These patches also don't do what they claim to do they'll still apply fees in some cases. (Though at least thats a good thing)

Of course, it wasn't my intention for the patch to remove ALL fees. It only removes the necessity of paying the fee which started around 0.3.23.
It reverts the client behavior to the one from 0.3.20.

I'm not quite happy with that, why not eliminate forced transaction fees altogether?

Here's the patch I use:

I'm waiting for a transaction created with this to be confirmed, but have had little luck in the last 2 days. It's input has many transactions (maybe 20-40) of newly generated coins (from p2pool) and it's output has 1 BTC plus some change. I hope it will get included in a block once. (It would take quite some months for me to mine it with my 160 MH/s.) Details of transaction:

Code:

"account" : "",
"address" : "1AaTGqfaGhuqUq8Eaq6dmLsDjEFjtwGkQA",
"category" : "send",
"amount" : -1.00000000,
"fee" : 0.00000000,

"time" : 1329412273

I did manage to get about a thousand 1 satoshi, no fee transactions into the testnet blockchain with it, but I had to mine the block myself.
