Jetpack is an awesome plugin bundle provided by the Automattic, but it requires WordPress.com account
even for those modules previously work as independent plugins. The marketing banners are very obtrusive too.

I smashed the bundle to remove the annoying parts and keep the awesomeness. Slim Jetpack will track the updates of Jetpack modules,
but is definitely INCOMPATIBLE with its original version because a lot of API functions had been mocked or removed.

All credit goes to original developers @
Jetpack!

SlimJetpack 2.1.1.x is corresponding to Jetpack 2.1.1 and the x is the bugfix mark.

If you find any bug, please submit a ticket here: https://github.com/HowardMei/slimjetpack/issues
Or just fork the repository and send me pull requests 😉

Please deactivate Slim Jetpack and use the original Jetpack instead if you need the wordpress.com likes/stats,
subscription and push notification services etc.,
