If you are an avid follower of V8 development, often you want to try out the same V8 version which is used in a certain release of Google Chrome. How do we find this? It’s actually rather easy. First, look at the
releases branches of Chromium Subversion repository, conveniently browseable at src.chromium.org/viewvc/chrome/releases. Now it’s a matter of checking the right version. At the moment of this writing, my Google Chrome says its at version 17.0.963.46. When viewing the file 17.0.963.46/DEPS (used by Gyp, the build system), you’ll find the link to the right version of V8, i.e. v8.googlecode.com/svn/branches/3.7 revision 10521. This can be cross-referenced in V8 repository: branches/3.7&start=10521.
Easy, isn’t it?
