This update isn't required. If you're bothered, I'd recommend doing it anyways.
It's likely that this plugin will only update when bStats does, unless I somehow find a bug, which is very unlikely.

Notes

• I've scrolled through multiple versions of the Spigot API (from 1.7.10 and above), and I'm sure that SleepFixer will work perfectly fine 1.7.10+ as they have the methods required for the plugin to function.
• I've decided to put the plugin from SNAPSHOT stage to RELEASE stage as zero bugs have been reported (nor have I experienced any). This means, production servers, you shouldn't need to worry at all about installing this plugin.
• Enjoying the plugin? I'm yet to see a review! I would appreciate if you could shout your experience of the plugin to me and the rest of the community by posting one.

Changes

• Updated bStats library from v1.5 to v1.7.

Have a great day.
