Changelog for PyInstaller 3.0 – 3.6

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% immediately. (: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.
