Bitcoin Core version 0.9.2 is now available from: https://bitcoin.org/bin/0.9.2/ This is a new minor version release, bringing mostly bug fixes and some minor improvements. OpenSSL has been updated because of a security issue (CVE-2014-0224). Upgrading to this release is recommended. Please report bugs using the issue tracker at github: https://github.com/bitcoin/bitcoin/issues Upgrading and downgrading ========================== 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 0.9.0 your blockchain files will be re-indexed, which will take anywhere from 30 minutes to several hours, depending on the speed of your machine. Downgrading warnings -------------------- The 'chainstate' for this release is not always compatible with previous releases, so if you run 0.9.x 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). Important changes ================== Gitian OSX build ----------------- The deterministic build system that was already used for Windows and Linux builds is now used for OSX as well. Although the resulting executables have been tested quite a bit, there could be possible regressions. Be sure to report these on the Github bug tracker mentioned above. Compatibility of Linux build ----------------------------- For Linux we now build against Qt 4.6, and filter the symbols for libstdc++ and glibc. This brings back compatibility with - Debian 6+ / Tails - Ubuntu 10.04 - CentOS 6.5 0.9.2 Release notes ======================= The OpenSSL dependency in the gitian builds has been upgraded to 1.0.1h because of CVE-2014-0224.
