Topic: New Version 0.9.4 Just Released in Ubuntu PPA Repository (Read 941 times)

@Chemistry1988 , for some reasons your link https://bitcoin.org/bin/0.9.4/ is going back to bitcoin.org homepage so I can't really download or see the windows version

The Windows iteration is not available yet.  I just checked.  Someone else might know the expected release date.

The 0.10.0c1 is a pre-release, development version.. to be replaced by the official 0.9.4 version.  I think the Linux iteration of the official version release is usually published first.  This is what you have here.

Duh, what has changed?

Bitcoin Core version 0.9.4 is now available from:

https://bitcoin.org/bin/0.9.4/

This is a new minor version release, bringing only bug fixes and updated translations. Upgrading to this release is recommended.

Please report bugs using the issue tracker at github:

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).

OpenSSL Warning
OpenSSL 1.0.0p / 1.0.1k was recently released and is being pushed out by various operating system maintainers. Review by Gregory Maxwell determined that this update is incompatible with the Bitcoin system and could lead to consensus forks.

Bitcoin Core released binaries from https://bitcoin.org are unaffected, as are any built with the gitian deterministic build system.

However, if you are running either

A third-party or self-compiled Bitcoin Core
upgrade to Bitcoin Core 0.9.4, which includes a workaround, before updating OpenSSL.

The incompatibility is due to the OpenSSL update changing the behavior of ECDSA validation to reject any signature which is not encoded in a very rigid manner. This was a result of OpenSSL's change for CVE-2014-8275 "Certificate fingerprints can be modified".

We are specifically aware of potential hard-forks due to signature encoding handling and had been hoping to close them via BIP62 in 0.10. BIP62's purpose is to improve transaction malleability handling and as a side effect rigidly defines the encoding for signatures, but the overall scope of BIP62 has made it take longer than we'd like to deploy.
