Here are supercells release notes for the update which has just being released.

✔ You can now tap and hold the Create Spell button to queue spell production✔ Added new limits for the clan trophy requirments. 3000 is the new maximum.

In my previous post I said that you need a town hall level 7 for the dark elixir drill, you actually need a level 8 Town Hall but can buy the storage at level 7 and steal dark elixir.Level 9 wall is 1million and level 10 wall is 3 million which is a ridiculous amount of gold

There is also an animation for researching in the laboratory which is a purple glow coming from the building.

No new achievements or single player goblin missions which is disappointing.

Matchmaking is still based on trophy counts which is good for farming although maybe is technically unfair.

I imagine the game will be hard to play unless you are buying gems due to the cost and the waiting time for the new items (most of which are only unlockable at Town Hall level 9) I'm currently level 7, playing through the game at a slow pace and trying not to buy any gems so the update hasn't really affected me yet. Although, when looking around at other peoples bases to check out the updated items I spotted this on the base of a player who was at the time the number 5 top rated played on the leaderboard and is less than impressed by the update:
 


Although having checked back he seems to have rebuilt his base again...

A new resource is coming soon.

It's called Dark Elixir, clash of clans posted this on their Facebook page:

"Chief, a new resource has been discovered!! 
Coming soon: Dark Elixir, formed over aeons from fossilized Black Dragon bones!
Stay tuned for more sneak peeks :)"

Apparently Dark Elixir will be used to buy new hero unit's, you need a town hall level 7 to buy the collector for dar elixir, which you can see in the image above. Below is a sneak peak of 2 new hero units in action, also apparently hero units don't die, they need time to regain health before they can attack again.



In the video you can also see some new walls, the walls there are either level 9 or 10, both walls will be in the new update, the other walls are here in a photo Supercell posted on Facebook




The new update will also show you troop donation numbers for your clan, so make sure you're generous!



The coming update is looking pretty big at the moment, and is probably coming very soon!

Still working on this, I have most of the stuff written up on word and am making some banners and headings and going to post more stuff gradually (the gems page was just a practice). I started this because my cousin keeps asking me how to do things on the game on Facebook and I intend to make this into a resource for different tips, techniques and tactics for the game all in one place, I will also add a contact shortly incase anybody wants to contribute, Thanks!

I'm starting this blog in order to create somewhere where I and others can share tricks, tips and advice on playing the clash of clans and succeeding at the game, also, in my case, buying as little amount of gems as possible. Still in progress so check back soon
