This document details the steps necessary to package a release of Bullet.

1) Preparing for release:

update VERSION in several places (/VERSION file, /CMakeLists.txt, /configure.ac, /src/LinearMath/btScalar.h, /src/LinearMath/btSerializer.h around line 441)
re-generate serialization structures, if they changed (/src/LinearMath/btSerializer.cpp using makesdna)
update ChangeLog with larger/important changes
regenerate MSVC project files using build/vs_all.bat
create a Subversion tag revision in bullet.googlecode.com/svn/tags/bullet-<VERSION>

2) Generating the release .zip:
Do an SVN export on a Windows machine into the directory: bullet-X.YY
prepare a zip file containing the directory

3) Generating the release .tar.gz:
Do an SVN export on a Unix machine into the directory: bullet-X.YY
prepare a .tar.gz file containing the directory

4) Uploading release to google code:

Google Code Bullet downloads URL: http://code.google.com/p/bullet/downloads/list

Title of release should follow this guide line: Bullet <VERSION> Physics SDK <Release Type> (revision)

It is better to upload the .tar.gz before the .zip so that the .zip appears first in the list

If the release is an Alpha/Beta or RC the tags should be: Type-Source, OpSys-ALL
If the release is a final release the tags should be: Type-Source, OpSys-ALL, Featured

5) Obsoleting old releases

Edit the tags on old releases and add the 'Deprecated' tag

6) Announcing final releases:
