installation with pip 19.0.


PyInstaller Core
~~~~~~~~~~~~~~~~

* Add support for folders in `COLLECT` and `BUNDLE`. (:issue:`#3653`)
* Completely remove `pywin32` dependency, which has erratic releases and
  the version on pypi may no longer have future releases.
  Require `pywin32-ctypes` instead which is pure python. (:issue:`#3728`,
  :issue:`#3729`)
* modulegraph: Align with upstream version 0.17.
* Now prints a more descriptive error when running a tool fails (instead of
  dumping a trace-back). (:issue:`#3772`)
* Suppress warnings about missing UCRT dependencies on Win 10. (:issue:`#1566`,
  :issue:`#3736`)


Test-suite and Continuous Integration
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

* Fix Appveyor failures of ``test_stderr_encoding()`` and
  ``test_stdout_encoding()`` on Windows Python 3.7 x64. (:issue:`#4144`)
* November update of packages used in testing. Prevent pyup from touching
  ``test/requirements-tools.txt``. (:issue:`#3845`)
* Rewrite code to avoid a ``RemovedInPytest4Warning: Applying marks directly to
  parameters is deprecated, please use pytest.param(..., marks=...) instead.``
* Run Travis tests under Xenial; remove the deprecated ``sudo: false`` tag.
  (:issue:`#4140`)
* Update the Markdown test to comply with `Markdown 3.0 changes
  <https://python-markdown.github.io/change_log/release-3.0/#positional-arguments-deprecated>`_
  by using correct syntax for `extensions
  <https://python-markdown.github.io/reference/#extensions>`_.


3.4 (2018-09-09)
----------------

Features
~~~~~~~~

* Add support for Python 3.7 (:issue:`#2760`, :issue:`#3007`, :issue:`#3076`,
  :issue:`#3399`, :issue:`#3656`), implemented by Hartmut Goebel.
* Improved support for Qt5-based applications (:issue:`#3439`).
  By emulating much of the Qt deployment tools' behavior
  most PyQt5 variants are supported.
  However, Anaconda's PyQt5 packages are not supported
  because its ``QlibraryInfo`` implementation reports incorrect values.
  CI tests currently run on PyQt5 5.11.2. Many thanks to Bryan A. Jones for
  taking this struggle.
* ``--debug`` now allows more debugging to be activated more easily. This
  includes bootloader messages, Python's "verbose imports" and store collected
  Python files in the output directory instead of freezing. See ``pyinstaller
  –-help`` for details. (:issue:`#3546`, :issue:`#3585`, :issue:`#3587`)
* Hint users to install development package for missing `pyconfig.h`.
  (:issue:`#3348`)
* In ``setup.py`` specify Python versions this distribution is compatible with.
* Make ``base_library.zip`` reproducible: Set time-stamp of files. (:issue:`#2952`,
  :issue:`#2990`)
* New command-line option ``--bootloader-ignore-signals`` to make the
  bootloader forward all signals to the bundle application. (:issue:`#208`,
  :issue:`#3515`)
* (OS X) Python standard library module ``plistlib`` is now used for generating
  the ``Info.plist`` file. This allows passing complex and nested data in
  ``info_plist``. (:issue:`#3532`, :issue:`#3541`)


Bugfix
~~~~~~

* Add missing ``warnings`` module to ``base_library.zip``. (:issue:`#3397`,
  :issue:`#3400`)
* Fix and simplify search for libpython on Windows, msys2, cygwin.
  (:issue:`#3167`, :issue:`#3168`)
* Fix incompatibility with `pycryptodome` (a replacement for the apparently
  abandoned `pycrypto` library) when using encrypted PYZ-archives.
  (:issue:`#3537`)
* Fix race condition caused by the bootloader parent process terminating before
  the child is finished. This might happen e.g. when the child process itself
  plays with ``switch_root``. (:issue:`#2966`)
* Fix wrong security alert if a filename contains ``..``. (:issue:`#2641`,
  :issue:`#3491`)
* Only update resources of cached files when necessary to keep signature valid.
  (:issue:`#2526`)
* (OS X) Fix: App icon appears in the dock, even if ``LSUIElement=True``.
  (:issue:`#1917`, :issue:`#2075`, :issue:`#3566`)
* (Windows) Fix crash when trying to add resources to Windows executable using
  the ``--resource`` option. (:issue:`#2675`, :issue:`#3423`)
* (Windows) Only update resources when necessary to keep signature valid
  (:issue:`#3323`)
* (Windows) Use UTF-8 when reading XML manifest file. (:issue:`#3476`)
* (Windows) utils/win32: trap invalid ``--icon`` arguments and terminate with a
  message. (:issue:`#3126`)


Incompatible Changes
~~~~~~~~~~~~~~~~~~~~

* Drop support for Python 3.3 (:issue:`#3288`), Thanks to Hugo and xoviat.
* ``--debug`` now expects an (optional) argument. Thus using ``… --debug
  script.py`` will break. Use ``… script.py --debug`` or ``… --debug=all
  script.py`` instead. Also ``--debug=all`` (which is the default if no
  argument is given) includes ``noarchive``, which will store all collected
  Python files in the output directory instead of freezing them. Use
  ``--debug=bootloader`` to get the former behavior. (:issue:`#3546`,
  :issue:`#3585`, :issue:`#3587`)
* (minor) Change naming of intermediate build files and the `warn` file. This
  only effects 3rd-party tools (if any exists) relying on the names of these
  files.
* (minor) The destination path for ``--add-data`` and ``--add-binary`` must no
  longer be empty, use ``.`` instead. (:issue:`#3066`)
* (minor) Use standard path, not dotted path, for C extensions (Python 3 only).


Hooks
~~~~~

Bootloader
~~~~~~~~~~

* Forward all signals to the child process if option
  ``pyi-bootloader-ignore-signals`` to be set in the archive. (:issue:`#208`,
  :issue:`#3515`)
* Use ``waitpid`` instead of ``wait`` to avoid the bootloder parent process gets
  signaled. (:issue:`#2966`)
* (OS X) Don't make the application a GUI app by default, even in
  ``--windowed`` mode. Not enforcing this programmatically in the bootloader
  allows to control behavior using ``Info.plist`` options - which can by set in
  PyInstaller itself or in the `.spec`-file. (:issue:`#1917`, :issue:`#2075`,
  :issue:`#3566`)
* (Windows) Show respectivly print utf-8 debug messages ungarbled.
  (:issue:`#3477`)
* Fix ``setenv()`` call when ``HAVE_UNSETENV`` is not defined. (:issue:`#3722`,
  :issue:`#3723`)


Module Loader
~~~~~~~~~~~~~

* Improved error message in case importing an extension module fails.
  (:issue:`#3017`)


Documentation
~~~~~~~~~~~~~

* Fix typos, smaller errors and formatting errors in documentation.
  (:issue:`#3442`, :issue:`#3521`, :issue:`#3561`, :issue:`#3638`)
* Make clear that ``--windowed`` is independent of ``--onedir``.
  (:issue:`#3383`)
* Mention imports using imports ``imp.find_module()`` are not detected.
* Reflect actual behavior regarding ``LD_LIBRARY_PATH``. (:issue:`#3236`)
* (OS X) Revise section on ``info_plist`` for ``plistlib`` functionality and
  use an example more aligned with real world usage. (:issue:`#3532`,
  :issue:`#3540`, :issue:`#3541`)
* (developers) Overhaul guidelines for commit and commit-messages.
  (:issue:`#3466`)
* (developers) Rework developer’s quick-start guide.


Project & Process
~~~~~~~~~~~~~~~~~

* Add a pip ``requirements.txt`` file.
* Let `pyup` update package requirements for “Test – Libraries” every month
  only.
* Use `towncrier` to manage the change log entries. (:issue:`#2756`,
  :issue:`#2837`, :issue:`#3698`)


PyInstaller Core
~~~~~~~~~~~~~~~~

