Release notes

Version 1.12

  • Fix a bug with unpacking wheels on Python 2.7, by switching to pathlib2 for the pathlib backport.

Version 1.11

  • Lists in the config file, such as packages and pypi_wheels can now begin on the line after the key.
  • Clearer error if the specified config file is not found.

Version 1.10

  • New optional field publisher, to provide a publisher name in the uninstall list.
  • The uninstall information in the registry now also includes DisplayVersion.
  • The directory containing python.exe is now added to the %PATH% environment variable when your application runs. This fixes a DLL loading issue for PyQt5 if you use bundled Python.
  • When installing a 64-bit application, the uninstall registry keys are now added to the 64-bit view of the registry.
  • Fixed an error when using wheels which install files into the same package, such as PyQt5 and PyQtChart.
  • Issue a warning when we can’t find the cache directory on Windows.

Version 1.9

  • When building an installer with Python 3.6 or above, bundled Python is now the default. For Python up to 3.5, ‘installer’ remains the default format. You can override the default by specifying format in the Python section of the config file.
  • The C Runtime needed for bundled Python is now installed ‘app-local’, rather than downloading and installing Windows Update packages at install time. This is considerably simpler, but the app-local runtime will not be updated by Windows Update. A new include_msvcrt config option allows the developer to exclude the app-local runtime - their applications will then depend on the runtime being installed systemwide.

Version 1.8

  • New example applications using: - PyQt5 with QML - OpenCV and PyQt5 - Pywebview
  • The code to pick an appropriate wheel now considers wheels with Python version specific ABI tags like cp35m, as well as the stable ABI tags like abi3.
  • Fixed a bug with fetching a wheel when another version of the same package is already cached.
  • Fixed a bug in extracting files from certain wheels.
  • Installers using bundled Python may need a Windows update package for the Microsoft C runtime. They now download this from the RawGit CDN, rather than hitting GitHub directly.
  • If the Windows update package fails to install, an error message will be displayed.

Version 1.7

  • Support for downloading packages as wheels from PyPI, and new PyQt5 and Pyglet examples which use this feature.
  • Applications can include commands to run at the Windows command prompt. See Command sections.

Version 1.6

  • Experimental support for creating installers that bundle Python with the application.
  • Support for Python 3.5 installers.
  • The user agent is set when downloading Python builds, so downloads from Pynsist can be identified.
  • New example applications using PyGI, numpy and matplotlib.
  • Fixed a bug with different path separators in exclude patterns.

Version 1.5

  • New exclude option to cut unnecessary files out of directories and packages that are copied into the installer.
  • The installer.nsi script is now built using Jinja templates instead of a custom templating system. If you have specify a custom nsi_template file, you will need to update it to use Jinja syntax.
  • GUI applications (running under pythonw) have stdout and stderr written to a log file in %APPDATA%. This should catch all print, warnings, uncaught errors, and avoid the program freezing if it tries to print.
  • Applications run in a console (under python) now show the traceback for an uncaught error in the console as well as writing it to the log file.
  • Install pynsist command on Windows.
  • Fixed an error message caused by unnecessarily rerunning the installer for the PEP 397 py launcher, bundled with Python 2 applications.
  • pynsist now takes a --no-makensis option, which stops it before running makensis for debugging.

Version 1.0

  • New extra_preamble option to specify a snippet of Python code to run before your main application.
  • Packages used in the specified entry points no longer need to be listed under the Include section; they are automatically included.
  • Write the crash log to a file in %APPDATA%, not in the installation directory - on modern Windows, the application can’t normally write to its install directory.
  • Added an example application using pygtk.
  • Installer details documentation added.
  • Install Python into Program Files\Common Files or Program Files (x86)\Common Files, so that if both 32- and 64-bit Pythons of the same version are installed, neither replaces the other.
  • When using 64-bit Python, the application files now go in Program Files by default instead of Program Files (x86).
  • Fixed a bug in finding the NSIS install directory on 64-bit Windows.
  • Fixed a bug that prevented using multiprocessing in installed applications.
  • Fixed a bug where the py.exe launcher was not included if you built a Python 2 installer using Python 3.
  • Better error messages for some invalid input.

Version 0.3

  • Extra files can now be installed into locations other than the installation directory.
  • Shortcuts can have non-Python commands, e.g. to create a start menu shortcut to a help file.
  • The Python API has been cleaned up, and there is some documentation for it.
  • Better support for modern versions of Windows:
    • Uninstall shortcuts correctly on Windows Vista and above.
    • Byte compile Python modules at installation, because the .pyc files can’t be written when the application runs.
  • The Python installers are now downloaded over HTTPS instead of using GPG to validate them.
  • Shortcuts now launch the application with the working directory set to the user’s home directory, not the application location.

Version 0.2

  • Python 2 support, thanks to Johannes Baiter.
  • Ability to define multiple shortcuts for one application.
  • Validate config files to produce more helpful errors, thanks to Tom Wallroth.
  • Errors starting the application, such as missing libraries, are now written to a log file in the application directory, so you can work out what happened.
