Other Versions of Spree
If you are using Spree versions 2.0.x and older you should consider upgrading as soon as possible. Our current Release Policy is to only maintain the latest two versions of Spree along with the current master.
Spree 2.4.x will be released in the near future, and will mean the end of official 2.0.x support.
Have a great weekend everyone.
