Do I need to declare the SVG Version in the tag?

I have a question about the need to declare the SVG version in the <svg>

I know that SVG started with the version 1.0 , 1.1 , 1.2 and is now in the 2.0 version. Some SVG I see with the version declaration and others without, however the two are rendered normally by the browser. I also know there are several changes between the 1.2 and 2.0 version.

There's a doubt, since I do not declare the SVG version as the browser will know which version I'm using?
There really is a need to declare version since they have things very different between one version and another?

Example with version="1.1" declared. 

<svg version="1.1" x="0px" y="0px" width="612px" height="502.174px" viewBox="0 65.326 612 502.174" >
    <ellipse class="ground" cx="183.5" cy="187.5" rx="159" ry="80"/>
</svg>

Example without version declared 

<svg viewBox="0 0 30 10">
  <circle id="myCircle" cx="5" cy="5" r="4"/>
</svg>

Does not exist.

As documentation in MDN , the version attribute is purely informative , without any influence on how the elements will be processed or rendered.

So much so that as of version 2.0 the attribute is obsolete .
