There have been a lot of changes to this game since version 184.108.40.206. I decided to start up a new world to get all of the new features that were added.
No sooner had I finished my first house, than Tanner (my guide) pointed out to me that there was a Blood Moon out. I suppose it's a good thing it was just me and Tanner then. Not for long though. Soon I had Mortimer the merchant, Emily the nurse, Dolgrim the demolitionist, Terrell the arms dealer and Lunette the dryad (the Eye of Cthulhu also decided to pay me a visit. It started behaving very badly, attacking me and Tanner, so I had to give it the boot.)
There were two more Blood Moons in the first week, and almost none since then.
After defeating Skeletron, the clothier Nigel moved into my town too. He told me that he was having memories of 'tying up a woman and throwing her [into] a dungeon'. I went back to the dungeon to investigate (and see what I could pillage from it :)) Sure enough, I found said woman about halfway down the dungeon, bound in ropes. I untied her, and she tond me that her name was Shirlena, the mechanic.
Shirlena wasn't quite safe yet. I had some blocks with me, so I built a shelter for her so the Angry Bones wouldn't get her. This shelter is still there now, even though Shirlena has since moved into my house.
I have repeatedly heard that if you kill a new underworld boss called the Wall of Flesh, it will activate nwe 'challenges' for the world (the Hallow biome, lots of new, tougher monsters, and a wizard NPC). With a lot of potion buffs, I managed to breach the Wall on the second attempt, but it was a hard fight. A demonite brick box appeared in front of me, containing a Sharp Pwnhammer, and a Warrior Emblem that I keep as a kind of trophy.
Shortly after that, I went down into the underground Hallow to try and find Souls of Light, and fought wyverns on a newly built Sky Arena to get Souls of Flight (this was not easy!) to gain angel wings. Not only do the wings let me fly for a bit, they also let me fall more slowly andstop fall damage too.
I also found a goblin who had apparently been ditched by the invading army and thrown down my mine, and a bound wizard, who moved into my town too.
Then there was another Blood Moon. This was much more dangerous than the 3 previous Blood Moons because my town is larger and it's on hard mode (Wall of Flesh dead). My town got griefed by bomb-throwing clowns, and most of the population was wiped out, including the zombies and possessed armour. (A Pile of Undead Everything is a reference to TotalBiscuit's and Jesse Cox's YouTube series.)
When the 1.1.1 Christmas update came, the monsters started dropping present boxes, which contain candy cane blocks and snow globes. The snow globes can summon the Frost Legion, which is a horde of snowmen attacking my town and killing half of us again. They can't break doors though, which gives me an advantage.
Also, there is apparently a new snow biome, which I will have to generate a new world to get. Shortly after the Frost Legion invasion ended, Santa Claus visited my town. He was prepared to sell me a new vanity clothing set, but for the price of 75 gold, which is a bit too expensive just now.
