1 Bitcoin-Qt version 0.8.5 is now available from: 2 http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.8.5/ 3 4 This is a maintenance release to fix a critical bug; 5 we urge all users to upgrade. 6 7 Please report bugs using the issue tracker at github: 8 https://github.com/bitcoin/bitcoin/issues 9 10 11 How to Upgrade 12 -------------- 13 14 If you are running an older version, shut it down. Wait 15 until it has completely shut down (which might take a few minutes for older 16 versions), then run the installer (on Windows) or just copy over 17 /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux). 18 19 If you are upgrading from version 0.7.2 or earlier, the first time you 20 run 0.8.5 your blockchain files will be re-indexed, which will take 21 anywhere from 30 minutes to several hours, depending on the speed of 22 your machine. 23 24 0.8.5 Release notes 25 =================== 26 27 Bugs fixed 28 ---------- 29 30 Transactions with version numbers larger than 0x7fffffff were 31 incorrectly being relayed and included in blocks. 32 33 Blocks containing transactions with version numbers larger 34 than 0x7fffffff caused the code that checks for LevelDB database 35 inconsistencies at startup to erroneously report database 36 corruption and suggest that you reindex your database. 37 38 This release also contains a non-critical fix to the code that 39 enforces BIP 34 (block height in the coinbase transaction). 40 41 -- 42 43 Thanks to Gregory Maxwell and Pieter Wuille for quickly 44 identifying and fixing the transaction version number bug.
