This new version fixes issues that many customers have had with rubies built with darwin15 (OSX 10.11).<p>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.<p>This resolves many issues raised by therubyracer users:<p><a href="https:&#x2F;&#x2F;github.com&#x2F;cowboyd&#x2F;libv8&#x2F;issues#205" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;cowboyd&#x2F;libv8&#x2F;issues#205</a><p><a href="https:&#x2F;&#x2F;github.com&#x2F;cowboyd&#x2F;therubyracer#405" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;cowboyd&#x2F;therubyracer#405</a><p><a href="https:&#x2F;&#x2F;github.com&#x2F;cowboyd&#x2F;therubyracer#403" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;cowboyd&#x2F;therubyracer#403</a><p>Despite what the changelog states, this is indeed released, thanks to @ignisf.<p>For the record, the error was looking like that:<p><pre><code>    In file included from ..&#x2F;src&#x2F;elements.h:32:
