Bitcoin Core version 0.10.3 is now available from: |

<https://bitcoin.org/bin/bitcoin-core-0.10.3/> |

This is a new minor version release, bringing security fixes and translation |
||||||
|
updates. It is recommended to upgrade to this version as soon as possible. |

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. |
||||||
|
|
||||||
|
Notable changes |
||||||
|
=============== |
||||||
|
|
||||||
|
Fix buffer overflow in bundled upnp |
||||||
|
------------------------------------ |
||||||
|
|
||||||
|
Bundled miniupnpc was updated to 1.9.20151008. This fixes a buffer overflow in |
||||||
|
the XML parser during initial network discovery. |
||||||
|
|
||||||
|
Details can be found here: http://talosintel.com/reports/TALOS-2015-0035/ |
||||||
|
|
||||||
|
This applies to the distributed executables only, not when building from source or |
||||||
|
using distribution provided packages. |
||||||
|
|
||||||
|
Additionally, upnp has been disabled by default. This may result in a lower |
||||||
|
number of reachable nodes on IPv4, however this prevents future libupnpc |
||||||
|
vulnerabilities from being a structural risk to the network |
||||||
|
(see https://github.com/bitcoin/bitcoin/pull/6795). |
||||||
|
|
||||||
|
Test for LowS signatures before relaying |
||||||
|
----------------------------------------- |
||||||
|
|
||||||
|
Make the node require the canonical 'low-s' encoding for ECDSA signatures when |
||||||
|
relaying or mining. This removes a nuisance malleability vector. |
||||||
|
|
||||||
|
Consensus behavior is unchanged. |
||||||
|
|
||||||
|
If widely deployed this change would eliminate the last remaining known vector |
||||||
|
for nuisance malleability on SIGHASH_ALL P2PKH transactions. On the down-side |
||||||
|
it will block most transactions made by sufficiently out of date software. |
||||||
|
|
||||||
|
Unlike the other avenues to change txids on transactions this |
||||||
|
one was randomly violated by all deployed bitcoin software prior to |
||||||
|
its discovery. So, while other malleability vectors where made |
||||||
|
non-standard as soon as they were discovered, this one has remained |
||||||
|
permitted. Even BIP62 did not propose applying this rule to |
||||||
|
old version transactions, but conforming implementations have become |
||||||
|
much more common since BIP62 was initially written. |
||||||
|
|
||||||
|
Bitcoin Core has produced compatible signatures since a28fb70e in |
||||||
|
September 2013, but this didn't make it into a release until 0.9 |
||||||
|
in March 2014; Bitcoinj has done so for a similar span of time. |
||||||
|
Bitcoinjs and electrum have been more recently updated. |
||||||
|
|
||||||
|
This does not replace the need for BIP62 or similar, as miners can |
||||||
|
still cooperate to break transactions. Nor does it replace the |
||||||
|
need for wallet software to handle malleability sanely[1]. This |
||||||
|
only eliminates the cheap and irritating DOS attack. |

||||||
|
Minimum relay fee default increase |
||||||
|
----------------------------------- |
||||||
|
|
||||||
|
The default for the `-minrelaytxfee` setting has been increased from `0.00001` |
||||||
|
to `0.00005`. |
||||||
|
|
||||||
|
This is necessitated by the current transaction flooding, causing |
||||||
|
outrageous memory usage on nodes due to the mempool ballooning. This is a |
||||||
|
temporary measure, bridging the time until a dynamic method for determining |
||||||
|
this fee is merged (which will be in 0.12). |
||||||
|
|
||||||
|

||||||
|
release notes, in which this value was suggested) |
