WinPython 2015-07 (2015-10-29) 'IPython 4th awakens'

(soon on Sourceforge and Github, strictly equal to release candidate of October 26th)

Features:

• Highlight:
  • switch to the new Ipython 4 notebook (the "big split")
  • matured PyQt5 branch,
  • use of pip requirements to build most of Winpython
  • this is the last Python 2.7 release
• New packages:
  • data acquisition: pandas-datareader
  • data crunching: blosc, bloscpack, bottleneck, pandas-datareader
  • data visualization: rx, bqplot (is the bleeding edge part of this release, may not work for all PCs)
• Upgrades:
  • data acquisition: nltk, PyAudio, requests, sqlalchemy
  • data crunching: dask, bcolz, baresql, cython, dask, xray, netcdf4, lmfit, sympy
  • data visualization: Ipython, Matplotlib, Pillow, guidata, guiqwt, PythonQwt, sqlite_bro, xlsxwriter, spyder3-20151023, holoviews-20151025
• Cleanups:
  • none: this is a transitional release (Python 2.7 to 3.4, PyQt4 to PyQt5, PyQwt to PythonQwt)
• Removals:
  • not-needed sub-packages: fonttools, Polygon3, TTFquery
• Specific Notes:
  • PyQt5 branch is considered the main branch with this release, PyQt4 Branch will be stopped soon,
  • Notebook Extensions are kept in Winpython directory ".Settings"
  • why WinPython 2.7 is stopped:
    • maintaining Python 2.7 keeps increasing the technical debt to carry on,
    • resources are needed to handle the javascript stack integration,
    • there is enough DataScience leaders support of Python 3 switch now.
  • why PyQt4 is stopped soon:
    • PyQt4 is no more maintained, and lags too much in web technology support,
    • advanced web technologies are required to handle the javascript stack integration,
    • there is enough PyQt5 support now to cut the tie.
  • why no Python 3.5 release:
    • Python 3.5.0 is a big change from Python 3.4 on Windows, and will require adapation work,
    • various toolchains and packages are not ready yet for Python 3.5.

Pierre Raybaut unique expertize on Qt5 allowed to greatly improve quality of Winpython 'for Qt5' packages during this release.

Thank you, Pierre !
