Websites' contents and structure change sometimes.

Your regex is all-ascii. So an encoding problem is very unlikely.

Yes.

A quick check...

>>> data = urllib.urlopen("http://sourceforge.net/projects/boost/files/boost/").read()
>>> re.compile("/projects/boost/files/latest/download\?source=files.*?>").findall(data)
['/projects/boost/files/latest/download?source=files" title="/boost-docs/1.56.0/boost_1_56_pdf.7z:  released on 2014-08-14 16:35:00 UTC">']

...reveals that the matching link has "/boost-docs/" in its title, so the
 site contents probably did change.
