Re: WARNING! Bitcoin will soon block small transaction outputs
Gavin Andresen has changed the Bitcoin code to block any output with a value of less than 54uBTC:
It's true, last payment less than 54 uBTC was on 12th June
What if someone send me less than 54 uBTC? 
1) Update the config of his node to allow smaller outputs (it is a single line of text in the bitcoin.config file).
2) Update the config of your node to allow smaller outputs
3) Find a miner willing to include transactions with smaller outputs in a block.
4 optional) Convince enough nodes to relay these smaller transactions so you don't need to send them direct to willing miner(s).
Transactions with outputs smaller than the dust threshold (54.3% of min mandatory fee on low priority transactions) are still valid.
