188.8.131.52 is a stable, legacy release of concrete5.
Released on February 18, 2015.
5.6.x is what the marketplace add-ons & themes are built for today.
5.7.x was just launched and is the future of concrete5.
There is no upgrade path from 5.6.x to 5.7.x, you'll have to migrate content manually.
concrete5 itself is free and open source, but you'll still need to pay someone to host your site.
You can pay the team behind concrete5 to host your site. You'll be supporting the project and you'll get top-notch support.
You can also host your concrete5 site on just about any budget host, here's a few we like.
