There were no changes from 0.8.4 release candidate 2, so if you are running 0.8.4rc2 you do not need to upgrade. 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 0.8.4 your blockchain files will be re-indexed, which will take anywhere from 30 minutes to several hours, depending on the speed of your machine. 0.8.4 Release notes =================== Security issues --------------- An attacker could send a series of messages that resulted in an integer division-by-zero error in the Bloom Filter handling code, causing the Bitcoin-Qt or bitcoind process to crash. Bloom filters were introduced with version 0.8, so versions 0.8.0 through 0.8.3 are vulnerable to this critical denial-of-service attack. A constant-time algorithm is now used to check RPC password guess attempts; fixes https://github.com/bitcoin/bitcoin/issues/2838 (CVE-2013-4165) Implement a better fix for the fill-memory-with-orphan-transactions attack that was fixed in 0.8.3. See https://bitslog.wordpress.com/2013/07/18/buggy-cve-2013-4627-patch-open-new-vectors-of-attack/ for a description of the weaknesses of the previous fix. (CVE-2013-4627) Bugs fixed ---------- Fix multi-block reorg transaction resurrection. Fix non-standard disconnected transactions causing mempool orphans. This bug could cause nodes running with the -debug flag to crash. OSX: use 'FD_FULLSYNC' with LevelDB, which will (hopefully!) prevent the database corruption issues many people have experienced on OSX. Linux: clicking on bitcoin: links was broken if you were using a Gnome-based desktop. Fix a hang-at-shutdown bug that only affects users that compile their own version of Bitcoin against Boost versions 1.50-1.52. Other changes ------------- Checkpoint at block 250,000 to speed up initial block downloads and make the progress indicator when downloading more accurate.
