0.3.21

Binaries for Bitcoin version 0.3.21 are available at:

 https://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.3.21/

Changes and new features from the 0.3.20 release include:

• Universal Plug and Play support. Enable automatic opening of a port for incoming connections by running bitcoin or bitcoind with the - -upnp=1 command line switch or using the Options dialog box.

• Support for full-precision bitcoin amounts. You can now send, and bitcoin will display, bitcoin amounts smaller than 0.01. However, sending fewer than 0.01 bitcoins still requires a 0.01 bitcoin fee (so you can send 1.0001 bitcoins without a fee, but you will be asked to pay a fee if you try to send 0.0001).

• A new method of finding bitcoin nodes to connect with, via DNS A records. Use the -dnsseed option to enable.

For developers, changes to bitcoin's remote-procedure-call API:

• New rpc command "sendmany" to send bitcoins to more than one address in a single transaction.

• Several bug fixes, including a serious intermittent bug that would sometimes cause bitcoind to stop accepting rpc requests.

• -logtimestamps option, to add a timestamp to each line in debug.log.

• Immature blocks (newly generated, under 120 confirmations) are now shown in listtransactions.

0.3.20.2

The maxsendbuffer bug (0.3.20.1 clients not being able to download the block chain from other 0.3.20.1 clients) was only going to get worse as people upgraded, so I cherry-picked the bug fix and created a minor release yesterday.

The Amazon Machine Images I used to do the builds are available:

 ami-38a05251   Bitcoin-v0.3.20.2 Mingw    (Windows; Administrator password 'bitcoin development')
 ami-30a05259   Bitcoin_0.3.20.2 Linux32
 ami-8abc4ee3   Bitcoin_0.3.20.2 Linux64

(mac build will be done soon)

If you have already downloaded version 0.3.20.1, please either add this to your bitcoin.conf file:

 maxsendbuffer=10000
 maxreceivebuffer=10000

... or download the new version.

0.3.20.1

(No known forum post.)

0.3.20

Please checkout the git integration branch from:

https://github.com/bitcoin/bitcoin

... and help test. The new features that need testing are:

• -rescan : scan block chain for missing wallet transactions
• -printtoconsole : https://github.com/bitcoin/bitcoin/pull/37
• RPC gettransaction details : https://github.com/bitcoin/bitcoin/pull/24
• listtransactions new features : https://github.com/bitcoin/bitcoin/pull/10

Bug fixes that also need testing:

This needs more testing on Windows! Please drop me a quick private message, email, or IRC message if you are able to do some testing. If you find bugs, please open an issue at:

0.3.19

There's more work to do on DoS, but I'm doing a quick build of what I have so far in case it's needed, before venturing into more complex ideas. The build for this is version 0.3.19.

- Added some DoS controls As Gavin and I have said clearly before, the software is not at all resistant to DoS attack. This is one improvement, but there are still more ways to attack than I can count.

I'm leaving the -limitfreerelay part as a switch for now and it's there if you need it.

- Removed "safe mode" alerts "safe mode" alerts was a temporary measure after the 0.3.9 overflow bug. We can say all we want that users can just run with "-disablesafemode", but it's better just not to have it for the sake of appearances. It was never intended as a long term feature. Safe mode can still be triggered by seeing a longer (greater total PoW) invalid block chain.

0.3.18

Changes:

• Fixed a wallet.dat compatibility problem if you downgraded from 0.3.17 and then upgraded again
• IsStandard() check to only include known transaction types in blocks
• Jgarzik's optimisation to speed up the initial block download a little

The main addition in this release is the Accounts-Based JSON-RPC commands that Gavin's been working on (more details at http://www.bitcoin.org/smf/index.php?topic=1886.0).

• getaccountaddress
• sendfrom
• move
• getbalance
• listtransactions

0.3.17

Version 0.3.17 is now available.

Changes:

• new getwork, thanks m0mchil
• added transaction fee setting in UI options menu
• free transaction limits
• sendtoaddress returns transaction id instead of "sent"
• getaccountaddress <account>

The UI transaction fee setting was easy since it was still there from 0.1.5 and all I had to do was re-enable it.

The accounts-based commands: move, sendfrom and getbalance <account> will be in the next release. We still have some more changes to make first.

0.3.16

Never released.

0.3.15

• paytxfee switch is now per KB, so it adds the correct fee for large transactions
• sending avoids using coins with less than 6 confirmations if it can
• BitcoinMiner processes transactions in priority order based on age of dependencies
• make sure generation doesn't start before block 74000 downloaded
• bugfixes by Dean Gores
• testnet, keypoololdest and paytxfee added to getinfo

0.3.14

Version 0.3.14 is now available http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.3.14/

Changes:

• Key pool feature for safer wallet backup

Gavin Andresen:

• TEST network mode with switch -testnet
• Option to use SSL for JSON-RPC connections on unix/osx
• validateaddress RPC command

eurekafag:

• Russian translation

0.3.13

Version 0.3.13 is now available. You should upgrade to prevent potential problems with 0/unconfirmed transactions. Note: 0.3.13 prevents problems if you haven't already spent a 0/unconfirmed transaction, but if that already happened, you need 0.3.13.2.

Changes:

• Don't count or spend payments until they have 1 confirmation.
• Internal version number from 312 to 31300.
• Only accept transactions sent by IP address if -allowreceivebyip is specified.
• Dropped DB_PRIVATE Berkeley DB flag.
• Fix problem sending the last cent with sub-cent fractional change.
• Auto-detect whether to use 128-bit 4-way SSE2 on Linux.

Gavin Andresen:

• Option -rpcallowip= to accept json-rpc connections from another machine.
• Clean shutdown on SIGTERM on Linux.

Download: http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.3.13/

(Thanks Laszlo for the Mac OSX build!)

Note: The SSE2 auto-detect in the Linux 64-bit version doesn't work with AMD in 64-bit mode. Please try this instead and let me know if it gets it right: http://www.bitcoin.org/download/bitcoin-0.3.13.1-specialbuild-linux64.tar.gz

You can still control the SSE2 use manually with -4way and -4way=0.

Version 0.3.13.2 (SVN rev 161) has improvements for the case where you already had 0/unconfirmed transactions that you might have already spent. Here's a Windows build of it: http://www.bitcoin.org/download/bitcoin-0.3.13.2-win32-setup.exe

0.3.12

Version 0.3.12 is now available.

Features:

• json-rpc errors return a more standard error object. (thanks to Gavin Andresen)
• json-rpc command line returns exit codes.
• json-rpc "backupwallet" command.
• Recovers and continues if an exception is caused by a message you received. Other nodes shouldn't be able to cause an exception, and it hasn't happened before, but if a way is found to cause an exception, this would keep it from being used to stop network nodes.

If you have json-rpc code that checks the contents of the error string, you need to change it to expect error objects of the form {"code":<number>,"message":<string>}, which is the standard. See this thread: http://www.bitcoin.org/smf/index.php?topic=969.0
