Reindexing using earlier versions will also not work +anymore as a result of this. + +* The block index database will now hold headers for which no block is +stored on disk, which earlier versions won't support. + +If you want to be able to downgrade smoothly, make a backup of your entire data +directory. Without this your node will need start syncing (or importing from +bootstrap.dat) anew afterwards. + +This does not affect wallet forward or backward compatibility. + Transaction fee changes ======================= diff --git a/doc/release-notes/release-notes-0.9.3.md b/doc/release-notes/release-notes-0.9.3.md new file mode 100644 index 0000000000..0765a360b2 --- /dev/null +++ b/doc/release-notes/release-notes-0.9.3.md @@ -0,0 +1,101 @@ +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.

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/). |
