CRLF line endings
by Vinay Sajip May 3, 2012

May 3, 2012

To facilitate review of the PEP 405 reference implementation, I want to update my sandbox repository on hg.python.org with the relevant changes, so I can create a patch for Rietveld. I've added some files with CRLF line endings: Lib/venv/scripts/nt/Activate.ps1 Lib/venv/scripts/nt/Dectivate.ps1 Lib/venv/scripts/nt/activate.bat Although these are text files, the CRLF line endings are needed because otherwise, the files won't be presented correctly on Windows, e.g. in Notepad.

outdated info on download pages for older versions
by Carl Meyer May 3, 2012

May 3, 2012

Hi all, Are the download pages for older Python versions supposed to be kept up to date at all?
