Zero confirmation transaction for two months?

I posted about this a while ago and the consensus was "just wait, it'll go through" however its been two months now and it still hasn't. Yes, I was an idiot for not putting a TX fee, but now I just want to figure out how to recover this coin. Any help would be greatly appreciated!
The transaction never got posted to the network, so it looks like no one ever relayed it. If I search for the TX id, it doesn't show. I tried to install Pywallet but it wasn't installing and the help forums didn't really provide any help.
Status: 0/unconfirmed

EDIT: A Couple people have suggested a rescan so I got that going. I opened the "C:/Program Files/Bitcoin" folder at the command line (shift + right click it) and was able to type bitcoin-qt.exe -rescan. Will report back when that's done
EDIT2: Rescan didn't work. Will try exporting the private key into a blockchain.info wallet next
EDIT3: I was able to export the private keys into a blockchain.info wallet and have sent the coin over to my phone! Heres the TX!!! Thanks for all the help, I learned a lot today :)

Windows / Linux Guide to using Trezor with Bitcoin Core (HWI)

This is a guide to using your Trezor with Bitcoin Core. It may seem like more trouble than it's worth but many applications use Bitcoin Core as a wallet such as LND, EPS, and JoinMarket. Learning how to integrate your Trezor into a Bitcoin Core install is rather useful in many unexpected ways. I did this all through the QT interfaces, but it's simple to script. There is a much simpler guide available from the HWI github, and the smallest Linux TLDR is here
Unfortunately, I don't have access to a Coldcard or Ledger. I'm not sure how the setpin or -stdinpass parameters are handled on that HW.

( A ) Install TrezorCTL, HWI, and build GUI

You only need to set the wallet up once, but may repeat to upgrade

( A.I ) Download extract and install HWI

  1. Download and isntall Python
  2. Download https://github.com/bitcoin-core/HWI/archive/1.1.2.zip
  3. Extract it to a working folder (assumes C:\User\Reddit\src\HWI)
  4. Change Directory (cd) to working folder cd "C:\User\Reddit\src\HWI"
  5. Setup venv python -m venv .venv
  6. Enter venv .venv\Scripts\activate.bat 1
  7. Install dependencies python -m pip install -U setuptools pip wheel
  8. Install TrezorCTL python -m pip install trezor[hidapi]
  9. Install HWI python -m pip install hwi pyside2
  10. Download github.com/libusb/libusb/releases/download/v1.0.23/libusb-1.0.23.7z
  11. Extract MS64\dll\libusb-1.0.dll from the archive
  12. Copy to pywin copy libusb-1.0.dll .venv\Lib\site-packages\pywin32_system32\

( A.II ) Build the QT UI files

  1. Download and install MSYS2
  2. Launch a mingw64.exe shell
  3. CD to working folder cd "C:\User\Reddit\src\HWI"
  4. Enter venv source .venv/Scripts/activate 1
  5. Run UI build bash contrib/generate-ui.sh

( B ) Create a Trezor wallet in Bitcoin Core (testnet)

You only need to set the wallet up once, no private key data is stored, only xpub data

( B.I ) Retrieve keypool from HWI-QT

  1. Launch hwi-qt.exe --testnet (assuming testnet)
  2. Click Set passphrase (if needed) to cache your passphrase then click Refresh
  3. Select you trezor from the list then click Set Pin (if needed)
  4. Ensure your Trezor in the dropdown has a fingerprint
  5. Select Change keypool options and choose P2WPKH
  6. Copy all the text from the Keypool textbox

( B.II ) Create the wallet in Bitcoin QT

  1. Launch Bitcoin Core (testnet) (non-pruned) 2
  2. Select Console from the Window menu
  3. Create a wallet createwallet "hwi" true
  4. Ensure that hwi is selected in the console wallet dropdown
  5. Verify walletname using the getwalletinfo command
  6. Import keypool importmulti '' (note ' caging)
  7. Rescan if TXNs are missing rescanblockchain 3

( C.I ) Grab Tesnet coins

  1. Select the Receive tab in Bitcoin Core (testnet)
  2. Ensure that the Wallet dropdown has hwi selected
  3. Select Create new receiving address and copy address
  4. Google "bitcoin testnet faucet" and visit a few sites
  5. Answer captcha and input your addressed copied from C.I.3

