Release Process
====================

* update translations (ping wumpus, Diapolo or tcatm on IRC)
* see https://github.com/bitcoin/bitcoin/blob/master/doc/translation_process.md#syncing-with-transifex

* * *

###update (commit) version in sources

	doc/README*
	src/clientversion.h (change CLIENT_VERSION_IS_RELEASE to true)

###tag version in git

	git tag -s v(new version, e.g. 0.8.0)

###write release notes. git shortlog helps a lot, for example:

	git shortlog --no-merges v(current version, e.g. 0.7.2)..v(new version, e.g. 0.8.0)

* * *

###perform gitian builds

 From a directory containing the twister source, gitian-builder and gitian.sigs
  
#	export SIGNER=(your gitian key, ie bluematt, sipa, etc)
	export VERSION=(new version, e.g. 0.8.0)
	pushd ./twister-core
	git checkout v${VERSION}
	popd
	pushd ./gitian-builder

###fetch and build inputs: (first time, or when dependency versions change)
 
	mkdir -p inputs; cd inputs/

 Register and download the Apple SDK: (see OSX Readme for details)
 
 https://developer.apple.com/downloads/download.action?path=Developer_Tools/xcode_4.6.3/xcode4630916281a.dmg
 
 Using a Mac, create a tarball for the 10.7 SDK and copy it to the inputs directory:
 
	tar -C /Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/ -czf MacOSX10.7.sdk.tar.gz MacOSX10.7.sdk

 Download remaining inputs, and build everything:

 Build twister-core for Linux, Windows, and OS X:
  
#	./bin/gbuild --commit twister-core=v${VERSION} ../twister-core/contrib/gitian-descriptors/gitian-win.yml
	./bin/gbuild --commit twister-core=HEAD ../twister-core/contrib/gitian-descriptors/gitian-win.yml
#	./bin/gsign --signer $SIGNER --release ${VERSION}-win --destination ../gitian.sigs/ ../bitcoin/contrib/gitian-descriptors/gitian-win.yml
	pushd build/out
	zip -r bitcoin-${VERSION}-win-gitian.zip *
	mv bitcoin-${VERSION}-win-gitian.zip ../../../
	popd

  Build output expected:

#  1. linux 32-bit and 64-bit binaries + source (bitcoin-${VERSION}-linux-gitian.zip)
  2. windows 32-bit and 64-bit binaries + installer + source (bitcoin-${VERSION}-win-gitian.zip)
#  3. OSX installer (Bitcoin-Qt.dmg)
#  4. Gitian signatures (in gitian.sigs/${VERSION}-<linux|win|osx>/(your gitian key)/

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