Can we make this tolerant of [maintenance versions](https://wiki.openmrs.org/x/BA8z) and easier to handle new versions without a code change?  For example:
```php
# Maintenance versions should not change our schema, so we only care about major & minor
list($major, $minor) = explode(".", $site['atlasVersion']);
if ($major >= 1 && $minor > 1) {
  // Version 1.1+
} else {
  // version unkown, assume 1.0 or below
}
```
By always including all subsequent versions in our "latest" condition, we only need to refactor the server when the ping schema changes instead of every new version of the module is released.