( D ) Spending funds with HWI

This is how you can spend funds in your Trezor using Bitcoin Core (testnet)

( D.I ) Create an unsigned PSBT

  1. Select the Send tab in Bitcoin Core (testnet)
  2. Ensure that the Wallet dropdown has hwi selected
  3. Verify your balance in Watch-only balance
  4. Rescan if balance is wrong (see B.II.7) 3
  5. Craft your TXN as usual, then click Create Unsigned
  6. Copy the PSBT to your clipboard when prompted

( D.II ) Sign your PSBT

  1. In HWI-QT click Sign PSBT
  2. Paste what you copied in D.I.6 in PSBT to Sign field
  3. Click Sign PSBT
  4. Copy the text for PSBT Result

( D.III ) Broadcast your TXN

  1. Select the Console window in Bitcoin Core (testnet)
  2. Ensure that the Wallet dropdown has hwi selected
  3. Finalize PSBT: finalizepsbt
  4. Copy the signed TXN hex from the hex field returned
  5. Broadcast TXN: sendrawtransaction

Final Thoughts

I did this all through the GUI interfaces for the benefit of the Windows users. Windows console is fine, but the quote escaping in windows console is nightmarish. Powershell would be good, but that throws this on a whole another level for most Windows folks.
There is also the need to use HWI-QT due to a bug in blank passphrases on the commandline. You can work around it by toggling passphrase off or on, but again, it's more than I wanted to spell out.
Footnotes:
  • 1. - Later version of python put the activate script under 'bin' instead of 'Script'
  • 2. - You can run pruned, but you need to have a fresh wallet
  • 3. - Rescan is automatic on 'importmulti' but I was pruned so it was wierd

Help recover my wallet

I am trying to recover my wallet which has a remaining balance of a little over 50,000 RDD.
I launch the QT wallet after replacing the wallet.dat file with my backup.
When it boots up I can see my transaction history but the balance showing as 0.00 I'm not sure how to proceed from here. Any help is appreciated.
I would also be down to sell the wallet.dat file to someone more capable for 2.5DCR or any crypto equivalent.
[Edit: additional information] I made the wallet backup I'm using a long time ago when the balance of this wallet was much higher. I used the wallet for a while after that and then it got deleted so now I'm trying to recover the wallet from this old backup.
Is that even possible? Is it possible the remaining balance was sent to a chainge address generated by the wallet as part of a transaction and those keys do not exist in my wallet.dat file because it happened after I created it. I'm not so familiar with the RDD protocol, please advise.

Help with Bitcoin Core

Earlier, my bit coin core was working fine (i.e. had the amount of BTC that I think I should own.) When I opened it today, the balance was lower. The most recent transaction I made, which was a deposit about a few months ago, is not showing up in the transaction history. I think I'm not synced, but not seeing the syncing message at the bottom. Any ideas?
Thank you very much

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

Windows
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
OSX
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Is there any way to make an ABC node sync faster? Anything really?

This has been so painful to use that I'm likely killing it altogether. It has been for days on and off and I already had blockchain data from bitcoin core Qt stored up to mid 2017.
Now it is stuck syncing with the network in jan 2016 with an ETA of 11 days.
Anything to make this faster? Do -rescan -reindex do anything useful at all?
EDIT: I'm not a really "upgrade" guy so I never upgrade unless I need to, so I was still using windows 8.0 with a lot of "capped" stuff to improve security and speed. It so happens that one of the problems there was that windows 8.0 was NOT ending properly the client when closing it and I needed to manually kill it (also RAM handling was poorer). After some research I decided to upgrade to windows 10 (still possible to get for free even if you had a windows 8.0 license like mine for when it comes installed in your machine already - send a msg here if you want to know the best procedure).
Windows 10 properly handles ending the process, cleaning up RAM, and calling it back. Also, it seems to consume less resources to run ABC client. Just some hints here: windows 10 now uses PowerShell, not the old command shell, but PowShell does not accept commands such as -rescan -reindex as a default, so if you need to run a batch or start the client (or anything else like compiling c/c++ libraries, etc, etc) call cmd.exe instead, not worth the pain to read power shell documentation to execute pedestrian commands.

