515  Bitcoin / Bitcoin Discussion / Bitcoin Core version 0.11.1 released on: October 15, 2015, 02:32:47 PM
Bitcoin Core version 0.11.1 is now available from:

https://bitcoin.org/bin/bitcoin-core-0.11.1/

This is a new minor version release, bringing security fixes. 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 wont 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

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.

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 didnt 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.
