* update (commit) version in sources
  src/serialize.h
  share/setup.nsi

* update (commit) version in OSX app bundle
 contrib/Bitcoin.app/Contents/Info.plist

  * CFBundleShortVersionString should have value like 0.5.0
  * CFBundleVersion should have value like 500

* tag version in git

   git tag -a v0.5.0

* write release notes.  git shortlog helps a lot:

   git shortlog --no-merges v0.4.0..

* create source-only archive

   git archive --format=tar --prefix=bitcoin-0.5.0/ HEAD | \
  	gzip -9c > ~/tmp/bitcoin-0.5.0-src.tar.gz 

* perform gitian builds

  * From a directory containing the bitcoin source, gitian-builder and gitian.sigs
   export SIGNER=(your gitian key, ie bluematt, sipa, etc)
   export VERSION=0.5.0
   cd ./gitian-builder

  * Fetch and build inputs:
   mkdir -p inputs; cd inputs/
   wget 'http://miniupnp.free.fr/files/download.php?file=miniupnpc-1.6.tar.gz' -O miniupnpc-1.6.tar.gz
   wget 'http://www.openssl.org/source/openssl-1.0.0e.tar.gz'
   wget 'http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz'
   wget 'http://downloads.sourceforge.net/project/boost/boost/1.47.0/boost_1_47_0.tar.bz2'
   wget 'http://download.qt.nokia.com/qt/source/qt-everywhere-opensource-src-4.7.4.tar.gz'
   cd ..
   ./bin/gbuild ../bitcoin/contrib/gitian-descriptors/boost-win32.yml
   cp build/out/boost-win32-1.47.0-gitian.zip inputs/
   ./bin/gbuild ../bitcoin/contrib/gitian-descriptors/qt-win32.yml
   cp build/out/qt-win32-4.7.4-gitian.zip inputs/

  * Build bitcoind and bitcoin-qt on Linux32, Linux64, and Win32:
   ./bin/gbuild --commit bitcoin=v$VERSION ../bitcoin/contrib/gitian-descriptors/gitian.yml
   ./bin/gsign --signer $SIGNER --release $VERSION --destination ../gitian.sigs/ ../bitcoin/contrib/gitian-descriptors/gitian.yml
   pushd build/out
   zip -r bitcoin-$VERSION-linux-gitian.zip *
   mv bitcoin-$VERSION-linux-gitian.zip ../../
   popd
   ./bin/gbuild --commit bitcoin=v$VERSION ../bitcoin/contrib/gitian-descriptors/gitian-win32.yml
   ./bin/gsign --signer $SIGNER --release $VERSION-win32 --destination ../gitian.sigs/ ../bitcoin/contrib/gitian-descriptors/gitian-win32.yml
   pushd build/out
   zip -r bitcoin-$VERSION-win32-gitian.zip *
   mv bitcoin-$VERSION-win32-gitian.zip ../../
   popd

  Build output expected:
  1. linux 32-bit and 64-bit binaries + source (bitcoin-$VERSION-linux-gitian.zip)
  2. windows 32-bit binary, installer + source (bitcoin-$VERSION-win32-gitian.zip)
  3. Gitian signatures (in gitian.sigs/$VERSION[-win32]/(your gitian key)/

* repackage gitian builds for release as stand-alone zip/tar/installer exe

  * Linux .tar.gz:
   unzip bitcoin-$VERSION-linux-gitian.zip -d bitcoin-$VERSION-linux
   tar czvf bitcoin-$VERSION-linux.tar.gz bitcoin-$VERSION-linux
   rm -rf bitcoin-$VERSION-linux

  * Windows .zip and setup.exe:
   unzip bitcoin-$VERSION-win32-gitian.zip -d bitcoin-$VERSION-win32
   mv bitcoin-$VERSION-win32/bitcoin-*-setup.exe .
   zip -r bitcoin-$VERSION-win32.zip bitcoin-$VERSION-win32
   rm -rf bitcoin-$VERSION-win32

* perform Mac build
  See this blog post for how Gavin set up his build environment and
  patched macdeployqt to build the OSX release:
    http://gavintech.blogspot.com/2011/11/deploying-bitcoin-qt-on-osx.html
  qmake USE_SSL=1 USE_UPNP=1 bitcoin-qt.pro
  make
  export QTDIR=/opt/local/share/qt4  # needed to find translations/qt_*.qm files
  T=$(contrib/qt_translations.py $QTDIR/translations src/qt/locale)
  contrib/macdeploy/macdeployqtplus Bitcoin-Qt.app -add-qt-tr $T -dmg -fancy contrib/macdeploy/fancy.plist  

 Build output expected:
  Bitcoin-Qt.dmg

* upload source and builds to SourceForge

* create SHA1SUMS for builds, and PGP-sign it

* update bitcoin.org version

* update forum version

* update wiki

* update wiki download links

* release gitian-signed gitian archives

  * Collect enough gitian signatures to meet minimum_weight (see contrib/gitian-downloader/*-download-config)

  * From a directory containing bitcoin source, gitian.sigs and gitian zips
   export VERSION=0.5.0
   mkdir bitcoin-$VERSION-linux-gitian; cd bitcoin-$VERSION-linux-gitian
