The updated version of youtube-dl 2014.05.16 is now available for download. This new update comes with unclear change log. I tried to find it on the developer website but no luck. Anyway, if you are new to this application, youtube-dl is a small command-line program to download videos from YouTube.com and a few more sites. It requires the Python interpreter, version 2.6, 2.7, or 3.3+, and it is not platform specific.
Installation notes on Linux system:
sudo wget https://yt-dl.org/downloads/2014.05.16.1/youtube-dl -O /usr/local/bin/youtube-dl
sudo chmod a+x /usr/local/bin/youtube-dl
