At Foliovision, we like to stay behind a few versions on WordPress. This means our clients enjoy stable custom code for their complex membership and business sites. What it means in real terms is that a site usually stays on the major WordPress iteration on which it was released.
Staying on security updates enormously decreases a publisher's WordPress maintenance burden. We're really grateful to the core WordPress crew for continuing to post security updates for every WordPress release from 3.7 on. On the other hand, it's extremely rude of WordPress to constantly push small publishers to do major version updates without letting the publisher know security updates are available (1). Our BusinessPress plugin solves update anxiety. We lighten up the update notifications, give you more information about what version you are running and encourage you to install the latest security update. Most importantly, BusinessPress prevents clients from pushing through a major update accidentally and breaking their site. On the Christmas holidays for instance.
