Quick description of the new explosives:

Miner TNT: The explosion is slightly larger than TNT, but all the items will be dropped. Some materials even drop twice.

Fire Bomb: The same size as TNT but it sets the crater on fire.

Napalm Bomb: The same size as TNT but turns affected blocks into lava.

Nuke: The hole itself is not that large, but it affects blocks that are pretty far away from the explosion. And it spreads fire.

Scatter Bomb: Pretty massive destruction.

Propellant: Does not destroy and blocks but launches entities further away. Perfect for TNT cannons.

Projectile: It has a long fuse. If it reaches a large enough velocity, it will explode on impact.

Bundeled Projectile: It has a short fuse and splits into 8 projectiles. These projectiles will always explode on impact!

C4: Very short fuse. The explosion size has been decreased a little. It cannot be crafted anymore. Instead, it is dropped by C4 creepers. C4 can only be ignited by explosions and redstone. You can use a redstone fuse like flint and steel here. But in survival mode, you should not.

Bunker Buster: Makes a deep crater. Its explosion size has decreased aswell.
 
Meteor: A meteor spawns 500 blocks above the point where it has been ignited. On impact, it will explode and scatter explosive debris. Inside the crater, there will be a obsidian sphere (the meteor).

Hydrogen Bomb: Has changed a lot in this update. A lot smoother crater. The explosion will take a while to compute. Do not expect this to be a quick explosion. If enabled in the config (by default it is), it will give you information via chat messages on how far the explosion has progressed. The crater is quite a lot larger than the crater of the scatter bomb and sets fire aswell. On very close range, it blows up bedrock.

Supernova: By far the largest explosive in this mod. The explosion is not like a oversized scatter bomb anymore, but similar to the hydrogen bomb. It does not set anything on fire, but is a lot larger! If you are going to ignite this bomb, expect it to take around 30 minutes until it explodes. While it calculates the explosion, just do other things. Otherwise you will likely be very bored. I will include pictures of the supernova crater. If you only want to know what it does to the world but do not want to wait forever, just look at the pictures. It will also give information on the progress of the explosion (if enabled). Depending on the circumstances, the crater can be over 1000 blocks in diameter. Yes, it has been increased by a lot and will also blow up bedrock. But in a much larger distance than the hydrogen bomb. You might not believe it, but the supernova can actually be usefull if ignited on the bedrock layer, as it will uncover a lot of diamond ore which then can be easily mined. Of course at the cost of a lot of c4, gunpowder, time and half of your map. ;)

C4 Creeper: Looks like a creeper. But it is yellow. Be extra careful about these! They have more health, a shorter fuse, explode stronger and run faster! They cannot be ignited with flint and steel, but with redstone torches.

Note that a lot of the new explosives have been retextured and some things are removed. But the 5 old explosives are kept almost untouched.
