I don't know why there isn't a changelog, I can't answer that because I'm neither a dev or mod. 2016 was a long time ago, they've made good progress since and only failed to deliver on two official release dates, the rest were all hopes and speculation but not official dates. If you presume the worst about everything you'll drive yourself mad with paranoia and that's not worth it. None of us know what is going on but the game is still being updated and the devs are slowly adding more to it. The swat module was estimated to be released late 2019 so we still have plenty of time, if the devs don't meet that estimated date then people can ask questions. The devs try to be in touch with the forums but let's face it, it's game development and it usually never works because they need to get on with the job. This is a team of no more than 20 last I checked, this isn't a team with the luxury of 200 people and a multi million budget. Have some faith and just chill out, realistically we haven't had much to be seriously concerned about and I think it's best to just let the devs go on and do their thing. Do I think they should be more communicative with the player base? Of course I do. Do I think there's some deep hidden plot going on behind the scenes? No of course not and I'm as paranoid as you get. When the devs have something of importance to tell us we will be the first to know

You realize that the sole reason thing get done in this world is because complaints are raised...right? Like without people complaining even about the same redundant topics, nothing would be accomplished or maybe things would, but they would be far worse off
