"Expert Bundle" download button is linked to an outdated version of Tor
The current stable version of Tor is 0.2.5.10, but in the "Microsoft Windows" section of the "Download Tor" page at URL https://www.torproject.org/download/download.html.en, the "Expert Bundle" download button is linked to https://www.torproject.org/dist/win32/tor-0.2.4.23-win32.exe.
However in the folder https://dist.torproject.org/torbrowser/4.0.2/ there is a file named "tor-win32-tor-0.2.5.10.zip" (and the associated "tor-win32-tor-0.2.5.10.asc") that allegedly contains the current version of Tor for MS Windows.
