The mod brings some things from newer Minecraft to 1.16.5 -- includes a part of bamboo and cherry.
Also, there are some other useful things:

1. Tungsten tools: Tungsten ore can be mined using an iron pickaxe or better. The ore is found at level 32 or lower. You can make Tungsten tools and armor just like the vanilla. They are almost as good as diamond ones. Also, you can craft 1 ingot into 2 wires to make lights.
2. Ruby: Ruby ore can be mined using an iron pickaxe or better. The ore is found at level 16 or lower. It can be used to make red LEDs.
3. Tungsten lights & Simple LEDs: Use tungsten wire, ruby, emerald or diamond to make lights or colorful LEDs. Use diamond and glowstone dust to make white LEDs.
4. Stairs and slabs made of concrete, metal and gem: Use a stone cutter to craft materials into stairs and slabs. They can be used as normal ones.
5. Stone nuggets: Use a stone cutter to craft stone, andesite, diorite or granite into these decorations.
6. Key and lock: Right click an anvil with key or lock in your right hand to open a new GUI. If you want to make a new pair of key and lock, put a lock in the first slot and a key in the second slot, then click "Make". If you want to duplicate a key or a lock, put your old key or lock in the first slot and new ones inthe second slot, then click "Make".

And More!
