Bitcoin Core 0.9.2 Released – Fixes Yet Another OpenSSL Vulnerability

Bitcoin Core 0.9.2 has been released and is available for download from https://bitcoin.org/bin/0.9.2/

This is minor release version containing mostly bug fixes and a few improvements to the code base and GUI.

Important: Users should upgrade to this release due to critical security updates in the included OpenSSL library (CVE-2014-0224 which is a new vulnerability – not the Heartbleed Bug)

General Users will benefit from the following improvements:

GUI

• Fix various coin control visual issues
• Show number of in/out connections in debug console
• Show weeks as well as years behind for long timespans behind
• Enable and disable the Show and Remove buttons for requested payments history based on whether any entry is selected
• Show also value for options overridden on command line in options dialog
• Fill in label from address book also for URIs
• Fixes feel when resizing the last column on tables (issue #2862)
• Fix ESC in disablewallet mode
• Add expert section to wallet tab in optionsdialog
• Do proper boost::path conversion (fixes unicode in datadir)
• Only override -datadir if different from the default (fixes -datadir in config file)
• Show rescan progress at start-up
• Show importwallet progress
• Get required locks upfront in polling functions (avoids hanging on locks)
• Catch Windows shutdown events while client is running
• Optionally add third party links to transaction context menu
• Check for !pixmap() before trying to export QR code (avoids crashes when no QR code could be generated)
• Fix “Start bitcoin on system login”

Wallet

• Make GetAvailableCredit run GetHash() only once per transaction (performance improvement)
• Lower paytxfee warning threshold from 0.25 BTC to 0.01 BTC
• Fix importwallet nTimeFirstKey (trigger necessary rescans)
• Log BerkeleyDB version at startup
• CWallet init fix

RPC

• Add getwalletinfo, getblockchaininfo and getnetworkinfo calls (will replace hodge-podge getinfo at some point)
• Add a relayfee field to getnetworkinfo
• Fix RPC related shutdown hangs and leaks
• Always show syncnode in getpeerinfo
• sendrawtransaction: report the reject code and reason, and make it possible to re-send transactions that are already in the mempool
• getmininginfo show right genproclimit

Command-line options

• Fix -printblocktree output
• Show error message if ReadConfigFile fails

Developers and node operators will notice the following changes:

The OpenSSL dependency in the gitian builds has been upgraded to 1.0.1h because of CVE-2014-0224 (new vulnerability – not the Heartbleed Bug).

Block-chain handling and storage

• Fix for GetBlockValue() after block 13,440,000 (BIP42)
• Upgrade leveldb to 1.17

Protocol and network code

• Per-peer block download tracking and stalled download detection
• Add new DNS seed from bitnodes.io
• Prevent socket leak in ThreadSocketHandler and correct some proxy related socket leaks
• Use pnode->nLastRecv as sync score (was the wrong way around)

Build system

• Add OSX build descriptors to gitian
• Fix explicit –disable-qt-dbus
• Don’t require db_cxx.h when compiling with wallet disabled and GUI enabled
• Improve missing boost error reporting
• Upgrade miniupnpc version to 1.9
• gitian-linux: –enable-glibc-back-compat for binary compatibility with old distributions
• gitian: don’t export any symbols from executable
• gitian: build against Qt 4.6
• devtools: add script to check symbols from Linux gitian executables
• Remove build-time no-IPv6 setting
