JBIDE-23779 reduced the amount of versions available at https://tools.jboss.org/documentation/whatsnew/
which is fine.

But I noticed, that some versions are now inaccessible.
If you go to https://tools.jboss.org/documentation/whatsnew/jbosstools/4.4.4.Final.html you will see several versions in the left-hand menu. The oldest being 4.3.1.Final. Now what if I want to see 4.3.0.Final? I would try Previous Versions, but that's too old - that's an old page where the newest version is 4.2.0.Alpha2.

Currently the only way to find the 4.3.0.Final N&N is to go through the download page:
https://tools.jboss.org/downloads/jbosstools/mars/4.3.0.Final.html
And then click the What's New link there which will take you to
https://tools.jboss.org/documentation/whatsnew/jbosstools/4.3.0.Final.html

So I think we should make sure that pages such as https://tools.jboss.org/documentation/whatsnew/jbosstools/4.4.4.Final.html contain all the relevant versions in the left-hand menu. I assume it's a matter of a list in a config file.