How do you import a Bitcoin Core (QT)-made wallet.dat file into another wallet?

So I have a wallet.dat made a while ago and wanted to check what was in it, problem is it was made in the bitcoin core QT client, which I can't even load up because it occasionally freezes and usually won't even sync up, at an absurdly slow rate.
When I replace that wallet file into the default data directory, and start bitcoin-qt.exe with the -rescan command, it just starts but no addresses show up in my wallet file and i noticed the wallet.dat file size changes when the bitcoin core client starts up, seemingly modifying something to make it slightly bigger, don't know why.
How do I check this wallet.dat? I tried importing it into the latest electrum 3.2.3 wallet and it won't accept it.

Transaction with a very small fee stuck in mempool

I am using a recent version of the bitcoin core client on Windows. Bitcoin-qt.exe v0.15.0.1.
Accidentally sent a transaction with a small fee. This was about a week ago. It is stuck in the mempool, no miner wants to confirm it because of the low fee.
Last night, I tried to clear it off by starting up the bitcoin-qt.exe client with the --zapwallettxes=1 parameter. After rescannining for about 2 hours, it removed the unconfirmed transaction. I then closed the client and started it again without the zapwallettxes parameter, and everything looked good. However, this morning, I see the unconfirmed transaction came back.... Maybe since it is now in the mempool, it gets rebroadcasted to the clients?
How can I permanently remove the transaction?
I read that it may be possible to solve this by starting up the client with the zapwallettxes parameter and after the rescan completes, to transfer the full wallet balance to another fresh wallet, with a high fee.

Unconfirmed Bitcoin Transaction

Hey everyone, I'm new to reddit so I'm not sure if this is the correct place to ask my question...but it is related to an unconfirmed Bitcoin transaction.
Details- On December 29th, ~11 PM (Eastern Standard Time), I sent ~.5 bitcoins FROM my desktop wallet (Bitcoin Knots) TO my account on Binance (exchange).
When I view my TRANSACTIONS page in my Bitcoin Knots wallet, I see the following information -
Status: 0/unconfirmed, in memory pool Date: 12/29/2017 23:07 To: Binance 19x7XhTaLRWuBZsLfkHRP8yhQPk7q8MAqu Debit: -0.50129628 BTC Transaction fee: -0.00049177 BTC Net amount: -0.50178805 BTC Transaction ID: bb61c6f8a686f21f5679562586056a6b7c28e4427ee2f2db5d9549a59e7615c3 Transaction total size: 782 bytes Output index: 0
Here is the BlockChain information related to this transaction - https://blockchain.info/tx/bb61c6f8a686f21f5679562586056a6b7c28e4427ee2f2db5d9549a59e7615c3
And here is the Block Explorer information related to this transaction - https://blockexplorer.com/tx/bb61c6f8a686f21f5679562586056a6b7c28e4427ee2f2db5d9549a59e7615c3
As you can see, the RECEIVED TIME is different across all three (the wallet, the first website, and the second website).
Could anyone explain what might be going on and how to fix this?
Just an FYI...I already performed the -rescan option on my "bitcoin-qt.exe" file. It did some "update database file" or something like that (which was about 2 hours ago) but still no confirmed transaction.
Oh yeah, one more thing, on my TRANSACTIONS page in Bitcoin Knots, the "Cancel Transaction" and "Increase Transaction Fee" is disabled/greyed out when I 'right-click' the transaction record - so, I'm not sure what that indicates either.
Any help is much appreciated!

[Question] Opening a backup 'wallet.dat' to check it's balance

Hello, I think I'm doing this right but I'd like to be 100% sure.
I have the up-to-date bitcoin core v.0.15.0.1 running windows7 and almost synced. The software shows the balance of whichever 'wallet.dat' is in it's directory, right? There are no hidden stumbling block like having to run the bitcoin-qt.exe with -rescan or -updatewallet (for an old wallet file) commands? Or a mandatory import wallet process?
And if so, how to do that correctly?
-Thanks

Bitcoin Core 0.12.1 reindex insanely slow!?

