Add all known release notes for versions since 0.3.12, thanks to Matt Corallo for collecting them on the wiki.
4.4 KiB
Bitcoin-Qt version 0.8.2 is now available from: http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.8.2/
This is a maintenance release that fixes many bugs and includes a few small new features.
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), 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 0.8.2 your blockchain files will be re-indexed, which will take anywhere from 30 minutes to several hours, depending on the speed of your machine.
0.8.2 Release notes
Fee Policy changes
The default fee for low-priority transactions is lowered from 0.0005 BTC (for each 1,000 bytes in the transaction; an average transaction is about 500 bytes) to 0.0001 BTC.
Payments (transaction outputs) of 0.543 times the minimum relay fee (0.00005430 BTC) are now considered 'non-standard', because storing them costs the network more than they are worth and spending them will usually cost their owner more in transaction fees than they are worth.
Non-standard transactions are not relayed across the network, are not included in blocks by most miners, and will not show up in your wallet until they are included in a block.
The default fee policy can be overridden using the -mintxfee and -minrelaytxfee command-line options, but note that we intend to replace the hard-coded fees with code that automatically calculates and suggests appropriate fees in the 0.9 release and note that if you set a fee policy significantly different from the rest of the network your transactions may never confirm.
