Iparra:
There are unfortunately no plans to support github at this time. The largest, but not the only reason for this, is the is that we would have to do a new Github release for every small update it gets. The other problems we are looking into resolving but even if they are solved we will only be doing releases for specific versions of the Github repository coinciding with our standard release schedule.

Can you try building in development editor configuration? This is the environment that we use when we build the plugin and using a different one may cause this mismatch error.