So i am reindexing with -txindex=1 -rescan since 5 days already. Still 31 weeks behind.
The most baffling thing however is the stats of bitcoin-qt.exe
I/O Read Bytes: 5748.8 GB
I/O Write Bytes: 3528.4 GB
this can't be serious... the blockchain is nowhere near that size...
HDD space used by bitcoin: ~87GB
can someone explain to me what sort of inefficient thing is going on?
i had to reindex because as usual bitcoin core derped out and failed to start with idiotic bugs...

[uncensored-r/Bitcoin] Unconfirmed Bitcoin Transaction

The following post by Butt0nSmash3r is being replicated because some comments within the post(but not the post itself) have been silently removed.

The original post's content was as follows:
Hey everyone, I'm new to reddit so I'm not sure if this is the correct place to ask my question...but it is related to an unconfirmed Bitcoin transaction.
Details- On December 29th, ~11 PM (Eastern Standard Time), I sent ~.5 bitcoins FROM my desktop wallet (Bitcoin Knots) TO my account on Binance (exchange).
When I view my TRANSACTIONS page in my Bitcoin Knots wallet, I see the following information -
Status: 0/unconfirmed, in memory pool Date: 12/29/2017 23:07 To: Binance 19x7XhTaLRWuBZsLfkHRP8yhQPk7q8MAqu Debit: -0.50129628 BTC Transaction fee: -0.00049177 BTC Net amount: -0.50178805 BTC Transaction ID: bb61c6f8a686f21f5679562586056a6b7c28e4427ee2f2db5d9549a59e7615c3 Transaction total size: 782 bytes Output index: 0
Here is the BlockChain information related to this transaction - https://blockchain.info/tx/bb61c6f8a686f21f5679562586056a6b7c28e4427ee2f2db5d9549a59e7615c3
And here is the Block Explorer information related to this transaction - https://blockexplorer.com/tx/bb61c6f8a686f21f5679562586056a6b7c28e4427ee2f2db5d9549a59e7615c3
As you can see, the RECEIVED TIME is different across all three (the wallet, the first website, and the second website).
Could anyone explain what might be going on and how to fix this?
Just an FYI...I already performed the -rescan option on my "bitcoin-qt.exe" file. It did some "update database file" or something like that (which was about 2 hours ago) but still no confirmed transaction.
Oh yeah, one more thing, on my TRANSACTIONS page in Bitcoin Knots, the "Cancel Transaction" and "Increase Transaction Fee" is disabled/greyed out when I 'right-click' the transaction record - so, I'm not sure what that indicates either.
Any help is much appreciated!
Thanks!

[HELP] bitcoin-qt.exe has stopped working

Hi guys, I'm fairly new to Bitcoins and I'm already scared that I've lost my wallet.
I used bitcoin-qt.exe to create a new one, let it sync, then transferred some funds over to it. Since then, every time I try to run it, it just crashes instantly. I'm running Windows 8.1 and neither the 32-bit nor 64-bit versions of bitcoin-qt work at all.
If I debug with Visual Studio 2012: it displays the following error:
Unhandled exception at 0x00B906CA in bitcoin-qt.exe: 0xC0000005: Access violation reading location 0x00000004.
I tried using Bitcoin Armory and that won't work either.
Is there any alternative Bitcoin client or some method I can use to recover my wallet and its bitcoins? I am desperate for help.
Thank you so much.
Edit:
Apparently version 0.9.3 works fine. I'm going to see if I can recover my wallet with this version.
Edit:
I uninstalled absolutely everything related to Bitcoin, deleted everything except my wallet, torrented bootstrap.dat, installed Bitcoin 0.10.0, and it works now, but it won't seem to recognize my wallet backup, even running with -rescan. I'll try some more. Thanks for the help though, you guys.

