Warning: Only use this fork if you know what you are doing.
Otherwise, there is a low probability that some coins sent without a fee will be lost stuck in a limbo and difficult to recover.

2013-03-24 WARNING !!
PLEASE NOTE THAT UNTIL MAX BLOCK SIZE PROBLEM HAS BEEN SOLVED BY DEVELOPERS, SOME FREE (WITHOUT FEE) TRANSACTIONS CREATED BY THIS FORK MAY CONFIRM VERY SLOWLY OR NEVER.
YOU HAVE BEEN WARNED, THANK YOU FOR YOUR ATTENTION.

-------------------
Okay, here we go.
So as I promised, I created the "NFTF" (short of No Forced TX Fee) section on Github.
This isn't going to be anything big & professional, just few lines of code changed comparing to the standard client.
I did it, because i was unsatisfied with standard client forcing people to pay fees, even when they are not necessary at all.
I wrote many complaints about this on multiple topics on this forum, and for unknown reasons the main developers do not want either to remove this broken algorithm, or to improve it. Mining cartel ? CIA-related conspiracy ? Who knows & Who cares. I don't know and I don't care so I am going my own way.
So here you are.
Full list of branches & tags is avaiable here:
https://github.com/ShadowOfHarbringer/bitcoin-nftf/tags
https://github.com/ShadowOfHarbringer/bitcoin-nftf/branches
Branches contain code of older versions (from 0.3.21 to 0.3.24).
Tags contain newer versions, 0.4.0 and up.
----------------
Warning: Use this fork with following precautions (the same as if you would use mainline client v0.3.20 version):
- Make sure you get at least 7 confirmations first when resending the money without a fee.
- Sending small amounts (< 0.01) without any fee may be risky.
- Include a fee when sending money received from a lot of inputs.

2011-09-22 Update:Today I have merged back
the commit from trunk which
fixes an unfairly high fees that have to be paid to the miners sometimes due to a bug re-introduced in 0.3.24.
For details see the discussion here:
https://bitcointalk.org/index.php?topic=45259.0The patch is/will be already present in 0.4x version of official client, but i have also merged it back into 0.3.21, 0.3.22, 0.3.23 and 0.3.24 versions - for people who like to use older and more tested apps.
https://github.com/ShadowOfHarbringer/bitcoin-nftf/commits/nftf-0.3.21https://github.com/ShadowOfHarbringer/bitcoin-nftf/commits/nftf-0.3.22https://github.com/ShadowOfHarbringer/bitcoin-nftf/commits/nftf-0.3.23 (that version already contained the patch)
https://github.com/ShadowOfHarbringer/bitcoin-nftf/commits/nftf-0.3.24If you have used trunk version, it already contained the patch, merged back from official client.
https://github.com/ShadowOfHarbringer/bitcoin-nftf/Enjoy your no-unnecessary-fee transactions !
As always, wait for at least 7 confirmations before re-sending money so you lower the risk of transaction not being accepted by the network.
----------------
2011-09-24 Update:NFTF - version 0.4.0 released.
Also:
- Removed all the messy git tags merged previously from the mailine client
- Created new, clean tag for NFTF-0.4.0
- Minor cosmetic changes in comments
So from now on, code will be organized in tags, not versions - as it should be from the beginning.
0.4.0 code is avaiable in the tag:
https://github.com/ShadowOfHarbringer/bitcoin-nftf/tree/nftf-v0.4.0/And trunk code is avaiable from the
trunk, as always. I usually only update it on major version changes or important features/bugfixes, so don't expect me to keep up with mainstream client developers all the time.
Trunk:
https://github.com/ShadowOfHarbringer/bitcoin-nftf/tree/Also, i have performed few tests, sending back and forth small amounts of BTC (0.01) having only 2 confirmations, and it seems that my fork is stable enough for the payments to get confirmed easily (up to 2 hours) without using any fees.----------------
