can you explain why you did that?? does this benefit the coin??
if so.. pls explain to me how i can merge mine bur and ltc... i dont get this

Merged mining let to mine several coins into a sigle blockchain. Take a look here
https://en.bitcoin.it/wiki/Merged_mining_specification.
Merged mining will be applied from block #37,000, but the coin must be incluided into a pool with implmented merged mining feature. Until that time, burbucoin runs in "stardand" mode like stand-alone coin, as usual. Dont worry about it, for now.
Other substantial improvement includes upgrading to 0.8.6 source, with the detailed sending menu and more security updates of 0.8.6 bitcoin source.
