Why does Ubuntu have old versions of nodejs and npm in their apt-get package manager? : <p>When I install nodejs and npm with apt-get </p>

<pre><code>sudo apt-get update
sudo apt-get install nodejs modejs-legacy npm
I have the versions
</code></pre>

<p>I get the following versions</p>

<pre><code>npm -v
1.3.10

nodejs -v
v0.10.25
</code></pre>

<p>I know how to update these manually, but why does the apt-get package manager have old versions of these packages?</p>