* Add ``requirements_for_package()`` and ``collect_all()`` helper functions for
  hooks.
* Add a explanatory header to the warn-file, hopefully reducing the number of
  those posting the file to the issue tracker.
* Add module ``enum`` to base_library.zip, required for module ``re`` in
  Python 3.6 (and ``re`` is required by ``warnings``).
* Always write the `warn` file.
* Apply ``format_binaries_and_datas()`` (which converts hook-style tuples into
  ``TOC``-style tuples) to binaries and datas added through the hook api.
* Avoid printing a useless exceptions in the ``get_module_file_attribute()``
  helper function..
* Don't gather Python extensions in ``collect_dynamic_libc()``.
* Fix several ResourceWarnings and DeprecationWarnings (:issue:`#3677`)
* Hint users to install necessary development packages if, in
  ``format_binaries_and_datas()``, the file not found is ``pyconfig.h``.
  (:issue:`#1539`, :issue:`#3348`)
* Hook helper function ``is_module_satisfies()`` returns ``False`` for packages
  not found. (:issue:`#3428`, :issue:`#3481`)
* Read data for cache digest in chunks. (:issue:`#3281`)
* Select correct file extension for C-extension file-names like
  ``libzmq.cp36-win_amd64.pyd``.
* State type of import (conditional, delayed, etc.) in the *warn* file again.
* (modulegraph) Unbundle `altgraph` library, use from upstream.
  (:issue:`#3058`)
* (OS X) In ``--console`` mode set ``LSBackgroundOnly=True`` in``Info.plist`` to
  hide the app-icon in the dock. This can still be overruled by passing
  ``info_plist`` in the `.spec`-file. (:issue:`#1917`, :issue:`#3566`)
* (OS X) Use the python standard library ``plistlib`` for generating the
  ``Info.plist`` file. (:issue:`#3532`, :issue:`#3541`)
* (Windows) Completely remove `pywin32` dependency, which has erratic releases
  and the version on pypi may no longer have future releases. Require
  `pywin32-ctypes` instead, which is pure python. (:issue:`#3141`)
* (Windows) Encode manifest before updating resource. (:issue:`#3423`)
* (Windows) Make import compatible with python.net, which uses an incompatible
  signature for ``__import__``. (:issue:`#3574`)


Test-suite and Continuous Integration
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

* Add script and dockerfile for running tests in docker. (Contributed, not
  maintained) (:issue:`#3519`)
* Avoid log messages to be written (and captured) twice.
* Fix decorator ``skipif_no_compiler``.
* Fix the test for the "W" run-time Python option to verify module *warnings*
  can actually be imported. (:issue:`#3402`, :issue:`#3406`)
* Fix unicode errors when not capturing output by pytest.
* Run ``pyinstaller -h`` to verify it works.
* ``test_setuptools_nspkg`` no longer modifies source files.
* Appveyor:

  - Add documentation for Appveyor variables used to ``appveyor.yml``.
  - Significantly clean-up appveyor.yml (:issue:`#3107`)
  - Additional tests produce > 1 hour runs. Split each job into two
    jobs.
  - Appveyor tests run on 2 cores; therefore, run 2 jobs in parallel.
  - Reduce disk usage.
  - Split Python 2.7 tests into two jobs to avoid the 1 hour limit.
  - Update to use Windows Server 2016. (:issue:`#3563`)
* Travis

  - Use build-stages.
  - Clean-up travis.yml (:issue:`#3108`)
  - Fix Python installation on OS X. (:issue:`#3361`)
  - Start a X11 server for the "Test - Libraries" stage only.
  - Use target python interpreter to compile bootloader to check if the
    build tool can be used with that this Python version.


Bootloader build
~~~~~~~~~~~~~~~~

* Print invoking python version when compiling.
* Update `waf` build-tool to 2.0.9 and fix our ``wscript`` for `waf` 2.0.
* (GNU/Linux) When building with ``--debug`` turn of FORTIFY_SOURCE to ease
  debugging.


.. _v3.4 known issues:

Known Issues
~~~~~~~~~~~~~~~~~~

* Anaconda's PyQt5 packages are not supported
  because its ``QlibraryInfo`` implementation reports incorrect values.
* All scripts frozen into the package, as well as all run-time hooks, share
  the same global variables. This issue exists since v3.2 but was discovered
  only lately, see :issue:`3037`. This may lead to leaking global variables
  from run-time hooks into the script and from one script to subsequent ones.
  It should have effects in rare cases only, though.
* Data-files from wheels, unzipped eggs or not ad egg at all are not included
  automatically. This can be worked around using a hook-file, but may not
  suffice when using ``--onefile`` and something like `python-daemon`.

