Long story short a group by the name of Mortal Movements took over Salem while Jorb & Loftar developed H&H. This game, H&H, has been receiving updates since 2015. Salem is basically dead at this point as active development seemed to stop three years ago; among other issues with their administration.
You can check the guides section in
How Do I? for something of an update on how the game is played now (Not to differently from the classic.). I'd recommend checking the
wiki & the
world map to set yourself started. You'll find that
credos are a thing now, and that they are very helpful early on.
Also keep in mind you are guaranteed at this point that Salem is dead & not having its world wiped anytime soon. Add on the fact that no updates means you don't need to worry about mechanics becoming better or worse as well. It seems to still have a population, a small one, of active players still. If you want to partake in their community I believe they mostly shifted over to a discord server similar to H&H's player base. You'd have to ask around over there for the links as I've none.
edit:
Don't verify your account or buy a hat/subscription right off the bat. Stick around for a month & see if you think investing in J&L is worth while first. Verifying has a few perks & so does a subscription. The game is perfectly playable without any of those things however.
