It is +recommended to upgrade to this version as soon as possible. + +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). + +Downgrade warning +------------------ + +Because release 0.10.0 and later makes use of headers-first synchronization and +parallel block download (see further), the block files and databases are not +backwards-compatible with pre-0.10 versions of Bitcoin Core or other software: + +* Blocks will be stored on disk out of order (in the order they are +received, really), which makes it incompatible with some tools or +other programs. 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. It is possible that the data from a completely +synchronised 0.10 node may be usable in older versions as-is, but this is not +supported and may break as soon as the older version attempts to reindex. + +This does not affect wallet forward or backward compatibility. There are no +known problems when downgrading from 0.11.x to 0.10.x. + +Notable changes since 0.10.3 +============================ + +BIP65 soft fork to enforce OP_CHECKLOCKTIMEVERIFY opcode +-------------------------------------------------------- + +This release includes several changes related to the [BIP65][] soft fork +which redefines the existing OP_NOP2 opcode as OP_CHECKLOCKTIMEVERIFY +(CLTV) so that a transaction output can be made unspendable until a +specified point in the future. + +1. This release will only relay and mine transactions spending a CLTV + output if they comply with the BIP65 rules as provided in code. + +2. This release will produce version 4 blocks by default. Please see the + *notice to miners* below. + +3. Once 951 out of a sequence of 1,001 blocks on the local node's best block + chain contain version 4 (or higher) blocks, this release will no + longer accept new version 3 blocks and it will only accept version 4 + blocks if they comply with the BIP65 rules for CLTV. + +For more information about the soft-forking change, please see +<https://github.com/bitcoin/bitcoin/pull/6351> + +Graphs showing the progress towards block version 4 adoption may be +found at the URLs below: + +- Block versions over the last 50,000 blocks as progress towards BIP65 + consensus enforcement: <http://bitcoin.sipa.be/ver-50k.png> + +- Block versions over the last 2,000 blocks showing the days to the + earliest possible BIP65 consensus-enforced block: <http://bitcoin.sipa.be/ver-2k.png> + +**Notice to miners:** Bitcoin Core’s block templates are now for +version 4 blocks only, and any mining software relying on its +getblocktemplate must be updated in parallel to use libblkmaker either +version FIXME or any version from FIXME onward. + +- If you are solo mining, this will affect you the moment you upgrade + Bitcoin Core, which must be done prior to BIP65 achieving its 951/1001 + status. + +- If you are mining with the stratum mining protocol: this does not + affect you. + +- If you are mining with the getblocktemplate protocol to a pool: this + will affect you at the pool operator’s discretion, which must be no + later than BIP65 achieving its 951/1001 status. + +[BIP65]: https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki + +Windows bug fix for corrupted UTXO database on unclean shutdowns +---------------------------------------------------------------- + +Several Windows users reported that they often need to reindex the +entire blockchain after an unclean shutdown of Bitcoin Core on Windows +(or an unclean shutdown of Windows itself). Although unclean shutdowns +remain unsafe, this release no longer relies on memory-mapped files for +the UTXO database, which significantly reduced the frequency of unclean +shutdowns leading to required reindexes during testing. + +For more information, see: <https://github.com/bitcoin/bitcoin/pull/6917> + +Other fixes for database corruption on Windows are expected in the +next major release. + +0.10.4 Change log +================= + +Detailed release notes follow.