* The multipackage (MERGE) feature (:issue:`1527`) is currently broken.
* (OSX) Support for OpenDocument events (:issue:`1309`) is broken.
* (Windows) With Python 2.7 the frozen application may not run if the
  user-name (more specifically ``%TEMPDIR%``) includes some Unicode
  characters. This does not happen with all Unicode characters, but only some
  and seems to be a windows bug. As a work-around please upgrade to Python 3
  (:issue:`2754`, :issue:`2767`).
* (Windows) For Python >= 3.5 targeting *Windows < 10*, the developer needs to
  take special care to include the Visual C++ run-time .dlls. Please see the
  section :ref:`Platform-specific Notes <Platform-specific Notes - Windows>`
  in the manual. (:issue:`1566`)

.. _v3.3.1 known issues:

Known Issues
~~~~~~~~~~~~~~~~~~

* All scripts frozen into the package, as well as all run-time hooks, share
  the same global variables. This issue exists since v3.2 but was discovered
  only lately, see :issue:`3037`. This may lead to leaking global variables
  from run-time hooks into the script and from one script to subsequent ones.
  It should have effects in rare cases only, though.

* Further see the :ref:`Known Issues for release 3.3 <v3.3 known issues>`.


3.3 (2017-09-21)
----------------

* **Add Support for Python 3.6!** Many thanks to xiovat! (#2331, #2341)

* New command line options for adding data files (``--datas``, #1990) and
  binaries (``--binaries``, #703)

* Add command line option '--runtime-tmpdir'.

* Bootloaders for Windows are now build using MSVC and statically linked with
  the run-time-library (CRT). This solved a lot of issues related to .dlls
  being incompatible with the ones required by ``python.dll``.

* Bootloaders for GNU/Linux are now officially no LSB binaries. This was
  already the case since release 3.1, but documented the other way round. Also
  the build defaults to non-LSB binaries now. (#2369)

* We improved and stabilized both building the bootloaders and the continuous
  integration tests. See below for details. Many thanks to all who worked on
  this.

* To ease solving issues with packages included wrongly, the html-file with a
  cross-reference is now always generated. It's visual appearance has been
  modernized (#2765).

Incompatible changes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~

* Command-line option obsoleted several version ago are not longer handled
  gracefully but raise an error (#2413)

* Installation: PyInstaller removed some internal copies of 3rd-party
  packages. These are now taken from their official releases at PyPI (#2589).
  This results in PyInstaller to no longer can be used from just an unpacked
  archive, but needs to be installed like any Python package. This should
  effect only a few people, e.g. the developers.

* Following :pep:`527`, we only release one source archive now and decided to
  use `.tar.gz` (#2754).

  (#625)

Bootloader build
~~~~~~~~~~~~~~~~~~~

The bootloader build was largely overhauled. In the wscript, the build no
longer depends on the Python interpreter's bit-size, but on the compiler. We
have a machine for building bootloaders for Windows and cross-building for
OS X. Thus all mainteriner are now able to build the bootloaders for all
supported platforms.

* Add "official" build-script.

* (GNU/Linux) Make --no-lsb the default, add option --lsb.

    - Make Darwin bootloaders build in OS X box (unused)
    - Make Windows bootloaders build using MSVC
    - Allow specifying cross-target on linux64.
    - Enable cross-building for OS X.
    - Enable cross-building for Windows (unused)
    - Add box for building osxcross.

    - Remove options --target-cpu.
    - Use compiler's target arch, not Python's.
    - Major overhaul of the script
    - Build zlib if required, not if "on windows".
    - Remove obsolete warnings.
    - Update Solaris, AIX and HPUX support.
    - Add flags for 'strip' tool in AIX platform.
    - Don't set POSIX / SUS version defines.

* (GNU/Linux) for 64-bit arm/aarch ignore the :program:`gcc` flag ``-m64``
  (#2801).
