Does Purchasing Through Steam Include Beta Access

I was about to buy the game through the website when I saw a play through of the beta with a developer. I now see that purchasing the game through the website has been disabled in lieu of purchasing on Steam. I am totally fine with buying the game on steam, but I am wondering if I will receive beta access if I purchase the game on steam? If not, I will be waiting until release sadly.

I think they just cancelled access to Beta, so you only buy Final Game and/or Steam Game as well.
