Bitcoin Core version 0.10.4 is now available from:
|
||
|
||
<https://bitcoin.org/bin/bitcoin-core-0.10.4/>
|
||
|
||
This is a new minor version release, bringing bug fixes, the BIP65
|
||
(CLTV) consensus change, and relay policy preparation for BIP113. 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:

||

||

|
||
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.

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.
