1Bitcoin Core version 0.10.2 is now available from:3<https://bitcoin.org/bin/bitcoin-core-0.10.2/>5This is a new minor version release, bringing minor bug fixes and translation6updates. It is recommended to upgrade to this version.8Please report bugs using the issue tracker at github:10<https://github.com/bitcoin/bitcoin/issues>12Upgrading and downgrading13=========================15How to Upgrade16--------------18If you are running an older version, shut it down. Wait until it has completely19shut down (which might take a few minutes for older versions), then run the20installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or21bitcoind/bitcoin-qt (on Linux).23Downgrade warning24------------------26Because release 0.10.0 and later makes use of headers-first synchronization and27parallel block download (see further), the block files and databases are not28backwards-compatible with pre-0.10 versions of Bitcoin Core or other software:30* Blocks will be stored on disk out of order (in the order they are31received, really), which makes it incompatible with some tools or32other programs. Reindexing using earlier versions will also not work33anymore as a result of this.35* The block index database will now hold headers for which no block is36stored on disk, which earlier versions won't support.38If you want to be able to downgrade smoothly, make a backup of your entire data39directory. Without this your node will need start syncing (or importing from40bootstrap.dat) anew afterwards. It is possible that the data from a completely41synchronised 0.10 node may be usable in older versions as-is, but this is not42supported and may break as soon as the older version attempts to reindex.44This does not affect wallet forward or backward compatibility.46Notable changes47===============49This fixes a serious problem on Windows with data directories that have non-ASCII50characters (https://github.com/bitcoin/bitcoin/issues/6078).52For other platforms there are no notable changes.54For the notable changes in 0.10, refer to the release notes55at https://github.com/bitcoin/bitcoin/blob/v0.10.0/doc/release-notes.md570.10.2 Change log58=================60Detailed release notes follow.
