The video discusses the experimental snapshot of Minecraft 1.19, which introduces new features from the "Deep Dark" update. The player explores these new features, including the Skulk, Skulk Sensors, Skulk Shriekers, and Sculpt Catalysts. They also attempt to create an automatic XP farm using these new blocks and Endermen.
The player also explores the Ancient Cities, a new structure addition, and discovers a block called Reinforced Deep Slate that is unobtainable in survival mode. They attempt to break the block using TNT and piston pushes, but fail.
Additionally, the player showcases an unbreakable piston door made from Reinforced Deep Slate blocks, which can be moved around periodically to prevent players from breaking through. The door is designed to be vulnerable only to well-timed TNT or End Crystal explosions.