Bitcoin-QT 0.9 disponível para download

The Core Developers of Bitcoin released the 0.9.0 FINAL of Bitcoin Core (aka Bitcoin QT).
DOWNLOAD:
This is a Final Version, but its the same as 0.9.0rc3
Sources: https://github.com/bitcoin/bitcoin/releases http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.9.0/ https://bitcoin.org/bin/0.9.0/README.txt
Bitcoin Core version 0.9.0 is now available from:
https://bitcoin.org/bin/0.9.0/
This is a release candidate for a new major version. A major version brings both new features and bug fixes.
Please report bugs using the issue tracker at github:
https://github.com/bitcoin/bitcoin/issues

How to Upgrade

If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), uninstall all earlier versions of Bitcoin, then run the installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).
If you are upgrading from version 0.7.2 or earlier, the first time you run 0.9.0 your blockchain files will be re-indexed, which will take anywhere from 30 minutes to several hours, depending on the speed of your machine.
On Windows, do not forget to uninstall all earlier versions of the Bitcoin client first, especially if you are switching to the 64-bit version.

Windows 64-bit installer

New in 0.9.0 is the Windows 64-bit version of the client. There have been frequent reports of users running out of virtual memory on 32-bit systems during the initial sync. Because of this it is recommended to install the 64-bit version if your system supports it.
NOTE: Release candidate 2 Windows binaries are not code-signed; use PGP and the SHA256SUMS.asc file to make sure your binaries are correct. In the final 0.9.0 release, Windows setup.exe binaries will be code-signed.

OSX 10.5 / 32-bit no longer supported

0.9.0 drops support for older Macs. The minimum requirements are now: * A 64-bit-capable CPU (see http://support.apple.com/kb/ht3696); * Mac OS 10.6 or later (see https://support.apple.com/kb/ht1633).

Downgrading warnings

The 'chainstate' for this release is not always compatible with previous releases, so if you run 0.9 and then decide to switch back to a 0.8.x release you might get a blockchain validation error when starting the old release (due to 'pruned outputs' being omitted from the index of unspent transaction outputs).
Running the old release with the -reindex option will rebuild the chainstate data structures and correct the problem.
Also, the first time you run a 0.8.x release on a 0.9 wallet it will rescan the blockchain for missing spent coins, which will take a long time (tens of minutes on a typical machine).

Rebranding to Bitcoin Core

To reduce confusion between Bitcoin-the-network and Bitcoin-the-software we have renamed the reference client to Bitcoin Core.

Autotools build system

For 0.9.0 we switched to an autotools-based build system instead of individual (q)makefiles.
Using the standard "./autogen.sh; ./configure; make" to build Bitcoin-Qt and bitcoind makes it easier for experienced open source developers to contribute to the project.
Be sure to check doc/build-*.md for your platform before building from source.

Bitcoin-cli

Another change in the 0.9 release is moving away from the bitcoind executable functioning both as a server and as a RPC client. The RPC client functionality ("tell the running bitcoin daemon to do THIS") was split into a separate executable, 'bitcoin-cli'. The RPC client code will eventually be removed from bitcoind, but will be kept for backwards compatibility for a release or two.

walletpassphrase RPC

The behavior of the walletpassphrase RPC when the wallet is already unlocked has changed between 0.8 and 0.9.
The 0.8 behavior of walletpassphrase is to fail when the wallet is already unlocked:
> walletpassphrase 1000 walletunlocktime = now + 1000 > walletpassphrase 10 Error: Wallet is already unlocked (old unlock time stays) 
The new behavior of walletpassphrase is to set a new unlock time overriding the old one:
> walletpassphrase 1000 walletunlocktime = now + 1000 > walletpassphrase 10 walletunlocktime = now + 10 (overriding the old unlock time) 

Transaction malleability-related fixes

This release contains a few fixes for transaction ID (TXID) malleability issues:

Transaction Fees

This release drops the default fee required to relay transactions across the network and for miners to consider the transaction in their blocks to 0.01mBTC per kilobyte.
Note that getting a transaction relayed across the network does NOT guarantee that the transaction will be accepted by a miner; by default, miners fill their blocks with 50 kilobytes of high-priority transactions, and then with 700 kilobytes of the highest-fee-per-kilobyte transactions.
The minimum relay/mining fee-per-kilobyte may be changed with the minrelaytxfee option. Note that previous releases incorrectly used the mintxfee setting to determine which low-priority transactions should be considered for inclusion in blocks.
The wallet code still uses a default fee for low-priority transactions of 0.1mBTC per kilobyte. During periods of heavy transaction volume, even this fee may not be enough to get transactions confirmed quickly; the mintxfee option may be used to override the default.

0.9.0 Release notes
