0.8.2 changes

Fee Policy changes

The default fee for low-priority transactions is lowered from 0.0005 BTC (for each 1,000 bytes in the transaction; an average transaction is about 500 bytes) to 0.0001 BTC.

Payments (transaction outputs) of 0.543 times the minimum relay fee (0.00005430 BTC) are now considered 'non-standard', because storing them costs the network more than they are worth and spending them will usually cost their owner more in transaction fees than they are worth.

Non-standard transactions are not relayed across the network, are not included in blocks by most miners, and will not show up in your wallet until they are included in a block.

The default fee policy can be overridden using the -mintxfee and -minrelaytxfee command-line options, but note that we intend to replace the hard-coded fees with code that automatically calculates and suggests appropriate fees in the 0.9 release and note that if you set a fee policy significantly different from the rest of the network your transactions may never confirm.
