This new version fixes issues that many customers have had with rubies built with darwin15 (OSX 10.11).
For this version, no V8 pre-compiled binaries were available. So the install fallbacks on the source, and people with XCode 7.3 installed were unable to compile V8 as is - because Clang 7.3 now enables the -Wshift-negative-value warning - itself turned into error by a global -Werror defined in libv8.
This resolves many issues raised by therubyracer users:

Despite what the changelog states, this is indeed released, thanks to @ignisf.
For the record, the error was looking like that:
In file included from ../src/elements.h:32:
../src/objects.h:5252:44: error: shifting a negative signed value is undefin
