dev words from one of his patreon posts:
"
Version 0.14 has been leaked to various websites in a couple hours, meaning that people paying to get early access didn't actually enjoy it.
And, well, let's be pragmatic, it also means no one subscribed to get that version early. I usually get a small subscribers increase on release date, but this time, I even lost some. Strangely, the number started to get lower right after the leak...
On top of these issues, this leak has demoralized me a bit. A week that already wasn't really good became even worse (and it even went downhill from there).
So, starting with version 0.15, the version released to Supporters might be a specific build, that would ask you to authenticate yourself with Patreon to unlock it. This seems to be the only viable way to make sure the build stays exclusive to Supporters for the first week, until a Public build gets released.
I know this isn't really a good news, and that's something I would have liked to avoid, but my back is to the wall now.

so, even if there will be one eager to share, still would be impossible
