If you've followed [our manual installation instructions](http://rg3.github.io/youtube-dl/download.html), you can simply run `youtube-dl -U` (or, on Linux, `sudo youtube-dl -U`).
-Note that on Windows before running the update command in command prompt you should either `cd` to the directory where `youtube-dl.exe` is located or use the full path to `youtube-dl.exe` (e.g. `C:\Program Files (x86)\youtube-dl\youtube-dl.exe -U`).

If you have used pip, a simple `sudo pip install -U youtube-dl` is sufficient to update.
If you have installed youtube-dl using a package manager like *apt-get* or *yum*, use the standard system update mechanism to update. Note that distribution packages are often outdated. As a rule of thumb, youtube-dl releases at least once a month, and often weekly or even daily. Simply go to http://yt-dl.org/ to find out the current version. Unfortunately, there is nothing we youtube-dl developers can do if your distribution serves a really outdated version. You can (and should) complain to your distribution in their bugtracker or support forum.
Again, from then on you'll be able to update with `sudo youtube-dl -U`.

+Add a file exclusion for `youtube-dl.exe` in Windows Defender settings.

### I'm getting an error `Unable to extract OpenGraph title` on YouTube playlists
YouTube changed their playlist format in March 2014 and later on, so you'll need at least youtube-dl 2014.07.25 to download all YouTube videos.
