Bitcoin Core version 0.9.3 is now available from: https://bitcoin.org/bin/0.9.3/ This is a new minor version release, bringing only bug fixes and updated translations. 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 0.9.3 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). 0.9.3 Release notes ======================= RPC: - Avoid a segfault on getblock if it can't read a block from disk - Add paranoid return value checks in base58 Protocol and network code: - Don't poll showmyip.com, it doesn't exist anymore - Add a way to limit deserialized string lengths and use it - Add a new checkpoint at block 295,000 - Increase IsStandard() scriptSig length - Avoid querying DNS seeds, if we have open connections - Remove a useless millisleep in socket handler - Stricter memory limits on CNode - Better orphan transaction handling - Add `-maxorphantx=<n>` and `-maxorphanblocks=<n>` options for control over the maximum orphan transactions and blocks Wallet: - Check redeemScript size does not exceed 520 byte limit - Ignore (and warn about) too-long redeemScripts while loading wallet GUI: - fix 'opens in testnet mode when presented with a BIP-72 link with no fallback' - AvailableCoins: acquire cs_main mutex - Fix unicode character display on MacOSX Miscellaneous: - key.cpp: fail with a friendlier message on missing ssl EC support - Remove bignum dependency for scripts - Upgrade OpenSSL to 1.0.1i (see https://www.openssl.org/news/secadv_20140806.txt - just to be sure, no critical issues for Bitcoin Core) - Upgrade miniupnpc to 1.9.20140701 - Fix boost detection in build system on some platforms Credits -------- Thanks to everyone who contributed to this release: - Andrew Poelstra - Cory Fields - Gavin Andresen - Jeff Garzik - Johnathan Corgan - Julian Haight - Michael Ford - Pavel Vasin - Peter Todd - phantomcircuit - Pieter Wuille - Rose Toomey - Ruben Dario Ponticelli - shshshsh - Trevin Hofmann - Warren Togami - Wladimir J. van der Laan - Zak Wilcox As well as everyone that helped translating on [Transifex](https://www.transifex.com/projects/p/bitcoin/).
