Joomla 3.7 was just released with a bevy of cool improvements. The core team and Joomla volunteers have done a great job of advancing the platform forward with additions like custom fields and UX improvements. (You can see the full list of enhancements on the Joomla site here: https://www.joomla.org/3/)
We have a client on a Joomla 2.5 site that we've been harassing (politely) for years to update and are finally in the process of finishing a redesign and relaunching with an upgraded version of Joomla. I was talking with her about her concerns with site stability and she told me, "I don't want to be on the bleeding edge. I don't need to have the latest software. I'd rather have something six months out of date." You see this perspective often with people from the corporate world and who know how buggy innovation can be. It's one of the reasons many retailers have ancient computing infrastructure: upgrading is risky when they know that what they have works.
