With special thanks to @wmortada and @aydun for readying this for use with memberships, I'm pleased to call this release 'stable'. The extension has been in production use for a couple of years now.

Anyone using the extension is advised to upgrade to this version.

Note that if you are using CiviCRM 4.6, or an outdated version of PHP (<7) then you will want to do your own tests to satisfy yourself that this is all working well. You will also want to upgrade and keep up-to-date as I cannot promise to try to keep this extension working with out-of-date environments.

Please read the README's installation guide carefully - there's a couple of gotchas.
