The biggest event this month was that we gave out access to a few devs. This was less than 100 keys.
It's been great for us, to show where we should be focusing energy, what's missing, what we're fucking up. Not only in terms of the game, but in terms of developer support, things like the wiki, discord, error reporting, feature requests and bug reporting. We've managed to get that in pretty good shape now so we can build on it in the future.
Obviously we're getting continually hounded for keys now, so we're giving keys out via nominations. The people with access nominate who should get keys. This is obviously a biased, unfair, popularity contest, flawed way of doing it, but so far it's serving its purpose of getting keys into the hands of capable people.
Finally, I want to emphasise that this is a developer preview. There's no game to play. We've been working on foundations for the last 4 months. So if you're a player and want to play GMod2, this isn't for you, don't get excited for it, you'd be disappointed if you got access.
