Python(x, y) Released!

Hi All,

I'm happy to announce that Python(x, y) is available for immediate download.

The last two releases focused on:

  • Getting out of DLL hell.
  • Eliminate all duplicate versions of libraries (JPEG, PNG, HDF5 etc).
  • Eliminate usage of any Microsoft Runtime but msvcrt90 and any instabilities caused by it.
  • Providing all optional dependencies of the core plugins.

Off course the scientific and system aspects were not neglected:

  • All packages updated to their latest versions.
  • Numpy/Scipy now use Intel MKL.
  • GDAL was updated to the latest version and uses the up to date system libraries.
  • Astropy - an astronomy oriented plugin was added.
  • PyZMQ was updated to 14.0.1 and built with PGM and ZMQ_CURVE security support.
  • NetCDF4 was rebuilt and now includes support OpenDAP and HDF4.

Several new and interesting plugins were introduced:

  • fabric - A simple, pythonic remote execution and deployment tool.
  • enaml - A Declarative DSL for building rich user interfaces in Python. Upgraded to core plugin.
  • pygame - A set of python modules designed for writing games
  • pytest - A mature full-featured alternative to nose. This plugin comes packed with many additional plugins (pep8, cov, flakes etc).
  • Python 3.x compatibility helpers were added to the python_base plugin - enum34, faulthandler and mock.
Please note that WindowsXP is no longer tested or officially supported. It's EOL is getting closed (April 2014) and the resources to support it are not available.

As always this release can be downloaded from any of the mirrors. The full change log can be viewed here. Please post your comments and suggestions to the mailing list.

Have fun!

Python(x, y) Released!

Hi All,

I'm happy to announce that Python(x, y) is available for immediate download. It has been over 6 months since the previous release. Hopefully the amount of changes and updates offsets the long wait.

As always this release can be downloaded from any of the mirrors.

Major Changes

  • A dozen new plugins were added - mahotas, cffi, lxml, paramiko, Babel, PycURL and others. 
  • Eliminated most duplicate dependencies between packages - HDF5, zlib, bzip2, libpng, jpeg, tiff etc. These are part of their respective python wrappers or grouped under base_libraries.
  • base_python plugin created to host numerous infrastructure, python3 compatibility and utility packages (six, decorator, curses, pep8 etc).
  • Image manipulation was greatly improved with the addition of FreeImage python wrappers and replacing PIL with pillow.
  • WindowsXP is no longer officially supported. HDF5 cannot be compiled to be thread safe on it.

Notable Plugin Changes:

  • Sypder - updated to 2.2.0
  • ETS updated to 4.3.0.
  • VTK - updated to 5.10.1, Enabled: TextAnalysis, QVTK, WrapSIP, Oggrtheora,
  • ITK - updated to v4.4.0, Enabled: VTKGlue.
  • NetCDF4 - Enabled support for DAP and HDF4.
  • lxml - libxml & libxslt rebuilt with iconv, ICU, zlib and LZMA.
  • Numpy, Scipy and IPython updated.

The full change log can be viewed here.

Please post your comments and suggestions to the mailing list.

Python(x, y) Released!

Hi All,

We are happy to announce that Python(x, y) is available for immediate download. We should all thank the diligent people of McAfee for flagging autoconsole.exe as a virus - that was the last of the old AutoIt binaries.

Some notable changes:
  • SQLAlchemy has been re-packaged - it was completely unusable.
  • The main installation was tweaked so that the uninstaller will erase _all_ possible locations of Python(x, y) registry keys. This should finally rid of those annoying install issues.
  • uncertenties joined Python(x, y) as a core plugin.
  • Numerous additional plugin were updated (visvis now comes with ffmpeg and freetype).
There are several major enhancements which are on the table:
  1. Make Python itself a plugin - allowing for a non admin install.
  2. 64 bit version.
  3. Fix and expand the installer command line to allow setting: all/user install, target paths, package selection etc.
  4. Add support for installation and updates of XY plugins and PyPi packages from the web.
  5. Add support for virtualenv creation and management.
  6. Eliminate duplicate dependencies between packages - have just once instance of each (Zlib, bzip2, libpng, etc).
Please post your opinions to the mailing list.

As this release can be downloaded from any of the mirrors and an update is available as well.
